Compiz does not reset desktop resolution
Bug Description
Binary package hint: compiz
When I attach a external display with a resolution larger than the resolution of my laptop and enable the screen in the screen resolution interface the desktop size does not change. What happens is that the contents of the screen of the laptop are shown on the main monitor, but the rest stays black. The mouse can move on the black, but the windows can not.
switching desktop effects on and off fixes the problem. As can be expected the bug does not occur when desktop effects are disabled.
This happens in a fully up to date Ubuntu 8.10 on a eee 901 which has a intel 945GME graphics card, but I suspect that it is not hardware related.
PS.
Maybe this old bug is related. It is not the same since I do not get a total black screen.

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add your ~/.xsession-errors, /var/log/Xorg.0.log and the output of lspci -vvnn to your bug report as separate attachments? Thanks in advance.
Added the requested attachments.
I also see this rather often when I use xrandr with compiz. The desktop cube rotates in the top-left area the size of my laptop screen, while the rest is not necessarily black -- often it contains a desktop image from when I last used dual-head, i.e. whatever happens to be in the video memory.
I also think bug 206998 might be a duplicate of this one.
The xsession-errors.
