Public bug reported: The symptoms : I do "something" (haven't quite put my finger on it yet) that causes the left mouse button to appear stuck down (its like a MOUSE_DOWN event happened, but never a corresponding MOUSE_UP event).
The stuck mouse button manifest itselfin Intellij IDEA, which basically becomes unusable. Many times when this happens, the same behavior is also present on applications inside the virtual box VMs. I generally have the following three programs running at all times, so I think it is triggered by something in them (I have a sneaking suspicious its using the mousewheel to scroll up / scroll down in the virtualbox vm). - Intellij IDEA - Virtual Box (usually running a few windows VMs) - Chromium To solve the problem, I end up having to completely reboot (which kills a lot of time, because I have to alsy cycle the VMs). As far as what triggers this problem - it is somewhat hard to determine but I think it may have something to do with using the mousewheel while the focus is on one of the virtual box VMs. One other thing I've noticed is that the problem only seems to happen in Unity. If I choose Gnome shell then I've not had the issue (but I end up coming back to Unity since its grown on me). Other people have also reported the same or similar issue here (I also posted a description there) : http://askubuntu.com/questions/155499/regain-control-of-mouse-by- restarting-xorg/179571#179571 I am using 12.04 64-bit. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040844 Title: Left Mouse Button Sometimes Gets Stuck in Unity (12.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1040844/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
