Comment 40 for bug 285250

This is an upsetting bug.

I have disabled dri as a workaround also.

I have Intrepid with Gnome (No Composition) and Arch with only Openbox (No Composition)

These are the "glxgears" rotations:

Arch:

415 frames in 5.0 seconds = 82.828 FPS
429 frames in 5.0 seconds = 85.618 FPS
425 frames in 5.0 seconds = 84.992 FPS

Ubuntu:

828 frames in 5.0 seconds = 165.505 FPS
864 frames in 5.0 seconds = 172.673 FPS
795 frames in 5.0 seconds = 158.900 FPS

For some reason though Ubuntu is almost double what Arch is.

I wouldn't care too much because I'm not really a gamer but the CPU fan is extremely loud at the moment and it never stops whirrring.

I get a few warnings every now and again about the CPU being too hot and performance is going to be capped.

If I enable acceleration with the 2.6.1 is also get: Failed to pin front buffer: Cannot allocate memory

Has anyone tried using xcompmgr instead of metacity or compiz composition?
