Public bug reported:
Binary package hint: gnome-control-center
I am using Ubuntu 8.04 on a Toshiba Portege R500 laptop. I use my laptop
at home and at work, and have an external monitor at work (a BENQ
T241WA). I often suspend my laptop when travelling, rather than shutting
it down.
After disconnecting an external monitor and waking up from suspend, the
panel at the bottom of my desktop is not visible (presumably it is on
the missing external screen). In this case I have to go to
System->Preferences->Screen Resolution to rescan the screens and remove
the external one.
When I run Windows (this is a dual boot system) it is easy to choose
whether to use the external screen in full resolution and just disable
the laptop screen, or to use both (with different resolutions and
different content). Both of these choices are difficult in Ubuntu, where
the default behaviour seems to be to put the same content on both
screens, but if one is screen is smaller, only show what you can from
the top left corner. It doesn't seem to help to drag the screens in the
Monitor Resolution Settings window to different positions relative to
each other. "Clone Screens" is not set.
When waking Ubuntu from suspend, there seems to be some trouble using
the external screen. When I connect it, I get "Out of range" errors on
the screen. This usually works after rebooting, however.
When I have 2 screens connected at different resolutions, I seem to be
experiencing some oddity when opening new windows. Terminal, for
example, opens as a frame with transparent content, except for the line
with the prompt, which is white. Clicking anywhere in the window, using
alt-tab to switch windows, otherwise causing a refresh/redraw, makes the
window turn the expected white. New windows also open a semi-transparent
frame that is larger than the window itself, and that remains semi-
transparent on the desktop. This also disappears when I do something to
cause a refresh.
