I am using ubuntu and some times it is going to hanged stage while running 2 or more webapps simultaneously. Is there any way similar Alt+Ctrl+Delete to Task manager in Windows for sudden terminations?

If your screen freezes completely you can do crtl + alt + f2 to get a terminal.
From there you can use top which will display running proccesses. Press k and then enter the PID of the process you want to kill.
Or you can use ps aux | grep proccesYouWantToKill to get the PID and then kill -9 PID to terminate the process.
crtl + alt + f1 - f6 are comand line only crtl + alt + f7 will bring you back to your desktop.

  • Then try what I have mentioned above. If you don't get a TTY with crtl + alt + f2 your complete computer crashed and you have to restart manually. – Pabi Jul 02 '14 at 10:09

  • Also kill -9 -1 is useful if wanted to kill all process and this will back to login screen! – Pandya Jul 02 '14 at 11:04
