problem...

When I boot, all I get is a little window in the upper right:

ClientList	SessionLog
Checkpoint	Shutdown


and a window in the bottom right:
Console log for rat.thirdeyemediaworks.com

I can't do anything with my mouse, which is just dancing all around the screen.
I can't open a terminal window. If I telnet in with another machine, I can
startkde, but my mouse is so crazy, I can't click anything.

I can do stuff su-ing as root from another machine, although all the paths are
messed up. For instance, I edit my firewall script and try to restart it via
telnetting, but the script cannot find ifconfig! It can't get my eth0 ip.

I wouldn't mind doing everything from a terminal from within my net, but how do
I fix my paths without screwing stuff up? When I tried to restart my firewall,
everyone lost internet access because of this paths thing.

Any help is much appreciated...
