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
uh... I don't know.... $scanpci pci bus 0x1 cardnum 0x00 function 0x0000: vendor 0x1002 device 0x4c46 ATI Rage 128 Mobility LF
ooh - ooh! ATI Technologies Inc Rage Mobility M3 AGP 2x (rev 02)
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.
