           Summary: garbled screen with X.org 7.3 (ati driver 6.7.192)
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: mccope at googlemail.com
         QAContact: xorg-team at lists.x.org


After starting X.org (with xserver 1.4 & ati drivers 6.7.192) the display
doesn't appear correctly on my laptop with an ATI Radeon RV350 M10 graphics
card.

The screen shows a fuzzy 'cloud' of colour rather than a clear image (see
attached photos).  Everything is running properly though, just the display is
garbled.

If an external monitor is connected to the laptop the external monitor works
correctly, but the laptop panel remains fuzzy.

Also attached are copies of
lspci -vv
dmidecode
and 2 copies each of /etc/X11/xorg.conf, /var/log/Xorg.0.log, xrandr and xrandr
--verbose and get-edid - one for 7.2 where everything is working and one for
7.3 which has the problem and a diff file showing the changes between the two
sets of files
