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). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/749817 Title: natty regression: screen goes black when external monitor is connected -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
