    Default KDE4.0 runs ksnapshot endlessly

    KDE4.0 (SuSE 11.0) has decided to start one ksnapshot after another.
    Meanwhile 70 ksnapshots are running and the machine is blocked. I did not
    tell KDE to do so.

    What's this?

    Is it possible you have a stuck key? Press the "Print Screen" key (upper
    right of keyboard, one of those three keys you've never -ever- pushed)

    Ksnapshot is a pretty good system killer... My kitten (The brat!) likes to
    stand on that button... and with 30keys/sec repeat rate... I found out that
    my system can handle over 250 instances! Love him, but he's a brat!

    Thank you. No it's not a stuck key. Meanwhile I think, I located the source
    of problem. I have a terminal window running bash. As soon as I hit the
    cursor up key (repeat last command), ksnapshot starts. If I am not fast
    enough to hit 'close' one ksnapshot is startet after the other.

    Ummm, that's really odd!

    So none of this starts until / unless you press the up-arrow key in the bash
    terminal?

    Is this consistant? Does this happen with ANY bash terminal you open? Can
    you reproduce it at will (not that we WANT to...)

    Yes, I can reproduce it - as long as openSuse11 runs in native mode. If I
    start it under XEN, this effect does not occur!
    I open a terminal and press 'cursor up'. At the same moment, I see the
    startup icon of ksnapshot. According to my latest tests, this happens with
    every cursor key, also with page up, page down, pos1, end, insert and
    delete.
    It doen not happen, if NumLock is off!
    What is strange, too: All three LEDs (Num, Shift, Scroll) are on, when the
    system comes up. IF I hit NumLock, Shift and Scroll LEDs go off, but Num
    stays on.

    Ummmm, have you considered an Exorcism?

    That's really odd behavior! Works fine in xen, wonky in native.

    Well, maybe start narrowing the culprits... is it possible to unplug and
    replug your keyboard once you're in native mode? Maybe the keyboard or driver
    is being set up in an odd manner when not in xen mode?

    Yup, I'm pulling at straws here. If anything, I'd have expected it to be the
    other way around, xen being the bad guy.

    I'm sorry, nothing else comes to mind.

    I've actually run into this before.

    Up in a terminal would register as PrintScreen.

    Hold down Ctrl-Alt-Backspace or restart the computer to kill the Ksnapshot madness.

    Now go back into KDE, and go into the Region settings, and change your keyboard layout.

    Thank you for all the hints.

    I think, KDE gets confused because it's a notebook with keyboard and mouse
    attached by USB. If I start it without external keyb/mouse, it works like
    intended. But the NumLock LED is off, while NumLock is active, and the
    mouse buttons are swapped.
    Started with keyb/mouse attached, I get inverted LEDs, NumLock off and the
    effects descibed.
    Maybe someone writing the drivers could have an explanation.
