I've been using Unity again for a bit with the standard ubuntu kernel, and the unity app bar thing is drawing off-screen here as well (so it wasn't just related to the main-line kernel). Screenshot attached, and running kernel:
$ uname -a Linux creswick 2.6.38-10-generic #46-Ubuntu SMP Tue Jun 28 15:07:17 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux For posterity: The attached screenshot was made after docking and running this alias: $ alias dock alias dock='xset r rate 200 ; xrandr --output HDMI1 --mode 1920x1080 --rotate right --pos 1280x0 --output LVDS1 --pos 0x300 ' LVDS1 is the internal laptop display, running at 1280x800. FWIW, if you count the pixels in the screenshot, the bottom ~20px or so of the laptop display is black, and that portion of the screen won't display windows. It Will display the mouse cursor though. I think this "black bar at the bottom of LVDS1" behavior is consistent with the mainline kernel, but I'm not certain about that detail. ** Attachment added: "screenshot after docking & adjusting screens manually via xrandr. Note the vertical location of the unity app bar thing on the left." https://bugs.launchpad.net/ubuntu/+source/unity/+bug/814721/+attachment/2248112/+files/unity-app-bar-wrong-place.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/814721 Title: [Intel i915] Docking with external monitor often corrupts screen To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/814721/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
