Public bug reported: Binary package hint: gnome-control-center
System: HP NC6000 + dock + external Dell CRT Ubuntu 9.10 (though problem was noticed on 8.10 and 9.04) System is normally run with laptop in dock, and external CRT connected, with the display setup as the CRT running @ 1600x1200 on top of the laptop screen @ 1024x768, left hand edges aligned. The system generally misbehaves if the latop is undocked and redocked. Undock works as expected, the windows from the CRT display are resized and moved to the laptop display. However a range of problems can occur on redock; The most common is that the CRT just isn't recognised anymore, and I have to reopen the display prefs and re enable the 2nd display (and resize and reposition it). The system behaves as if I'd never connected the monitor before, it didn't just miss the interrupt of having the display attached, but it had reset the settings for some reason. The 'theme' and general appearance of ubuntu can also change - it will switch from 'human' to 'clearlooks'. I've also noticed that this can happen when the system is low on memory. This makes me think that an exception or error somewhere can cause a 'fallback' to the first theme? The most bizarre I've so far seen is that the offsets for the second display became corrupted somehow, and it would only let me position windows in the right hand half of the screen, and maximising windows put them in a thin (~200px wide) slice down the right hand edge. This problem even persisted across reboots, and was only fixed once I'd moved the relative position of the 2nd display a few times. The width of the no-go area on the left was suspiciously close to being 576 (1600-1024) px wide. Perhaps the window manager and the display driver had different values for the screen offsets? I'll be happy to provide any other information.
