frozen

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

What do I do if my screen is frozen?

If it is a Sun Ray or 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 not,
1. Hit the keys CTRL-ALT-Backspace-Backspace
2. Hit the keys CTRL-ATL-Moon (The moon, is at the top right hand corner of the Sun keyboard.)
The screen should turn off and then should return to a login screen.
