Bug Description

Binary package hint: virt-manager

Whet I'm running a virtual machine in virt-manager, and the mouse is grabbed, if a window (of another app) pops up, the maouse stays grabbed in virtual-machine, but I can't ungrab it, because keyboard input goes to new window. I have to switch to console, kill the app of new window, ant then I can ungrab mouse.

virt-manager should do ungrab in a case it is not topmost window.

Another good reason why everyone should have focus follow mouse :)

Ungrab in case it's not the topmost window is not the right solution. Lots and lots of folks are using focus-follows-mouse, and in that case, it's just plain wrong.

virt-manager should probably notice if it loses focus (for whatever reason) and release the grab if that happens.

I'm seeing a very similar problem. The mouse pointer within a VM will become stuck. If I move the mouse far enough so that actual OS pointer leaves the VM window, I get the OS pointer but it is effectively useless. It can not click on anything, nor does application focus follow the mouse as it normally does (and is configured to).

I'm not entirely certain of the cause, but have noticed that it consistently happens if the mouse is in a VM console (display through virt-manager's interface) and another application takes focus or the screen saver activates.

Should probably also be noted that this problem has not yet occurred when viewing the VM's display through a normal VNC client (using a KVM provided VNC display, not a VNC server running in the guest OS).

Thanks for reporting this issue.
Do you still have it?
Are you able to reproduce this with a recent version of Ubuntu, such as Karmic or Lucid?

which window manager are you using? How exactly are you trying to ungrab the mouse, using control-alt? What sort of window pops up? Would doing 'sleep 1m; xterm &' in another terminal, then letting the VM window take the mouse suffice?
