You need set "Virtual" in xorg.conf for your dual display (with different contents on the 2 screens, i.e. extended desktop). e.g. you can set the value "2048 2048", otherwise the server will pick up the largest mode (1360) in your monitors and makes a square (1360x1360) as Virtual screen size (this is the xserver policy for choosing the maximum screen size when startup). See http://intellinuxgraphics.org/dualhead.html for more detail.

Hi, Gordon We have retried on Jaunty Alpha5 following the comment#1. Still it is. Therefore reopen this bug. Do you have some testing on latest code? Does it work or not??
Comment 3 Gordon Jin 2009-03-09 01:42:45 UTC
Yes, the upstream code is working fine on my side. Is the current symptom same as the previous? e.g. I don't think you'll still see "xrandr: screen cannot be larger than 1360x1360 (desired size 2048x768)" if setting Virtual as 2048. If the symptom is different now, I'd suggest to open a new bug to track, with new xorg.conf and Xorg.0.log.

Still be the same error. The platform is x200 with one VGA monitor.
Comment 5 Gordon Jin 2009-03-10 00:00:23 UTC
Please attach the new xorg.conf, Xorg.0.log, xrandr command with output.

We try it again with another configuration file, it works. Seems it is the configuration issue. Ubuntu will use the default config file. If we use xrandr command, it will bring this problem. We have to get a new config file which works for SUSE and test it with no problem. I will close the bug.
