I'm running Ubuntu 12.10 with Unity 6.6.0, and I have faced this problem as well. I can confirm that I was too running a virtual machine, when this happened. Specifically, I was running a Ubuntu 12.04 VirtualBox image (set to not exclusively capture keyboard and mouse). One behavior I noticed was that tapping the Super or Alt key would open up both the host's and guest's Dash or HUD, respectively. This is somewhat expected, I guess, but sometimes annoying.
I did not notice exactly when the host's HUD became permanently visible, but it has stayed there even after I closed the VM. Attached screenshot shows that the HUD is as if painted on the screen, but not really alive, i.e. I cannot type anything into or close it by tapping Alt (strangely, the cursor even blinks sometimes). Elements from other windows (in this case a terminal) get drawn on top of the HUD, and then sometimes the HUD gets drawn on top (typically when the other window loses focus). I haven't experienced any such problem with the Dash. ** Attachment added: "Screenshot showing HUD refusing to disappear" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1036873/+attachment/3362390/+files/screenshot_HUD-stuck_2012-10-01_14-03-02.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1036873 Title: HUD/Dash refuses to close To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1036873/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
