if qemu dies, my mouse dies with it
 

How can I make my mouse come back to life if qemu died (while having the mouse grabbed) and killed my mouse along with it? Is there a command I can send to a proc file or something so that I don't have to restart my KDE session all along? :scratch:

How do you mean that qemu "died"? Did it freeze up with the mouse grabbed? If so, try typing ctrl+alt. This will release the grab if what qemu is emulating crashed, but qemu itself has not. If that doesn't work, you can ctrl+alt+F1 to get to a terminal. There you will probably have to log in. Then type 'killall -9 qemu'. That should forcibly kill any process named qemu. If however, you mean that qemu terminated, but somehow never returned the mouse, then I don't know what to do but restart X.

The second case of the ones you named is the one I'm talking about. Normally a "segmentation fault" is what I see. :wink:

I just noticed there's just a little workaround: start qemu again, grab and de-grab the mouse. It will bring your mouse back to life.
