(Get the code!)
Ubuntu (x64 version).Gnome based desktop(pretty default Ubuntu).
Bug is awfully simple.When some GUI app has hanged there is no simple and evident way to kill it.
Ctrl-Alt-Del offers a bunch of shutdown and system options.
At very best user will find task manager in quite unevident place: System -> Administration -> System Monitor
Also I was not able to find in timely manner if there is any keyboard shortcut to run task manager and\or if it can be changed.In KDE and Kubuntu at least Ctrl-Alt-Del or any other hotkey can be assigned to starting task manager (ksysguard).However not so simple, too.
Expected behavior:
There should be easy, evident and quite stable (in sense of application failures) way to run task managers in both Ubuntu and Kubuntu.
Task manager and method of it's starting should not hope other apps are behave fair, etc.So method of starting shoule be reliable and easy, window should be unconditionally on top of all others.
Kubuntu can acheive all this due to great KDE flexibility with some manual configuration (though you have to configure keyboard shortcut to run ksysguard and "above others" enforcement yourself but KDE at least allows all this).
In Ubuntu I found no convenient and evident way to kill hanged task.Actually when using task manager I will not expect that hanged or misbehaving app will be fair allow me to enter system menu, walk it and start task manager and that app for example not tries to be "above others" itself.
In short, there should be some simple and "die-hard" method to run task manager and it should try to obtain boosted priority and draw winbdows above others to survive even if some app misbehaves in unfair manner.
