Description John Waymouth 2004-09-12 10:48:11 UTC 
I've just migrated from XFree86 4.3.0 to X.org 6.8.0 to see how things look. 
While 2D acceleration worked perfectly in XFree86, it's horribly broken in
X.org.  My initial XDM screen looks horribly corrupted, with only a vague
outline of the login box visible.  After logging in, some things seem to be OK,
but other areas of the screen are corrupted.  It seems like areas involving
direct pixel plotting by an application work, whereas line-drawing and such
fail.  Scrolling in firefox is broken, only some parts of the browser update. 
All in all, pretty much nothing works right, and, of course, when I turn off
acceleration, everything is slow as hell.  This seems to be independent of
bit-depth.

I have this same problem using xorg-6.8.1. Any known workarounds?
Comment 2 Egbert Eich 2005-03-03 06:39:20 UTC 
Have you tested 6.8.2?
Comment 3 Egbert Eich 2005-03-03 06:43:56 UTC 
*** Bug 1379 has been marked as a duplicate of this bug. ***
Comment 4 Alan Hourihane 2005-04-02 15:18:38 UTC 
Asking one more time, have either of you tried 6.8.2 ?
Comment 5 John Waymouth 2005-04-02 15:24:22 UTC 
Sorry, must have missed the previous question.  No, I haven't tried 6.8.2 on
that machine because the screen died.  Sorry I can't help you track this down
anymore.

I have not had a chance yet. The machine I have that has this chipset is my system at work, and I've 
worked around this issue by using an external video card. I'll try to make time this coming week to rip 
out the external card & try this chipset. I'll be testing this on Ubuntu's XOrg, and I don't know if they 
apply any external patches.
Comment 7 Alan Hourihane 2005-06-28 02:18:31 UTC 
Closing. Believed to be fixed in 6.8.2. Re-open if the problem persists after
upgrading.
