Thanks Mathieu!
This option does help somewhat with the 82845G chipset I have, but it's
not a correct answer.
With this option enabled, X will start after a cold boot and run fairly
well, but then the trouble becomes ending the X session. When you exit
X, the display is often left in a weird state with blurred, distorted
or displaced text as if the display never quite made it back in to text
mode properly.
On occasion, X will exit properly, but more often than not it leaves
the display in some weird state.
With the "AccelMethod" option you mentioned, a cold boot does allow me
to get X running on the first try, but exiting X, or restarting X just
doesn't work properly.
Shutting off the acceleration entirely with the "Accel" option has
basically the same effect as designating the "AccelMethod"
Option "Accel" "false"
Again, shutting off acceleration completely allows you to get X running
after a cold boot, but exiting X and/or restarting X typically results
in either a screwed up text mode, or a failed/incomplete start of X.
Is there anything else I could do to help fix this instability bug?
