one screen shot showing corruption

some old session.

some taken from koji:

How reproducible:

Steps to Reproduce:
1. boot without any xorg.conf
2. start firefox
3. watch screen
Actual results:
corrupted display after a few web pages from old session is restored.

normal usage.

Xorg.0.log, no xorg.conf

Xorg.0.log, without xorg.conf.

The hardware is (should be somewhere in the log, just saving somebody looking it up):

VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series]

Recently the nomodeset situation seems to have changed, so I tried various combinations. There is no winners, and each of them all have their own problems:

radeon + EXA: tearing while scrolling, and most recently, font/screen corruption when firefox is used. (bug 473815)

radeon + XAA: need to boot with nomodeset, or it goes into a black screen instead of GDM. (bug 464896 ?)

radeonhd : no xvideo (bug 473819)

For general use, radeon + XAA is the best at the moment.

Is it problem just with Firefox or other X applications show garbage instead of characters as well? What's your locale?
Comment 5 Hin-Tak Leung 2008-12-01 11:55:27 EST
It is the whole desktop going funny color (plus fonts garbage) - if it wasn't already 24-bit/true-color display I would say it looks like the good old days with 8-bit display, when the palette has gone wrong. 

$ export | grep LANG
declare -x GDM_LANG="en_GB.utf8"
declare -x LANG="en_GB.utf8"
