I recently purchased and installed an AMD Sapphire R7 4GB 240. Ubuntu automatically switched to some Open-Source Drivers named Gallium 0.4 on AMD OLAND.
For some reason Steam is not able to launch anymore. I tried opening it from command line and this error came up:
Running Steam on Ubuntu 15.04 64-bit
STEAM_RUNTIME is enabled automatically
Installing breakpad exception handler for appid(steam)/version(1440016726)
libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi
libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
(Steam used to work properly)
I believe Steam was not able to find Official Drivers, since I did not install them, which I am unable to find. A DVD with those drivers was included, but it said "Windows XP,Vista,7,8". Not Mac or anything.
Is anybody who knows what am I doing wrong?
EDIT: I started it up with the help of irc.ubuntu.com with this article: https://wirejungle.wordpress.com/2015/01/09/how-to-fix-broken-steam-linux-client-with-radeon-graphics-driver-workaround/ ... but I can't start up any game at all
Second Edit: You can also tell me how to run games on Steam while running this following command:
LD_PRELOAD=/usr/lib/i386-linux-gnu/libstdc++.so.6 DISPLAY=:0 steam
EDIT 3: @SachinKamath told me to re-install Steam from the command line, after deleting Steam. (She was right, even though a Steam Launcher problem seems to appear)
But the following error appears if I run it on command line: Erm.. I got one problem..
