== <big>'''Installation and configuration of XBMC on Ubuntu based OS with AMD HD Graphic (tested with Zotac AD02 and AD10)'''</big> ==
[[Category:Kodi]]
 
[[Category:Index]]
=== '''The Goal:''' ===
Installing and configuring all the necessary to get a fully functional, stable and great XBMC media center on AMD Plateform using prorietary ATI driver and Hardware acceleration.
 
=== Software: ===
 
This configuration guide has been tested under Ubuntu based OS running 11.10 TLS and 12.04 TLS (desktop versions of Xubuntu and Lubuntu)
 
=== Hardware: ===
 
This configuration guide has been tested on Zotac AMD Based HTPC: ZOTAC AD02 and ZOTAC AD10
 
<br>These two HTPCs are quite the same; One major difference is the included and optional USB IR receiver for Zotac AD10, associated with its nice MCE remote control.
 
<br>Also, only the Zotac AD02 has an SPDIF output to serve Digital sound, digital sound for Zotac AD10 will be achieved using HDMI ouput
 
<br>Both of them are embedded with an AMD E350 CPU with ATI Radeon HD able to deal with 1080p video and 5.1 Digital audio :-)
 
<br>'''Zotac AD02 Model :'''
AMD E-350 APU Platform (dual-core) (1.6 GHz)
AMD Radeon™ HD 6310

'''Zotac AD10 Model :'''
AMD E-350 APU Platform (dual-core) (1.6 GHz)
AMD Radeon™ HD 6310

=== Step 1: Install your system ===
 
<br>First choose your Ubuntu version to install.
This guide will only be fully applicable with an Ubuntu based version.
 
<br>I will not cover the OS installation itself as there is a lot of tutorials on this subject and installation is enought easy right now.
 
<br>I do not recommend using Ubuntu classic version as it provides by default a very resource consuming interface (Unity) and has a lot of problems and bugs running ATI proprietary driver!
 
<br>As far as I know and as far as I tested, the only Ubuntu bases distributions with absolutely no issue with the ATI proprietary driver are:
 
<br>* Xubuntu : Ubuntu based version with XFCE desktop
<br>* Lubuntu : Ubuntu based version with LFCE desktop
 
<br>I would recommend Lubuntu in the case of a XBMC dedicated system (but that’s all my personal choice and therefore i prefer to use Xubuntu) as it has a really low resource consuming desktop interface.
 
<br>'''NB:'''
 
You may also want to choose a minimal Ubuntu installation and then only run an Xserver that will directly start XBMC interface.
This guide will still be approximately applicable in this case.
 
<br>'''I did not choose this option for different reasons:'''
 
* No desktop interface to deal with system, files and so on (even if often prefer the command line, 2 possibilities are always betters than one!)
* No Web browser
* No graphical tool to manage Networks connections, etc…
* No access to AMD ATI graphical configuration manager, so no way to simply change resolution, brightness, contrast and so on
 
'''Installation recommendations:'''
 
'''3 partitions :'''
 
* A first partition for the root system ( / )
* A second partition for home (/home)
* A small Swap partition (1 or 2 GB will largely be enough, a such system is not expected to really swap in normal conditions)
 
'''Other:'''
 
* Install Third party softwares (mp3 and so on)
* In the installation Software, use “xbmc” as a the login
* Activate autologin for the user "xbmc"
 
=== Step 2: Ensure your system is up to date and upgrade if required ===
 
<pre>
sudo apt-get update
sudo apt-get upgrade -y
sudo dist-upgrade –y
sudo reboot
</pre>
 
=== Step 3: Install some requirements ===
 
<pre>
sudo apt-get install ssh python-software-properties udisks upower xorg alsa-utils mesa-utils git-core
librtmp0 lirc libmad0 lm-sensors lib32gcc1 libc6-i386 dkms
</pre>
 
<br>NB : For lirc, when wizard asks you to choose your hardware in our case we will configure it later so you can choose none...
If you already know how to configure lirc and your hardware you may want to choose the right one.
 
=== Step 4: Install ATI proprietary driver (required for XVBA Hardware acceleration) ===
 
* Get the driver from AMD Site (same file for both 32/64 Bits):
 
http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx
 
* Build Packages:
 
<pre>
sudo sh ./amd-driver-installer-*-x86.x86_64.run --buildpkg
</pre>
 
NB: I you are missing some requirements to build packages, a graphical apt-get install will automaticaly appear
and install requirements, just valid and proceed and package building will continue
 
Packages will be built in current directory and exit.
 
* Install packages:
 
<pre>
sudo dpkg -i fgl*.deb
</pre>
 
* Create xorg configuration files
 
<pre>
sudo aticonfig -initial -f
sudo aticonfig -sync-vsync=on
</pre>
 
Optionnal and not destructive: Disable underscan (black borders)
 
<pre>
sudo aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0
</pre>
 
* Reboot
 
<pre>
sudo reboot
</pre>
 
=== Step 5: Proceed with XBMC installation using pre-compiled packages built for ATI ===
 
This procedure will add a ppa containing pre-compiled XBMC stable Eden version with XVBA support and install XBMC:
 
* Add the ppa:
 
<pre>
sudo add-apt-repository ppa:wsnipex/xbmc-xvba-eden
</pre>
 
Press enter to valid adding this ppa
 
* Update and install:
 
<pre>
sudo apt-get update
sudo apt-get install xbmc xbmc-bin
</pre>
 
=== Step 6: XBMC nice level ===
 
* Allow xbmc user to change its nice level:
 
edit /etc/security/limits.conf
add the following line at the end of the file
 
<pre>
xbmc            -      nice          -1
</pre>
 
=== Step 7: First start of XBMC and base configuration ===
 
'''Open XBMC and proceed with first settings:'''
 
* Open XBMC
 
* In Appearance / skin, I recommend “NEON” (again my personal choice!)
 
* In Appearance, adapt your language if required
 
[[File:Screen1.png]]
 
* In System->Settings->System->Video Settings:
 
Vertical Sync: Always on
 
[[File:Screen2.png]]
 
* In System ->Video->Playback:
<br>XVBA: On
<br>Adjust Refreshrate to match video: On
<br>Sync Playback to Display: On
<br>Sync Method: Video Clock (Drop/Dupe)
 
[[File:Screen3.png]]
 
* Exit XBMC
 
=== Step 8: Optimizing XBMC CPU use ===
 
Enable Dirty Region Rendering (drastically reduces CPU load on XBMC idle) and DDS Fanart
NOTE: do not do this as root or with sudo. this file must belong to your normal xbmc user
 
create: ~/.xbmc/userdata/advancedsettings.xml
 
<advancedsettings>
  <loglevel hide="false">0</loglevel>
  <gui>   
    <algorithmdirtyregions>1</algorithmdirtyregions>
    <visualizedirtyregions>false</visualizedirtyregions>
    <nofliptimeout>0</nofliptimeout>
  </gui>   
  <cputempcommand>sensors|sed -ne "s/temp1: \+[-+]\([0-9]\+\).*/\1 C/p"</cputempcommand>
  <gputempcommand>/usr/bin/aticonfig --od-gettemperature | grep Temperature | cut -f 2 -d "-" | cut -f 1 -d "." | sed -e "s, ,," | sed 's/$/ C/'</gputempcommand>
</advancedsettings>
 
=== Step 9: Configuring Digital Audio ===
 
<br>You will certainly want to get Digital sound with your own Home Cinema, to get this working you have two possibilities depending on your hardware :
<br>
* Digital sound through SPDIF
* Digital sound through HDMI
 
<br>I will provide these two examples, you have to adapt this depending on your Hardware !
 
* Digital Audio with SPDIF on Zotac AD02
 
<br>As xbmc user, create a new file in your home: ~/.asoundrc
 
<pre>
pcm.dmixer {
    type dmix
    ipc_key 1024
    slave {
        pcm "hw:1,1"
        period_time 0
        period_size 1024
        buffer_size 8192
        #periods 128
        #rate 44100
        rate 48000
    }
    bindings {
        0 0
        1 1
    }
}
</pre>
 
<br>Restart XBMC, in Settings>System>Audio Output:
 
* Audio Output: Optical/Coax
* Speaker Configuration: 5.1
* Audio Output Device: Custom
* Custom Audio Device: plug:dmixer
* Passthrought Output Device: Custom
* Custom Passthrought Device: plug:dmixer
 
[[File:Screen4.png]]
 
* Digital Audio with HDMI on Zotac AD10
 
<br>As xbmc user, create a new file in your home: ~/.asoundrc
 
<pre>
pcm.dmixer {
  type dmix
  ipc_key 1024
  ipc_key_add_uid false
  ipc_perm 0660
  slave {
      pcm "hw:0,3"              #HDMI, defaults to 48000 kHz
      channels 2
      period_size 1024
      buffer_size 4096
  }
}
pcm.!default {
  type plug
  slave.pcm "dmixer"
}
</pre>
 
<br>Restart XBMC, in Settings>System>Audio Output:
 
* Audio Output: HDMI
* Speaker Configuration: 5.1
* Audio Output Device: Custom
* Custom Audio Device: plug:dmixer
* Passthrought Output Device: hdmi (alsa)
