“It’s Not Listening!”

The computer is on, you are working away, and suddenly it doesn’t respond to anything you type. It’s the Abominable Frozen Computer.

The computer is probably fine — it’s a program that has frozen up. Try these things to try to get the program’s attention:



Press Esc a bunch of times.



Press Ctrl+C a bunch of times.



Press Ctrl+D a bunch of times.



Press Ctrl+S and then Ctrl+Q a bunch of times. (You never know what works.)

If you are running KDE, GNOME, or another X Windows-based system, see whether you can use the mouse to select another window or whether you can type a command or two in a shell window. If you can, you can probably arrange to murder the frozen program and start it up again (see the following section).



If your window system is completely stuck, you can usually murder the window system and start it over again without having to restart your computer (refer to Chapter 4).


If your computer is on a network or has more than one terminal, you can ask a computer guru to kill the program. If you’re feeling brave, you can kill the program yourself. When you kill a program, you lose any work you were doing in that program since the last time you saved data to the hard drive.

Tell the wizard what happened (in order), which programs were running, and what you did. She will probably kill the process, as described in Chapter 23. If you have a number of processes running, she may kill one after another until your computer feels better.
