Ähh, o.k. How can I start X then in 1024x768 clone mode without any virtual
screen. This would be my default setup. Only when I connect to the docking
station with the external monitor, I would like to switch to 1280x1024 clone
mode (with the virtual screen on the laptop LCD) or the dual-head-setup.

Oh, sh... Typo. I will correct that.

O.K. so one needs a combination of xrandr and the CTRL-ALT-Keypad in order to
switch between these three modes?

I thought ALT-SYSRQ-S + ALT-SYSRQ-U should do (sync and remount ro). But that
did not work. Next time I try to issue "sync" and see what happens...

6.5.8.0-1 from Debian unstable.

Xorg.0.log says:

(II) LoadModule: "radeon"

Does that help or do you need other info?
