I have a mobile radeon 9600 on my notebook, so a LVDS is always connected and at certain locations I use an additional monitor. I did a checkout of the radeon driver and when running start -- -layout "home" I didn't get the 1680x1050 Display and I wasn't able to switch to 3080x1050 (1680x1050-1400x1050). xrandr showed this: SZ: Pixels Physical Refresh 0 1024 x 768 ( 406mm x 195mm ) -11648 1 800 x 600 ( 406mm x 195mm ) -11659 2 1600 x 600 ( 406mm x 195mm ) -1104 3 640 x 480 ( 406mm x 195mm ) -11659 *4 1600 x 768 ( 406mm x 195mm ) *-11648 Current rotation - normal Current reflection - none Rotations possible - normal Reflections possible - none Thanks Matthias

disabling ddc helps on all setups - so closing
