One thing I've noticed is that XFree86 4.0.3 is much more stable than
4.0.2, and that newer NVidia drivers are also far more stable than old
ones. I use an original GeForce I (but DDR). The 4.0.3 has a lot to do
with SMP cleanups (I use SMP). The one thing that I found was the real
show stopper is that I had to use the NVidia agpgart, and I had to
specify 2x AGP, not 4x. The 4x was a problem. But considering I've had
640x480 24/32 bit programs exceeding 300 frames per sec, I don't think
it is a problem. To specify 2x AGP with NVidia, within
/etc/X11/XF86Config-4, find Section "Device" for the nVidia hardware,
and add this (but be sure you are set to boot to console mode in case it
doesn't go right...you can escape from a respawning X11 server, but it
takes good timing):
Option "NvAgp" "2"
Mine reads:
Section "Device"
Identifier "nVidia Corporation|GeForce 256 DDR"
Driver "nvidia"
BoardName "Unknown"
Option "NvAgp" "2"
EndSection
And under lsmod I see these:
agpgart 14816 3 (autoclean)
NVdriver 659584 15 (autoclean)
(though I'm not positive, I do think probably the agpgart is the NVidia
version)
With the 2x AGP, I find it is difficult to crash X11 under OpenGL
(though I did recently come across a strange case that required
rearranging the order of setting up an OpenGL window...glClearColor()
had to be changed to a different location).
