Description David Mason 2001-04-25 18:17:23 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.2-2 i686; en-US; 0.8) Gecko/20010217


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!


Reproducible: Always
Steps to Reproduce:
1. Run 7.1 on a Dell C600 (perhaps other Rage Mobility based machines)
2.
3.

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

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
too :)

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
enabled.

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.
