Hidden Linux : Divide and Conky
Conky is, in it's own words, "a free, light-weight system monitor ... that displays any information on your desktop." Sounds pretty dull, right? Well check it out ...

Installing Conky's a doddle: just use your package manager. For Ubuntu/Debian users, that means simply typing
| sudo
apt-get install conky |
on the command line.
Once it's installed, you'll need a .conkyrc script in your /home/username folder. Here's a basic one to get you started ...

Now all you need do is kick off Conky by hitting Alt+F2 and entering conky, or type this on the command line:
| conky
& |
(The ampersand (&) will make it run as a background process.)
Now here's the fun part. Open .conkyrc in a regular text editor and make changes to it. Save those changes, and your display should be updated. Make some more changes, save them, and again you'll see the changes immediately reflected in Conky -- well, within a second anyway. That's what that line;
update_interval 1
is all about. In practice, once you're happy with your setup, you might want to reduce it to only update every five or ten seconds.
And what if the Conky display disappears altogether? Use Undo to undo whatever you last changed in .conkyrc and re-save it or, if it's totally screwed, use Alt+F2 or the command line to enter killall conky and restart from scratch.
For (much) more documentation on settings and features, type
| man
conky |
or
| man
conky > conky.txt |
to copy the manual pages to a file called conky.txt, from whence you can study them at leisure!
