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
