Xwindows kicks back to login when left alone
 

Hey all,
If I leave the system for a while, then come back later its at Xwindows login again. Can something be done to stop that from happening?

It depends on what the problem is really. I would check the last few lines of the Xfree log to see whats causing it to crash.

# tail -15 /var/log/XFree86.0.log

See if that gives you any usefull information.
