Bug Description

Hardware: Targa Traveller 826, Mobility Radeon X700 (PCI-Express)

Software: Kubuntu Dapper Flight 3 i386, latest updates as of 09-Feb-2006.
xserver-xorg-driver-ati is at 1:6.5.7.3-0ubuntu1

Symptoms: Booting the system, all you get is a black screen where you'd expect the kdm login. Console works, though.

Examining the Xorg.log revealed that the x-server recognises the laptop's analog VGA port as primary display, but doesn't seem to come to grips with the built-in LCD. Obviously, kdm gets started on the VGA port, leaving the LCD black.

I'll attach the Xorg.0.log and Xorg.conf asap

Workaround: install fglrx drivers , that works.

X used to just work with Dapper Flight 2.

I manage to find a workaround to get this system going:

In xorg.conf the "Device" section has to look like this:

Section "Device"
Identifier "ATI Technologies, Inc. Radeon Mobility X700 (RV410 PCIE)"
Driver "ati"
BusID "PCI:1:0:0"
*Option "MonitorLayout" "LVDS, NONE"*
EndSection

The line I added is marked with the "*" symbols.

Using "LVDS, CRT" would create a kdm on the LCD with only VGA resolution, whereas the version used above correctly creates a 1280x800 display.
It seems the xorg.conf created during installation does not correctly reflect the hardware environment. If possible, some sort of Dual-Head configuration should be created that automatically detects if a monitor is connected to the VGA port or not. The LCD should always work.

I'll attach a second version of xorg.0.log to compare against.

This version uses the workaround described in the last comment, making kdm correctly start on the LCD.

The problem persists in Dapper Flight 5. I have added an upstream bug report that describes the same problem. The problem appears with other distributions that use Xorg 7.0.0, Fedora Core 5 for instance, as well.
