Whenever I log out of KDE or Gnome and I'm trying start X again, I get this error when I type in "startx":

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock and start again

So I used to use "startkde" and it would spit out a couple of errors, but then it would start. But it doesn't start anymore, I just get this error:

rm: cannot remove `.' or `..'
rm: cannot remove `.' or `..'
xsetroot: unable to open display ''
xrdb: Can't open display ''
xset: unable to open display ""
startkde: Starting up...
ksplash: cannot connect to X server
kdeinit: Aborting. $DISPLAY is not set.
Warning: connect() failed: : No such file or directory
ksmserver: cannot connect to X server
startkde: Shutting down...
Warning: connect() failed: : No such file or directory
Error: Can't contact kdeinit!
startkde: Running shutdown scripts...
startkde: Done.

Can you tell me what's wrong? I'm using RH9, if that helps.

I don't really understand what you mean, logging out of KDE. You should see then a menu which lets you shut down, restart or login again.

If, by whatever means you are really at the command line, try Good luck .
