I have several questions along these lines:
Is there a Task Manager in Linux?
How do you see the pidīs?
I had a program hang and I wanted to Kill it but I could not identify it and then kill it. I have tried to find a thread on this subject and also looked in the man pages.
I tried xkill but I receive a message:
Select the window whose client you wish to kill with button 1....
What window and where is button 1? Is this one of the desktopīs and is button 1 the 1 key? (That had to be the stupidest thing I have ever asked!)
