I've gotten optirun and primusrun to work with glxgears and also with launching Counter-Strike: Global Offensive(csgo) straight from the executable file:

~/.steam/steam/steamapps/common/Counter-Strike Global Offensive/csgo_linux

but that launches the game in insecure mode so I'm unable to play on VAC (Valve anti cheat) servers. but if I try to launch the game from steam itself it doesn't work. I've tried every launch option I've come across amongst these are the regular optirun %command%, primusrun %command%, LD_PRELOAD="libpthread.so.0 libGL.so.1" __GL_THREADED_OPTIMIZATIONS=1 optirun %command%

Any other suggestions? All answers appreciated!

  • Define "doesn't work": It does not start, you know for sure that it is using the intel card or you are just getting a low performance? – dan_s Jun 9 '15 at 9:48
  • Doesn't work means it doesn't start at all. Steam says I'm in-game for about a second, then nothing happens. If i don't have any launch options it works, but the nvidia card is not in use (Checked with lshw) – Jonas Natten Jun 9 '15 at 10:38
  • Try running this command in the console and see if you get any errors: primusrun steam steam://rungameid/730 (730 is the ID for CS:GO) – dan_s Jun 9 '15 at 10:55
  • That made the game launch (if i remove the launch options from steam), but it still isnt using the nvidia graphics, like it does with glxgears. The only thing i get in the terminal i launch it from is: Running Steam on ubuntu 15.04 64-bit STEAM_RUNTIME is enabled automatically. If it is possible i could also live with disabling the intel graphics and using only the nvidia card. – Jonas Natten Jun 9 '15 at 15:44

I've had exactly the same problem 1 hour ago. To fix it, edit the file .steam/steam/steamapps/common/Counter-Strike Global Offensive/csgo.sh

Before the two lines that start with ${DEBUGGER} "${GAMEROOT}"/${GAMEEXE} you must add "primusrun" (maybe only one line is necessary, didn't tested):



primusrun ${DEBUGGER} "${GAMEROOT}"/${GAMEEXE} "$@"

Then remove the CounterStrike's launch options in steam and launch the game normally from Steam. It should launch on the GPU

  • This seems to work perfectly! I also added vblank_mode=0 to disable the vsync. Thanks a lot! – Jonas Natten Jun 20 '15 at 21:27
