'''XBMC has been accepted into the Google Summer of Code 2008!'''
+
The purpose of this guide is to give a hand to new XBMC users, who want to build a Linux based, dedicated [http://en.wikipedia.org/wiki/Home_theater_PC HTPC (Home Theater PC)], a true living-room media center computer, but don't have any knowledge and experience in the Linux world.

Google is sponsoring their fourth annual [http://code.google.com/soc/ Summer of Code (GSoC)] in the summer of 2008, this entail sponsoring students to work on assorted open source projects as well as sponsoring mentors in those same projects, everyone wins! XBMC has been selected as one of the approved mentoring organizations for this year's GSoC. This page will be used for possible project ideas for the [http://code.google.com/soc/2008 Google Summer of Code 2008 season], and also track the status of each project and how well each student is doing.

You always have the chance to try [[XBMC Live]] to test/demo XBMC Media Center, but if you want to have more control and more customization possibilities, than a Linux installation like in this guide is more suitable.
  
:NOTE! '''If you are a student''' who wishes to be '''involved with an XBMC GSoC project''', one of the first and best steps you can take is to register an account on [http://forum.xbmc.org XBMC community forum], (sooner rather than later), and indicate your interest. Also, make sure that you '''complete''' a qualification task as soon as possible to be eligible for a XBMC SoC project, (no qualification task = no project, that is Team-XBMC policy, not Google).

= Introduction =
 +
This is a real step-by-step guide, I hope everybody can follow and walk through the whole installation procedure. The guide is based on either Ubuntu 8.04 (Hardy Heron) or 8.10 (Intrepid Ibex) as a platform, start with a minimal install and only install the needed components at the top of that.
  
==Introduction to XBMC==
+
On the face of it, maybe seems very lengthy process, but you will feel shorter while you follow it.
XBMC (formerly "XBox Media Center") is a free and open source (GPL) cross-platform media player and entertainment hub software. XBMC was originally established in 2002 and in the beginning developed as XBox Media Player (XBMP) for the first-generation Xbox game-console. XBMC has since been ported to also run natively under Linux, Mac OS X, and Microsoft Windows operating-system. XBMC has so far been translated to over 30 languages, won two SourceForge Community Choice Awards, (Best Multimedia Project and Best Game Project back in 2006), and today XBMC has a very broad international community of active developers, graphic artists, and devoted users.

I therefor assume that you use digital audio pass-through (S/PDIF or HDMI) to a receiver/amplifier with built-in Dolby Digital (AC3) decoder, and hence I choose NOT to install the dependency libraries for PulseAudio and compile XBMC later without PulseAudio support.
  
===Developing XBMC===
+
'''You will get:'''
The XBMC code structure uses a fairly modular design (with libraries and DLLs) who's structure is large, though relatively easy to grasp. XBMC's source code is predominantly C++, though there is a small splattering of C libraries and assembler for good measure. XBMC for uses the Microsoft DirectX multimedia framework (Direct3D) on the Xbox, and the [http://en.wikipedia.org/wiki/Simple_DirectMedia_Layer SDL (Simple DirectMedia Layer) framework with OpenGL rendering] for other operating-system platforms versions of XBMC, (ie. [[XBMC for Linux port project|Linux]], [[XBMC for Mac OS X port project|Mac OS X]], and [[XBMC for Windows port project|Microsoft Windows]]).
+
* A dedicated HTPC which auto-boots directly to XBMC Media Center.
 +
* Latest XBMC SVN version.
 +
* Updated ALSA (audio) driver.
 +
* Updated VIDEO (graphics) driver.
 +
* LIRC (Microsoft MCE Remote will work out-of-the-box, however if you have any other remotes and/or LCD displays then you are on your own to solve the individual LIRC and LCDproc issues).
 +
* Suspend/resume (works perfectly on for example ASUS P5N7A-VM motherboard with Intrepid).
  
The main XBMC program is developed using [http://en.wikipedia.org/wiki/Microsoft_Visual_Studio Microsoft Visual Studio] for the Xbox and win32 builds, and there are [http://en.wikipedia.org/wiki/KDevelop KDevelop] project files for Linux, and [http://en.wikipedia.org/wiki/Eclipse_%28software%29 Eclipse]/[http://en.wikipedia.org/wiki/Xcode Xcode] project files for Mac OS X).  For the Xbox version a copy of the latest Microsoft Xbox SDK (a.k.a. XDK) is also required, though obviously this is not required for all other platforms.
+
'''Known issues:'''
 +
* Installations based on Intrepid having some performance issues, due to unidetified reason. You can read more on that [http://forum.xbmc.org/showthread.php?t=43075 here].
 +
* You might have some difficulties with suspend/ resume on Hardy based installation
  
XBMC's code also contains three player cores: One core based on [[MPlayer]] that is only available to the Xbox version of XBMC, another [[DVDPlayer|in-house developed (FFmpeg-based) dedicated video-player core]] (which also supports DVD-Video movies with menus), and an [[PAPlayer|in-house developed dedicated music-player core]].

== How To Apply as a Student ==
+
Now perform a default install.
  
===Before you can apply===
+
* '''When asked during the installation, please set „xbmc” as username and password at the account creation.'''
Before you can apply make sure you are qualified to apply:
+
* You have to know how to program in C++ (and know C) fairly well.
+
* We would like you to first submit a small patch that fixes a bug or adds a feature to XBMC. By doing that we will know if you are qualified for the task or not. At the bottom of this page there will be a list of possible [[Google Summer of Code 2008#Qualification_tasks|Qualification Tasks]], specific ideas that could be performed to show your skill, however you are free to submit anything you feel might be of value to XBMC. The qualification task can be done after you have filed you application.
+
* Submit a good application through the formal Google Summer of Code process during the application time frame.
+
* You have to have >35 hours per week to put into the project.
+
* You can not have another job at the same time as the GSoC project.
+
  
===Applying===
+
* At the end, when you have to choose from the optional components, check only „OpenSSH” to be able to access your HTPC remotely via SSH.
If you are interested in participating in the Google Summer of Code you will need to register at the official GSoC site linked below and file an official application. Traditionally, the top applications are fairly detailed - you really need to sell yourself as well as your idea proposal. Look for example at this application [http://vfer.sourceforge.net/cgi-bin/index.cgi?page=writeup here] for inspiration. The official guide from Google can be found here:
+
* [http://groups.google.com/group/google-summer-of-code-announce/web/guide-to-the-gsoc-web-app-for-student-applicants Guide to the Google Summer of Code Web Application for Student Applicants]
+
* [http://code.google.com/soc/2008/student_step1.html Google Summer of Code - Student Signup]
+
  
*Sell your idea - Describe your idea in detail. What is the ultimate goal? What components will it have? What are the benefits for the user? How do you plan to ensure that the project gets completed on time? If a more detailed explanation of the idea already exists, what will you do that will go above and beyond all expectations?
+
''Apparently there seems to be an issue with '''''Intrepid''''' installer. If you are using flash drive, it's not installing GRUB for some reason.'' '''''<BR>This is only affect Intrepid, and only when you are installing it onto a flash drive.'''''
  
*Sell yourself - Make sure you get across how enthusiastic you are about the project. The more enthusiastic you are, the more assured we will be that you will finish your project. It also indicates that there is a good chance you will stick around even after the Summer of Code has finished. Why are you interested in Open Source and XBMC in particular? What interests do you have, and how do these relate to the project for which you are applying?
+
''To handle this, you have to options:''
 +
# ''Either install Hardy(Ubuntu 8.04) mini.iso first, which is installing GRUB correctly, then right after that, install Intrepid mini.iso over the same flash drive. It will reformat the drive, but GRUB will stay alive on the drive.''
 +
# ''Second option is that right after Intrepid mini installation, boot up Intrepid mini.iso from the CD again, choose rescue mode, and there you will find an "install GRUB" option.''
  
*Be enthusiastic - Summer of Code is a very exciting opportunity, and XBMC is a very exciting project to work on. We aren't just looking for someone who wants a summer job to pass their time and earn some money. We want people who have a passion towards open source and are likely to become constant contributors to XBMC and open source also once the summer has passed. The goal of the whole initiative is to have students find their way to open source together with mentoring and a good motivation.  
+
After you’ve done, boot it up, then use an SSH application (e.g. putty) to log in remotely from your desktop, using the above created username and password. This way, you will be able to copy/ paste all the steps below. Alternatively you can use console on the htpc too, but then you will have a hard time type in everything.

== Project Proposals ==
+
During the installation of the packages, there will be a popup window to choose your locale languages to let "localepurge" know which locales not to remove in further installations. I would suggest to keep all en_us (3 all together) and your own country locales (again should be 3) as well. Localepurge will save you some space with removing unneccessary languages.<BR>
=== Overview ===
+
Qualifications for a good Summer of Code proposal:
+
* Discrete, well-defined, modular
+
* Comprised of a series of measurable sub-goals
+
* Based on open specs that are available free of charge
+
* Based on complete specs
+
An example of a good proposal is the implementation of a new feature or function that is not yet available in XBMC.
+
  
An example of a less desirable proposal is one that's not as measurable, such as refactoring an existing API. Bad proposals tend to be ones that would require touching a lot of core code.
+
= Upgrading ALSA (sound driver) to the latest version =
  
To re-iterate:
+
I have modified the ALSA upgrade script (available at Ubuntuforums), and now it is working with only “-di” option in our case here (Also on ASUS P5N7A-VM).
* Localized/isolated code projects = ''good''
+
* Global code refactoring = ''bad''

=== Team-XBMC proposal ideas up for discussion ===
 
Most of the proposals in this list are just some project ideas that we have been kicking around, (which, by no means, limits any prospective proposals). So you are more than welcome to come up with a new idea that you think falls into the scope of XBMC and the Google Summer of Code spirit. Since XBMC is cross-platform software most of these ideas are platform-independent, meaning that if you implement the feature/function on one operating-system platform then someone else will be able to port that feature/function to the other operating-system platforms that XBMC runs on.
 
  
'''NOTE!''' THIS LIST IS NOT THE FINAL PROPOSALS THAT WILL BE SUBMITTED. THESE ARE ONLY CONCEPTS THAT IDEAS COULD BE BASED UPON, IN THE END YOU AS THE STUDENT WILL BE PRESENTING THE IDEA AS YOUR '''OWN''', SO IT IS NOT ONLY THE IDEA BUT HOW '''YOU''' PRESENT IT, SO BE CREATIVE!

== Qualification tasks ==
+
'''NEXT STEP'''<BR>
Please add a note here if you choose to work on a qualification task to avoid duplicate work. (To do so you need to register an account on this wiki and request 'ninja status' from a Team-XBMC member for that account).

Many students will probably apply for the Google Summer of Code and wish to work on a sexy multimedia project such as XBMC. All students will probably also claim to be hard workers, but we need a real method of determining which students have a higher probability for success. Thus, we will use this qualification system (adopted from FFmpeg SoC 2007 season). A student must successfully first complete a qualification task in order to be considered for an XBMC SoC project. In doing so, a student demonstrates that they:
+
<BR>
* Are willing to commit some time during the Summer of Code application review period in order to prove that they can code C++ satisfactorily in a clean, well-documented style.
+
You also have to edit the following file to make spdif and/or hdmi work properly:
* Can effectively navigate the XBMC codebase.
+
* Can communicate well with the XBMC development-team and community via the forum and IRC.
+
* Can accept feedback and revise code after review until it is suitable for inclusion in the main XBMC codebase.
+
  
:'''TIP!''' Do not be shy, speak your mind, and get involved with the public community!

 +
<div style="height: 32px; border: thin inset black; background: #E6E6FA">
 +
# sudo nano /etc/modprobe.d/alsa-base
 +
</div>
  
'''Frequent Objection #1:''' "''But I don't have time to do a qualification task!''" Then how do we know you will have time to work on your task during the summer? The qualification tasks are selected to be fairly trivial by XBMC standards and should not be too difficult for a prospective XBMC contributor. If they are too difficult, maybe XBMC is not the project for you. Also, be encouraged by the fact that the application review period comes after the application submission deadline; i.e., you can work on a qualification task after you submit an application to XBMC. But you will not be considered for an GSoC project slot unless you have satisfactorily completed a qualification task.

'''Process:''' If you are truly interested in applying for XBMC's Summer of Code and, by extension, interested in working on a qualification task, the first step is to register a XBMC Community Forum Account, a SourceForge.NET Account and a XBMC Wiki Account (plus apply to get 'ninja status' for the Wiki by contacting a Team-XBMC member), and then publicly indicate that your interest and which project you plan to work on.

:'''Legacy Tasks''' - There is a growing back-log of 'interesting patches' and 'bug-reports' for XBMC on our patch-tracker and our bug-tracker which are both hosted on the XBMC SourceForge.net project site. Many of the patches have been abandoned by the original submitter, thus now requires volunteers to take the initiative to clean up each patch to the satisfaction of the project leaders and resubmit it for new review, so that it can be approved for SVN inclusion. As for the bugs, please try to fix enough bugs to show of your skill. See:
+
For some reason, the driver snapshot for ALSA 1.0.19 is not always downloading properly; in this case you have to run the script again. To check whether the driver upgraded or not:

Revision as of 17:06, 20 March 2009

The purpose of this guide is to give a hand to new XBMC users, who want to build a Linux based, dedicated HTPC (Home Theater PC), a true living-room media center computer, but don't have any knowledge and experience in the Linux world.

You always have the chance to try XBMC Live to test/demo XBMC Media Center, but if you want to have more control and more customization possibilities, than a Linux installation like in this guide is more suitable.

Contents

1 Introduction

This is a real step-by-step guide, I hope everybody can follow and walk through the whole installation procedure. The guide is based on either Ubuntu 8.04 (Hardy Heron) or 8.10 (Intrepid Ibex) as a platform, start with a minimal install and only install the needed components at the top of that.

On the face of it, maybe seems very lengthy process, but you will feel shorter while you follow it.

Please note:

  • The guide is for using XBMC on a dedicated HTPC, so there is no window manager and/ or any additional applications installed.
  • You need minimum 4GB size Flash drive or harddisk drive to install on.
  • Since you will use this PC only as a media center. I therefor assume that you use digital audio pass-through (S/PDIF or HDMI) to a receiver/amplifier with built-in Dolby Digital (AC3) decoder, and hence I choose NOT to install the dependency libraries for PulseAudio and compile XBMC later without PulseAudio support.

You will get:

  • A dedicated HTPC which auto-boots directly to XBMC Media Center.
  • Latest XBMC SVN version.
  • Updated ALSA (audio) driver.
  • Updated VIDEO (graphics) driver.
  • LIRC (Microsoft MCE Remote will work out-of-the-box, however if you have any other remotes and/or LCD displays then you are on your own to solve the individual LIRC and LCDproc issues).
  • Suspend/resume (works perfectly on for example ASUS P5N7A-VM motherboard with Intrepid).

Known issues:

  • Installations based on Intrepid having some performance issues, due to unidetified reason. You can read more on that here.
  • You might have some difficulties with suspend/ resume on Hardy based installation

2 Preparation

FIRST STEP

Download and burn Ubuntu Hardy or Intrepid mini.iso (according to your platform preference) from here:
https://help.ubuntu.com/community/Installation/MinimalCD

Please be aware, if you are installing a full Ubuntu system with GDM, then the guide will not fully work!

Now perform a default install.

  • When asked during the installation, please set „xbmc” as username and password at the account creation.
  • At the end, when you have to choose from the optional components, check only „OpenSSH” to be able to access your HTPC remotely via SSH.

Apparently there seems to be an issue with Intrepid installer. If you are using flash drive, it's not installing GRUB for some reason.
This is only affect Intrepid, and only when you are installing it onto a flash drive.

To handle this, you have to options:

  1. Either install Hardy(Ubuntu 8.04) mini.iso first, which is installing GRUB correctly, then right after that, install Intrepid mini.iso over the same flash drive. It will reformat the drive, but GRUB will stay alive on the drive.
  2. Second option is that right after Intrepid mini installation, boot up Intrepid mini.iso from the CD again, choose rescue mode, and there you will find an "install GRUB" option.

After you’ve done, boot it up, then use an SSH application (e.g. putty) to log in remotely from your desktop, using the above created username and password. This way, you will be able to copy/ paste all the steps below. Alternatively you can use console on the htpc too, but then you will have a hard time type in everything.

So once you logged in:


First of all, update the repositories, and install all prerequisites:

NEXT STEP

# sudo apt-get update

NEXT STEP Hardy - Skip this and jump to NEXT STEP Intrepid, if you are installing Intepid

# sudo apt-get --purge autoremove -y nvidia-kernel-common linux-restricted-modules-generic linux-restricted-modules-common linux-restricted-modules-2.6.24-23-generic

NEXT STEP Hardy - Skip this and jump to NEXT STEP Intrepid, if you are installing Intepid

# sudo apt-get install -y linux-headers-generic localepurge subversion make g++ gcc gawk pmount libtool nasm automake cmake gperf unzip bison libsdl1.2-dev libsdl-image1.2-dev libsdl-gfx1.2-dev libsdl-mixer1.2-dev libsdl-sound1.2-dev libsdl-stretch-dev libfribidi-dev liblzo-dev libfreetype6-dev libsqlite3-dev libogg-dev libasound-dev python-sqlite libglew-dev libcurl4-gnutls-dev x11proto-xinerama-dev libxinerama-dev libxrandr-dev libxrender-dev libmad0-dev libtre-dev libogg-dev libvorbis-dev libmysqlclient15-dev libpcre3-dev libdbus-1-dev libhal-dev libhal-storage-dev libjasper-dev libfontconfig-dev libbz2-dev libboost-dev libfaac-dev libenca-dev libxt-dev libxmu-dev libpng12-dev libjpeg-dev mesa-utils wget zip curl hal build-essential linux-headers-`uname -r` xorg pm-utils

NEXT STEP Intrepid

# sudo apt-get install -y localepurge subversion make g++ gcc gawk pmount libtool nasm automake cmake gperf unzip bison libsdl1.2-dev libsdl-image1.2-dev libsdl-gfx1.2-dev libsdl-mixer1.2-dev libsdl-sound1.2-dev libsdl-stretch-dev libfribidi-dev liblzo-dev libfreetype6-dev libsqlite3-dev libogg-dev libasound-dev python-sqlite libglew-dev libcurl4-gnutls-dev x11proto-xinerama-dev libxinerama-dev libxrandr-dev libxrender-dev libmad0-dev libtre-dev libogg-dev libvorbis-dev libmysqlclient-dev libpcre3-dev libdbus-1-dev libhal-dev libhal-storage-dev libjasper-dev libfontconfig-dev libbz2-dev libboost-dev libfaac-dev libenca-dev libxt-dev libxmu-dev libpng12-dev libjpeg-dev mesa-utils wget zip curl build-essential linux-headers-`uname -r` xorg pm-utils

During the installation of the packages, there will be a popup window to choose your locale languages to let "localepurge" know which locales not to remove in further installations. I would suggest to keep all en_us (3 all together) and your own country locales (again should be 3) as well. Localepurge will save you some space with removing unneccessary languages.

3 Upgrading ALSA (sound driver) to the latest version

I have modified the ALSA upgrade script (available at Ubuntuforums), and now it is working with only “-di” option in our case here (Also on ASUS P5N7A-VM).

To download and use the script:

NEXT STEP

# wget http://217.20.138.65/xbmc/AlsaUpgrade-1.0.x-rev-1.16.sh

NEXT STEP

# chmod a+x AlsaUpgrade-1.0.x-rev-1.16.sh


NEXT STEP

# sudo ./AlsaUpgrade-1.0.x-rev-1.16.sh -di

If you are on Intrepid, you have to add the user created at installation to the „audio” group (you don't need to do that in case of Hardy).

NEXT STEP

# sudo usermod -a -G audio xbmc 

(Please note: replace „xbmc” with username you installed with)


You also have to edit the following file to make spdif and/or hdmi work properly:

NEXT STEP

# sudo nano /etc/modprobe.d/alsa-base

and add this line to the end:

options snd-hda-intel model=6stack-dig


reboot the computer:

NEXT STEP

# sudo reboot

For some reason, the driver snapshot for ALSA 1.0.19 is not always downloading properly; in this case you have to run the script again. To check whether the driver upgraded or not:

NEXT STEP

# more /proc/asound/version

If you see driver version 1.0.19 here, you can continue, but it's shows 1.0.17 as driver version, then you have to repeat the last 3 step (upgrade, reboot, check).

If it’s OK, then you can delete the just downloaded ALSA source to free up some disk space:

NEXT STEP

# sudo rm -r /usr/src/Alsa-1.0.19/

Now run alsamixer:

NEXT STEP

# alsamixer

Navigate right with cursor keys until IEC958 and unmute all three of them (IEC958) with „M” key. You should see in case of all three IEC958 a „00” in green background. Press „ESC” to quit from alsamixer.

4 Update Video driver

4.1 Nvidia

(For Ati owners: jump to #Ati)

NEXT STEP

# wget ftp://download.nvidia.com/XFree86/Linux-x86/180.37/NVIDIA-Linux-x86-180.37-pkg1.run

NEXT STEP

# sudo sh NVIDIA-Linux-x86-180.37-pkg1.run

In the nvidia installer: accept the License agreement, choose „YES” for „No precompiled kernel interface...”, choose „OK” for „No matching precompiled kernel interface...”, than choose „YES” to update X configuration file, than finally „OK” again at the end.

Now you can delete Nvidia installer:

NEXT STEP

# rm NVIDIA-Linux-x86-180.37-pkg1.run

4.1.1 xorg.conf configuration (Nvidia)

If you want your Xorg autodetect the native resolutions from EDID and want to use 24p you have to replace your xorg.conf with this (not guaranteed to work, but should with newer Nvidia cards):

NEXT STEP

# sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

NEXT STEP

# sudo wget http://217.20.138.65/xbmc/xorg.conf -O /etc/X11/xorg.conf

(To continue click on: #Download, compile, and install XBMC from source (skip section Ati))


4.2 Ati

NEXT STEP

# sudo apt-get install -y cdbs fakeroot dh-make debhelper debconf libstdc++5 dkms

NEXT STEP

# wget http://www2.ati.com/drivers/linux/ati-driver-installer-8-12-x86.x86_64.run

NEXT STEP

# sudo sh ati-driver-installer-8-12-x86.x86_64.run --buildpkg Ubuntu/intrepid

NEXT STEP

# sudo dpkg -i xorg-driver-fglrx_8.561-0ubuntu1_i386.deb fglrx-kernel-source_8.561-0ubuntu1_i386.deb fglrx-amdcccle_8.561-0ubuntu1_i386.deb

NEXT STEP

# rm ati-driver-installer-8-12-x86.x86_64.run  *.deb

4.2.1 xorg.conf configuration (Ati)

Will be discussed later, stay tuned


5 Download, compile, and install XBMC from source

NEXT STEP - This is the main trunk, skip to the following step, if you want to use vdpau

# svn checkout https://xbmc.svn.sourceforge.net/svnroot/xbmc/branches/linuxport/XBMC

In case of Hardy, you will get a certificate warning, accept it permanetly by pressing „P”. Wait for downloading XBMC source files, might takes long time, depend on your Internet connection.

OPTIONAL STEP - In case you want to use vdpau branch, skip if you choosed the main trunk
You have to have vdpau compatible VGA vard for this with 512MB video ram at least!

# svn checkout https://xbmc.svn.sourceforge.net/svnroot/xbmc/branches/xbmc-vdpau/XBMC

In case of Hardy, you will get a certificate warning, accept it permanetly by pressing „P”. Wait for downloading XBMC source files, might takes long time, depend on your Internet connection.

NEXT STEP

# cd XBMC

Then configure, compile, and install XBMC:

NEXT STEP

# ./configure --prefix=/usr --disable-pulse

NEXT STEP

# make -j2 (Please note: use only „make”, if you don’t have a dualcore CPU)

This is again, can take quite some time, depending on your CPU speed.

NEXT STEP

# sudo make install


6 Autoboot to XBMC

WARNING!!! Do NOT follow this section unless you understand what EVERY step is actually doing. The original author hasn't thoroughly explained each step. If something goes wrong you WILL NOT be able to easily get to a normal desktop, so if you aren't 100% comfortable with recovering any and all issues in Linux from the command line, THINK TWICE!!! You can easily setup gdm to auto login and gnome to autostart XBMC.

NEXT STEP

# sudo wget http://217.20.138.65/xbmc/xbmc -O /etc/init.d/xbmc

NEXT STEP

# sudo chmod a+x /etc/init.d/xbmc

NEXT STEP

# sudo update-rc.d -f xbmc defaults

NEXT STEP

# sudo wget http://217.20.138.65/xbmc/runXBMC.sh -O /usr/bin/runXBMC.sh

If you not choosed "xbmc" as your user at the installation, you have to modify this file according to your username.

NEXT STEP

# sudo chmod a+x /usr/bin/runXBMC.sh

NEXT STEP

# sudo wget http://217.20.138.65/xbmc/setAlsaVolumes.py -O /usr/bin/setAlsaVolumes.py

NEXT STEP

# sudo chmod a+x /usr/bin/setAlsaVolumes.py

NEXT STEP

# sudo dpkg-reconfigure x11-common

And choose "anyone" to run X. Leave the other question on default.


7 Install Lirc

I've found MS MCE Remotes, listed here: http://www.mythtv.org/wiki/MCE_Remote, are plug & plays, working out of the box. I also found, that there're remotes out there, which instalation are a real pain. The choise is yours. If you have one of the above mentioned MS MCE remotes, the installation is that simple:

NEXT STEP

# sudo apt-get install -y lirc

And follow the wizard.


8 Power Management

To be able to control power management (suspend, shutdown, reboot) from within XBMC, you have to modify PolicyKit.conf to grant privilegies to your user for power management. There is a preprepared PolicyKit.conf for this, you can get it by:

NEXT STEP

# sudo wget http://217.20.138.65/xbmc/PolicyKit.conf -O /etc/PolicyKit/PolicyKit.conf

Please note: if you installed your system with username other than "xbmc" at the begining, you have to modify that in the file.


If you wish to enable CPU scaling, install the required packages as the following, but don’t forget to enable it in the BIOS as well.

NEXT STEP

# sudo apt-get install powernowd


9 Install Splash

You may want to have a look at du-duke's fantastique splash screens. You can check these here: http://du-duke.blogspot.com/ You can download your choice below.

NEXT STEP

# sudo apt-get -y install usplash libusplash-dev

NEXT STEP Hardy - Skip this and jump to NEXT STEP Intrepid, if you are installing Intepid

# sudo apt-get -y install usplash-theme-ubuntu

NEXT STEP Hardy - Skip this and jump to NEXT STEP Intrepid, if you are installing Intepid
CHOICE 1 - Downloading spinner-blue

# sudo wget http://217.20.138.65/xbmc/splash/usplash-spinner-hardy.so -O /usr/lib/usplash/usplash-theme-ubuntu.so

NEXT STEP Hardy - Skip this and jump to NEXT STEP Intrepid, if you are installing Intepid
CHOICE 2 - Downloading pulsating-logo

# sudo wget http://217.20.138.65/xbmc/splash/usplash-pulsating-hardy.so -O /usr/lib/usplash/usplash-theme-ubuntu.so

NEXT STEP Intrepid
CHOICE 1 - Downloading spinner-blue

# sudo wget http://217.20.138.65/xbmc/splash/usplash-spinner-intrepid.so -O /usr/lib/usplash/usplash-theme-ubuntu.so

NEXT STEP Intrepid
CHOICE 2 - Downloading pulsating-logo

# sudo wget http://217.20.138.65/xbmc/splash/usplash-pulsating-intrepid.so -O /usr/lib/usplash/usplash-theme-ubuntu.so

NEXT STEP

# sudo nano /etc/usplash.conf

and set your desired splash resolution, so inserting the following to here. (Please note: this is a FullHD example):

xres=1920
yres=1080

NEXT STEP

# sudo update-initramfs -u


10 Enable thermal monitoring

To install the necessary package:

# sudo apt-get install -y lm-sensors

Once lm-sensors installed, you have to run sensor detection to identify your sensors:

# sudo sensors-detect

There will be a lot of questions here, but you can answer by "enter" key to all of them, except the last question. So answer "enter" to all questions, until you see the the question "Do you want to add these lines automatically?" At here, you have to type "yes", then enter.

Reboot the computer:

# sudo reboot

After rebooted, check if the sensors are working:

# sensors -u

You should see the output of the sensors here.

10.1 XBMC CPU temp detection

To let XBMC detect your CPU temps provided by lm-sensors, you have to edit your advancedsettings.xml and insert the following:

<advancedsettings>
<cputempcommand>echo "$(sensors | grep "Core 0" | sed -e 's/[a-z]*..............\([0-9].\)\..*/\1/') C"</cputempcommand>
</advancedsettings>


10.2 XBMC GPU (nvidia) temp detection

To let XBMC detect your GPU temps provided by nvidia-settings, you have to edit your advancedsettings.xml and insert the following:

<advancedsettings>
<gputempcommand>echo "$(nvidia-settings -tq gpuCoreTemp) C"</gputempcommand>
</advancedsettings>



11 Enable eject button of your ODD

# sudo nano /etc/sysctl.conf

and uncomment (by deleting # from the begining of the line) the last line, so it will look like this:

dev.cdrom.lock=0


12 Reduce boot time

reduce GRUB waiting (~2 sec)

# sudo nano /boot/grub/menu.lst

Find the timeout (currently set to 3) and change this to 0


reduce the number of loaded vts (virtual terminal service)

By default, there're F1 through F7, we don't need that much for a HTPC, so we can remove most of them.

# sudo nano /etc/event.d/tty3

and comment out all the lines, using #. Repeat the above command for tty4-tty6, so at the end you've deactivated 3 vts's.


Enable concurrent booting (if you own a dual-core CPU)

# sudo nano /etc/init.d/rc

Find the line "CONCURRENCY=none" and change it to "CONCURRENCY=shell"


Disable unneccessary services
Install the necessary application

# sudo apt-get -y install sysv-rc-conf

And run it:

# sudo sysv-rc-conf

Navigate with your cursor keys, you can disable services by clearing X in each runlevel by "space" key.
You can disable the following services:

  • apparmor
  • dns-clean
  • fancontrol (unless you're using it)
  • pppd-dns
  • rsync


13 BIOS OEM Splash screen

Recent motherboards usually featured with the possibility to change to BIOS OEM logo. Below you can find a modified XBMC logo. The format and size of the picture has been modified to fit into the BIOS (ASUS P5N7A-VM), there is no guarantee to work with any other motherboard, but I guess it should work with all boards with newer AMI bioses.

BE AWARE! I take no responsibility if you brick your motherboard while playing with BIOS.

In case of ASUS, you can do it with MyLogo2, which is a bundled tool for your MB.

The aspect ratio of the picture is like this for purpose. When your BIOS displays it, it will stretch to fit to the screen. So this is made for 16:9 (not for 4:3, and nor for 16:10)
