Hi
I don't know much about 3D or the ATI graphics cards, but I can tell you how I got the
DRI CVS to work with my ATI 9000 Pro card (ID 4966).
First I took the source to XFree86 4.2.0 compiled and installed, I then checked out
the latest DRI source from CVS. Applied my patch, then make World, make install. I
then had to do "chmod -R ugo+rX /usr/X11R6" to get the permissions right on the
drivers. Then in the DRI CVS tree I went into
xc/programs/Xserver/hw/xfree86/os-support/linux/drm/kernel did a "make -f
Makefile.linux" and copied the radeon.o to /lib/modules/x.y.z/kernel/drivers/char/drm
and ran "depmod -a". I then installed agpgart kernel module followed by radeon, then
started X. Then when I run glxgears it works great.
To get the DRI permissions set right add the following to the bottom of your XF86
Config file
Section "DRI"
Mode 0666
EndSection
Problems:
I do have problems with the 3D support, as I said it is not perfect. I use the 3D to
run WarCraft III under Wine in opengl mode, I haven't tried any other programs. The
problems I get are, if I try to move the window in which Warcraft starts it will
completely lock up the graphics card. The only way of getting any picture back on the
monitor is by rebooting. Also some of the 3D objects don't always appear properly and
can partially appear then disappear, I have also seen some flashing colors. However,
This isn't significant enough to make the game unplayable, in fact it is still very
playable.
