Created attachment 27452 [details] Xorg log, with switching resolution and active compiz. I am using Ubuntu 9.04 with the xorg-edgers PPA and a vanilla mainline Kernel 2.6.30 with active KMS from the Kernel PPA on an Asus EEE 901. According to the intel specs I set the virtual resolution to 2048x1536. I have an 23" LCD monitor with 2048x1152 pixels. I now deactivated the internal LCD with the Ubuntu Display Prefrences and activated the Samsung LCD. It changes the resolution, but Compiz only show a screen with an artefact background with a normal moving mouse cursor. Reverting the display settings back to internal LCD or using smaller resolutions on the external display brings compiz back to live. When I start compiz, it says: mabl@dogmatix:~$ DISPLAY=:0 compiz Checking for Xgl: not present. xset q doesn't reveal the location of the log file. Using fallback /var/log/Xorg.0.log Detected PCI ID for VGA: Checking for texture_from_pixmap: present. Checking for non power of two support: present. Checking for Composite extension: present.

I used tail -f on the syslog and xorg logs, but the log is quiet. mabl@dogmatix:~$ uname -a Linux dogmatix 2.6.30-020630-generic #020630 SMP Wed Jun 10 09:45:40 UTC 2009 i686 GNU/Linux
This should be supported. But I don't have monitor with 2048 resolution (our 24# is 1920x1200) to validate this. How about if disable compiz?

I assume UMS stands for Userspace Mode Setting, right? So I deactivated KMS, set the modedebug option and started the system without an external monitor connected. I then connected the monitor and deactivated the internal LCD. => Same result, mostly black screen with some artefacts and a normal mouse cursor.
Gordon, this doesn't sounds like a modesetting bug. you could either leave it for ma ling to figure out later or give it to jesse or eric for quick fix. you decide.
agree this is not modeset bug. Jesse, could you take a look?
