View Full Version : [ubuntu] 10.10 upgrade GDM multiple display issue

October 21st, 2010, 12:31 AM
I've a display issue after upgrading to 10.10 . I have a Dell Inspiron notebook with an ATI 1200 chip set. Prior to the 10.10 upgrade I could connect a higher resolution monitor to the VGA port and hit Function F8 to switch my display from the notebook display to the external display to take advantage of the higher resolution of the external display. With the 10.10 upgrade when I switch to the external display I have no window management functions, ie I can't resize or move windows because there is nothing to grab onto. If I click the show desktop icon I get a message to the effect that the function isn't available for GDM "unknown"

If I used mirrored displays with the external and internal displays at the same resolution then I do have window management functions.

Any ideas?

I completely removed Compiz and my external display works as expected
