[Bug 749817] Re: natty regression: screen goes black when external monitor is connected

 

Dear Martin,

regarding problem 1:
Using the notebook display as my left and the monitor as my right screen, I observe this artifacts, that you describe:
- Context menus leave a rectangle painted with background behind (Gnome).
-  Auto-hiding panels do not reappear when moving the mouse to the border or shortly appear when moving the mouse pointer away from the border (Gnome)
- Was thrown back to the login manager after loading a flash video in Firefox. (don't know, if these two are related.) (Unity)

These artifacts appear rarely and in an unpredictable manner.

regarding problem 2 and 3:
- I can't confirm this. My external display just stays black. Sometimes, only the mouse pointer appears but nothing else

My setup (as a reminder; posted it already):
Thinkpad X201 in Ultrabase connected to external monitor via hdmi-DVI (using the original Lenovo hdmi to DVI converter).
