=====Hardware acceleration with ATI open source drivers=====
// Tested on Devuan Jessie alpha2 64-bit. //

For the 3D (OpenGL) acceleration features of the ATI open source drivers it is required to install a non-free firmware package.

  - Edit /etc/apt/sources.list by adding the suffix 'contrib non-free' next to 'deb <URL> jessie main'. Example: <code>deb http://nl.mirror.devuan.org/merged/ jessie main contrib non-free</code>
  - Update the list of packages: <code>apt-get update</code>
  - Install the non-free firmware package: <code> apt-get install firmware-linux-nonfree</code>
  - Restart the system.
  - To check for success either start a 3D program/game or install the mesa-utils and test with glxinfo:<code>apt-get install mesa-utils
glxinfo | grep OpenGL</code>
  - The output should show an "OpenGL renderer string" mentioning the installed ATI graphics adapter and should not contain 'llvmpipe'. Example:<code>OpenGL renderer string: Gallium 0.4 on AMD RV730</code>

=====Install Steam=====
// Tested on Devuan Jessie alpha2 64-bit. //

The current (as of 2015-06-30) version of Steam needs some manual configuration to get it to work on Devuan.

  - Add MultiArch support for i386 architecture (on x86_64) and update the package list:<code>dpkg --add-architecture i386
apt-get update</code>
  - Install prerequisites:<code>apt-get install libgl1-mesa-dri:i386 libgl1-mesa-glx:i386 libc6:i386 curl zenity zenity-common libcurl3 libwebkitgtk-3.0-0</code>
  - Download steam_latest.deb from http://store.steampowered.com/about/.
  - Install steam_latest.deb:<code>dpkg -i steam_latest.deb</code>
  - Starting Steam now will only show:<code>
Setting up Steam content in /home/bas/.local/share/Steam
Running Steam on devuan 1 64-bit
STEAM_RUNTIME is enabled automatically
Installing breakpad exception handler for appid(steam)/version(0)
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast</code> // At which point you should kill it with Ctrl+C. //
  - This is caused by the libstdc++ library shipped with Steam not being compatible with Devuan. To fix:<code>
cd ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu
mv libstdc++.so.6.0.18 libstdc++.so.6.0.18.remove.by.user
rm libstdc++.so.6
</code>
  - Now start steam and allow it do download it's updates. When Steam is again at the 'libGL error: failed to load driver: swrast' point kill (Ctrl+C) it and again rename the libstdc++ files:<code>
cd ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu
mv libstdc++.so.6.0.18 libstdc++.so.6.0.18.remove.by.user
rm libstdc++.so.6
cd ~/.local/share/Steam/ubuntu12_32/steam-runtime/amd64/usr/lib/x86_64-linux-gnu
mv libstdc++.so.6.0.18 libstdc++.so.6.0.18.remove.by.user
rm libstdc++.so.6
</code>
  - Start steam. It should now work and allow you to login.

=====Install nVIDIA drivers=====

  - Stop Slim: <code>/etc/init.d/slim stop</code>
  - Login as root.
  - Start the driver installation:<code>sh NVIDIA-Linux-x86_64-358.16.run</code>
  - Go through the wizard for driver installation. // Don't forget to register the driver with DKMS. //
