What To Do When Your Ubuntu System Hangs/Freezes??
[tweetmeme service=”bit.ly” source=”LeisureHoursWP” ]
Most of us must have faced this problem when our ubuntu system hangs and does not respond to any thing / keystroke or command. What to do simply?? Simply press power off or restart and you will be getting weird messages when next time your system boots .
What is the safest way to handle this problem??
You have the press the following key combination to safely restart your system to recover from such situation
Alt + print screen + R + E + I + S + U + B
Important — Order to press the keys
- Keep the alt and “print screen” key pressed during all this.
- Then press the remaining keys in sequence one after the other one at a time. i.e. first press R , then release R, then press E , then release E and likewise.
- It it does not seem to work, try to keep the keys pressed for a little more time and then release.
But another problem?? Who will remember this key combination?? Better I restart manually than this key combination.
Dont worry here is a mnemonic to remember this.
If you want to simply shut down the system safely in case of a hangup, Use the following key combination
Alt + Print Screen + R + S + E + I + U + O
The way to press these keys is similar to previous one.
Now time for mnemonic —
- Out of order
If you are curious what each option is doing , then best resource is official kernel documentation. Here is the link.
Hope it saves you from a problem!!!
