Unfortunately, even with working DRI you won't be seeing any desktop
effects. Those effects require very specific off-screen rendering
functionality of which Mach64 cards are not capable. You will, however, see
a fairly drastic boost in more 'general' OpenGL functionality.
Your situation brings up another reason why this bug isn't likely to be
closed anytime soon: Mach64 DRI seems to be hit or miss with results being
insignificant to most users.
As for additional tips... no clue, really. In my /etc/X11/xorg.conf I have
the following changed, and I really have no clue if it makes a difference
(meaning I'm too lazy to test, sorry!):
(In Section ServerLayout make sure the following is commented out if it
exists)
#Option "AIGLX" "False"
(The following section may need to be added if it is not present, but I
believe it's there by default in newer Ubuntus)
Section "DRI"
Mode 0666
EndSection
For more rigorous (and involved) instructions, check for earlier posts from
me in the bug notes. There are instructions for replacing libGL in the case
that it is the culprit. However, I really am hoping the DRM modules were
all that needed to be compiled...
