I have a Rock Quaddra T64 with ATI x700 mobility gaphics and a 17" widescreen 1440x900 LCD screen (Samsung possibly).

I have had similar problems in boh Breazy and Dapper with blank screen on install. I tied switching to "vesa" drivers instead of the detected "ati" but this simply gave an error something like:

VESA :No matching modes
Screens found, but none have usable configurations

I eventuall found this and other similar bug reports so replaced the following line the "monitors" section in xorg.conf.

Option "DMPS"

to

Option "MonitorLayout" "LVDS"

Not sure if I needed to repalce the DPMS thing or leave it, but with the other line in palce I managed to get KDE running at 1024x768. I can set the resolution to 1440x990 but the screen then goes a bit weird and seems to wrap left to right.
