We're seeing some weird problems with the R128 driver from 7.1
running on Dell C600 laptops:
One symptom the problem is that XSetWindowbackground(window, None)
is not working - instead of not clearing the background on exposes,
the background is being cleared to black.
Another symptom is that every time that the background is set,
there is a flash to black.
It is very difficult to see this damned flash everyday!
Steps to Reproduce:
1. Run 7.1 on a Dell C600 (perhaps other Rage Mobility based machines)
What happened to 2 & 3? ;o)
Is this a Mobility M3 or M4? Can you attach X server log from after the
weirdness happens, and also a copy of your config? I do not have a laptop
to test with, but I have an M3 engineering sample. If it is an M4, does
anyone around there have an M3 they can reproduce it on? I have an M4
as well but can't use it (AGP 4x only).
Fire me any other info you think might help also. TNX
uh... I don't know....

ooh - ooh!

If I run the X server in 24bit mode there is no more flicker! I am saved! No
more seizures! That should narrow the problem down to an even smaller code set
If you have DRI enabled, divide your RAM by 6. That is approximately how
much RAM is available for one screen. DRI needs lots of RAM + RAM for textures
and pixmaps, etc..
Future releases of Xconfigurator at some point will have a checkbox to enable
or disable DRI, and will calculate the maximum resolution available with DRI
Oh, I almost forgot, I need your config file and X logs still...

This problem has been fixed for a while now, and should not be present in
the current release (8.0) of Red Hat Linux. I've tested a sample board that
ATI has provided, and it works ok.
