here is another one.

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.
(RS690M [Radeon X1200 Series])
Is it problem just with Firefox or other X applications show garbage instead of characters as well? What's your locale?
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"
Seems to be the same as 473895 .
