Last modified: 2007-11-30 17:11:28 EST
Description of problem:
After upgrade to xorg-x11-drv-ati-126.96.36.199-4.cvs20060322.i386.rpm on
an IBM T41 laptop with a Radeon display card, as reported in lspci:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LW
[Radeon Mobility 7500]
the display was completely garbled / unreadable .
Downgrading to xorg-x11-drv-ati-188.8.131.52-4.i386 and restarting X fixed the
problem, with the same xorg-x11-server-Xorg-184.108.40.206-2 server.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
unusable garbled display
I'm attaching the X -probeonly logs
A) From the driver causing the garbled display:
B) From the driver providing the usable display:
and my xorg.conf file.

'startx' log after downgrading to xorg-x11-drv-ati-18.104.22.168-4 with OK display
Clarification of "Garbled":
With xorg-x11-drv-ati-22.214.171.124-4.cvs20060322, the display is initially clear
and the 'X' cursor shows OK until the first image is displayed (ie. the KDE/GNOME
splash screen). Then it looks like every image is repeated horizontally across
the screen at horizontal increments of around 10 pixels - this is repeated for
every icon shown when the desktop appears.
This bug is now fixed with xorg-x11-drv-ati-126.96.36.199-4.cvs20060404 - thanks !
