frozen

What do I do if my screen is frozen?

On a Linux machine:

1. Make note of the name of the machine you are on.
2. Log into another machine
3. ssh into the machine that is frozen
4. type

pkill -9 -u your_username

5. This should log you out and kill all the processes.
The frozen terminal should return to a login screen.

If all else fails,

If it is a Windows machine:

1. Hit CTRL-ALT-DEL
Choose Shutdown, then choose Restart.

What do I do if my screen freezes up when viewing a pdf from mozilla?

It seems to be a bug with Mozilla that is causing screens to freeze.
To unfreeze your screen:
1. Make note of the name of the machine you are on.
2. Log into another machine
3. ssh into the machine that is frozen
4. type

pkill -9 -u your_username mozilla

br> 5. This should kill the mozilla process that is running and your screen should return to normal.
If not, type
