Public bug reported: This occured with my Dell Latitude D600 in a docking station. Perhaps this also applies to regular Computers. When the monitor isn't connected on boot-up or is switched off the resolution of the desktop is set to 800x600.
** Affects: Ubuntu Importance: Undecided Status: Unconfirmed -- [Edgy] Resolution set to 800x600 if no monitor connected https://launchpad.net/bugs/79057 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
