Re: Linux is bad at controlling bad behavoring programs
There are two things you can do. First thing: Have a Launcher item that runs the "xkill" program. When you click on the Xkill icon, the next mouseclick will kill whatever program has its window underneath the mouse cursor (i.e. click Xkill, then click Firefox, and Firefox will be killed).
Alternatively, you can hit Control-Alt-F1, log into the text terminal, and run 'kill' or 'top' from there.
It's not that "Linux is bad at controlling bad-behaving programs", it's just that "Linux handles it differently". You're obviously quite new not to realise that Linux does almost EVERYTHING differently to Windows - and that doesn't make it better OR worse.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
