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

can you try again with ati git master?

Compiling the drivers from git today works! (see above Xorg.0.log) The only resolution available is the panel's native resolution (this is ok, because it's the only one I use). Googling on the panel's name (Samsung LTN150P1-L02) suggests that the EDID data it returns is corrupt so this is probably the root cause of the problem.
It's not the edid as your laptop doesn't provide one for the panel. It was a issue with how the plls were programmed.
