Ctrl+Alt+Del for Ubutnu System.

When Windows hangs itself we all know what to do right? Were just reaching for the combination [Ctrl]+[Alt]+[Del] (Control Alt Delete). But if you try this in Ubuntu Linux nothing happens (In Ubuntu, you actually get the menu for shutting down your system, but this don’t work when your system hags or freezes).

So what to do?

Follow the following steps to restart the session using the follwing key combinations.

[Alt]+[PrtSc]+[K]

Steps: 

• First get into the terminal.

• Change to sudo user using the command.

sudo -s

• Enter your root password.

• Use your favourite text editor and edit the file /etc/sysctl.d/10-magic-sysrq.conf like this.

gedit /etc/sysctl.d/10-magic-sysrq.conf

• You will now see this line of code in the end of the file:


kernel.sysrq = 176


• Change this into:


kernel.sysrq = 180


• Now reboot the system. It will work!!!
