Knowing Knoppix/Recovering from freezes
It is possible for the X Window System, the K Desktop Environment, or an individual application to "freeze up". This section explains what to do if that happens.
Getting rid of an individual application[edit | edit source]
The most common situation is to have a program that just doesn't seem to want to go away. Even when you click the close button on its window, it still won't disappear. To get rid of it:
- Press Ctrl+Alt+Esc on the keyboard.
- The pointer will change into a skull and crossbones.
- Point anywhere inside the window that you want to get rid of.
- Click the left mouse button.
- The errant program will be killed.
Restarting the X Window System[edit | edit source]
If many programs or your entire graphical environment seems stuck, you can try to restart the X server entirely.
Pressing Ctrl-Alt-Backspace kills X. The display manager should bring it back up again.
An alternate way to restart X in Knoppix is to:
- Press Ctrl+Alt+F2.
- Type this command, then press Enter:
- You will see the message "X Window System shut down". This will also end the K Desktop Environment and all its open applications.
- Then enter:
- The X Window System will be restarted. The KDE desktop will appear again as it did when you first started Knoppix.
