Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Problem: Normal users aren't using the best graphics driver. I first noticed this playing Osmos from the HumbleBundle2, but I can observe it while running glxgears too. Maximised on a 1280x1024, glxgears averages a choppy 60 frames in 5 seconds, vs a smooth 300 frames every 5 seconds for root.

Here's some glxinfo:

jake@daedalus:~$ glxinfo | grep "renderer string"
OpenGL renderer string: Software Rasterizer
jake@daedalus:~$ sudo glxinfo | grep "renderer string"
[sudo] password for jake: 
OpenGL renderer string: Mesa DRI R300 (RV380 5B60) 20090101 x86/MMX+/3DNow!+/SSE2 TCL DRI2

I have the same problem even after rebooting (powering down, cycling surge protector). I followed the directions at the Ubuntu wiki for getting rid of fglrx, but no dice. What else can I do?

Hardware: Radeon x300 AMD Athlon 1.8 GHz 1.5 GB ram

I wonder if adding yourself to the 'video' group (I think) would help?

sudo adduser $USERNAME video

Can someone confirm the group name? Thx

Yes, the group is video. Adding myself to the group boosts my regular user's glxgears frame rate 500%. Thanks! –  djeikyb Jan 24 '11 at 23:21
    
@djeikyb, shouldn't this be a bug? Did you try and report it at Launchpad? Why are normal users restricted from taking advantage of the hardware capabilty? –  Oxwivi Feb 23 '11 at 12:37
    
It may be self-inflicted. I would have to test on a clean install on a real machine, not a vm. But yes, could be a bug. –  djeikyb Feb 23 '11 at 12:44
    
@djeikyb, I don't think it's self-inflicted since there's this video group to remove all restrictions. And if you reply, please add @Oxwivi - I hate to miss out on replies because I wasn't notified. –  Oxwivi Mar 1 '11 at 14:59
    
@Oxwivi Oh! Will do, didn't realise that's how comments work. Cool. –  djeikyb Mar 2 '11 at 3:59
