It certainly looks like you are on the right track. Do you have an entry for a swap partition in your /etc/fstab? It should look something like this /dev/hda6 swap swap defaults 0 0
You can use diskdrake to create a swap partition without having to reinstall BTW: Unless you like getting disc corruptions avoid switching off the machine. Use Ctl+Alt+F2 to get a console then as root shutdown -h now If you get really stuck use SysReq keys to shut down. See page 146 of the Reference Manual for details. file:/usr/share/doc/mandrake/en/ref.html/ts-system-freeze.html derek On Thursday 28 February 2002 12:25, you wrote: > Hello, > > I've been having problems with my LM8.1 install, I *think* I've figured out > what's gone wrong, but I'd like a second opinion. > > The problem: I can't use my PC for more than an hour or so.
