How do I print multiple pages per sheet?

If you want to conserve paper or don't want to carry around a lot of paper, it is possible to print multiple pages on a single sheet of paper.

There are two utilities for setting multiple pages on one piece of paper. They are called mpage and psnup


You can send this output straight to the printer to avoid creating temporary files:

mpage -2 -Pprinter

See the man page for more info (type man mpage).


Sometimes mpage will fail on complex PostScript pages.

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:

2. Log into another machine
3. ssh into the machine that is frozen
4. type

If not, type

Substitute your_username with your username. You can verify that the process is no longer running, by typing:

pgrep -u your_username firefox


pgrep -u your_username mozilla

Then try running Firefox again.
If this still doesn't work, then type:
