Re: A Radeon and X question, probably not Debian specific
In your message of: 24 Jul 2002 23:22:23 +0200, you write:

Xscreensaver's gears does about 50 fps at its default size, 25 fps in
a maximized window, and 5 fps in full screen saved mode. I wish it
was software rendering, because then I would know what problem I have
to fix.
Everything seems to be working fine, if I swap the radeon
card with a matrox card, and change the driver line in XF86Config-4
from radeon to mga, everything works great. I have not tried the
radeon card in another machine, nor have I used it under Windows. 2d
performance is fine, and I otherwise have no X related problems.
