Hi, again -
1. "X Windows" is your GUI - I'm guessing that you probably don't want to disable it.
If you do, the easiest way is to change your default run level. For now, let's not discuss "What's a runlevel?" or "How do I change it?"
2. Back to the problem at hand:
It looks like you're using your X Windows GUI, and that one of your GUI programs went berserk and max'ed out your filesystem with an 18GB log.
There are many ways for this to happen.
EXAMPLE:

3. What you need to do is:
a) be aware of what programs you're using
b) Keep an eye on the .xsession-errors log to make sure it stays a reasonable size
4. If the problem *does* recur, then:
c) See if the .xsession-errors log identifies the culprit
d) Otherwise, run "top". The odds are good that the culprit will be doing the most I/O and/or using the most CPU time.
e) Fix, disable or update the culprit (for example, get a new copy of "mplayer").
X Windows is not the culprit; the enormous log was just a side-effect of the root problem.
'Hope that helps .. PSM
PS:
No, you don't need to reboot the PC for an X Windows error. But you should *always* cold-boot the PC and run "fsck" if you ever have a disk-related crash (as you did when your filesystem became full).
