Hi all,
I am trying to get DRI working on my matrox G450 in single-head mode,
but with no avail. The best I can manage is software rendering without
DRI, which is too slow for gaming (I want to try out some linux games).
I have the mga driver compiled (kernel 2.6.14) as a module and it loads
up at startup. Also I have the mga_drv.o and mga_hal.o drivers from the
matrox site. But I still get the following errors (during X startup):
No matching visual for __GLcontextMode with visual class = -1 (-1),
nplanes = 0
No matching visual for __GLcontextMode with visual class = -1 (-1),
nplanes = 0
No matching visual for __GLcontextMode with visual class = -1 (-1),
nplanes = 0
No matching visual for __GLcontextMode with visual class = -1 (-1),
nplanes = 0
No matching visual for __GLcontextMode with visual class = -1 (-1),
nplanes = 0
No matching visual for __GLcontextMode with visual class = -1 (-1),
nplanes = 0
No matching visual for __GLcontextMode with visual class = -1 (-1),
nplanes = 0
No matching visual for __GLcontextMode with visual class = -1 (-1),
nplanes = 0
If I try running glxinfo I get the following:
libGL warning: 3D driver claims to not support visual 0x23
libGL warning: 3D driver claims to not support visual 0x24
libGL warning: 3D driver claims to not support visual 0xffffffff
libGL warning: 3D driver claims to not support visual 0xffffffff
libGL warning: 3D driver claims to not support visual 0xffffffff

libGL warning: 3D driver claims to not support visual 0xffffffff
libGL warning: 3D driver claims to not support visual 0xffffffff
libGL warning: 3D driver claims to not support visual 0xffffffff
And If I try running any glx-enabled program, it will fail, the glxgears
program provides the following error:
libGL warning: 3D driver claims to not support visual 0x23
libGL warning: 3D driver claims to not support visual 0x24
libGL warning: 3D driver claims to not support visual 0xffffffff

libGL warning: 3D driver claims to not support visual 0xffffffff
libGL warning: 3D driver claims to not support visual 0xffffffff
glxgears: Error: couldn't get an RGB, Double-buffered visual.
Can anyone help me with this?? I can provide additional info if you
need (just ask, for things like xorg.conf file os lspci output).
Thanks,
Ognjen B
