I don't remember if it was tied to a specific popular Linux distribution,
but this used to be the common response to new Linux-converts when they
asked for the Linux version of Ctrl+Alt+Delete (to kill a hanging process).
I remember some modifier keys and escape, but I can't confirm that it was exactly "Ctrl+Alt+Esc". The key combination would launch "xkill", which now shows a skull-and-crossbones cursor instead of an "X" (on my machine, at least). Using the skull-and-crossbones to click on a window will kill the process corresponding to that window.

At time to time my XFCE4 freezes. The screen is responding to the
keyboard, mouse pointer is moving on the screen but nothing is responding.
I just lookup some solutions and found this one:
- press: CTRL+Alt+T (to get to terminal)
- pidof xfce4-panel
- kill -9 pid
xfwm4 --replace &
Any other solutions?
I ask ChatGPT for a solution to this and I got:
1.) Try using the keyboard shortcut Ctrl+Alt+Esc. This will turn your
mouse cursor into an X symbol, allowing you to click on the window that's causing the freeze and kill it.
2.) If the keyboard shortcut doesn't work, try switching to a virtual terminal by pressing Ctrl+Alt+F2. Log in with your username and password.
3.) Once you're logged in, use the top or htop command to identify the process that's causing the freeze. You can sort the list of processes by
CPU usage or memory usage to make it easier to find the offending process.
4.) Use the kill command followed by the process ID (PID) to terminate the process. For example, if the PID is 1234, you would use the command kill 1234.
5.) Switch back to your X session by pressing Ctrl+Alt+F7. Your XFCE4
desktop environment should now have restarted, and you can log in as usual.
"Ctrl+Alt+Esc" doesn't work, and I've never seen this solution; where
does it come from?
