I noticed several strange issues today with my laptop, a Dell Latitude E6520 running sid. I have not updated this box in the last couple of weeks.
When I went to shut down this morning to leave for work, clicking on the lock/leave icon in the system tray, or from the menu, it did nothing. I had to su ; halt, which worked.
When I got to work, I went to boot, and once the machine was up, I logged into kdm. It went through the startup, and the login screen blanked, but it took an inordinately long time for the desktop to appear...
When the desktop did appear, there was something kind of strange. At work, I have a docking station with a second monitor attached. Normally, the screens are separate, and I have two images, one on each screen. Today, I had a single image stretched across the two screens.
