I noticed that MEPIS 7 offers suspend-to-disk capability, so I tried it. It didn't work, saying "The resume partition is not set up. Probably you need to add a 'resume=...' option to your kernel command line and reboot. Suspend to disk and resume is not possible without a resume partition, please consult the documentation. You can skip this check by setting SUSPEND2DISK_SKIP_RESUME_CHECK to 'yes' in the sleep configuration file." Where would I find this documentation?--somewhere on my HD, or on the Internet? (By the way, it would have been more useful if MEPIS had mentioned at the time of installation that I need to create a special partition.)

You don't need a special partition, you only need to make sure that your swap is at least as big as your physical RAM (because swap is where your stuff gets suspended to - unless you suspend to RAM).
Yes, the documentation should be on the internet. You should also be able to get some information from your system by using apropos suspend.

Okay; I was just going by what the message said. What is Apropos Suspend?

apropos suspend is the command you would use to get a list of all software packages that have anything to do with suspending. If you don't like the French sound of apropos, you can use man -k instead. Just try it out, apropos or man -k will give you information about about anything you could do with a Linux box (you can start with apropos apropos).

Ironically, I can pronounce apropos just fine, I simply can't type it very fast. So I have always used man -k instead. However, man -k is the equivalent of only the "plain vanilla" apropos; & does not have the "-w" option available if you need it. Try the following to see what I am talking about: RTM apropos, man

Interesting! But I don' really use either, I use an RTFM bash script to call apropos

What does your script do?
