[plug] Lost X autostart

OK, I'm pedantic so:
"X" or "The X Window System" or "XFree86" please. It's not "windows".

A little more info would make this question easier to answer.

The X display manager you've been using is probably not starting for 
some reason.

First try to start it manually - "/etc/rc.d/init.d/gdm start" and see if 
that works. If so its likely you've somehow disabled it from starting at 
boot - use chkconfig to re-enable it ("man chkconfig" or mail for help).

First you could've disabled/uninstalled your display manager (gdm or kdm 
ususually) - do "rpm -qa | grep [gkx]dm" to find out if its installed. 
To check its set to run on startup, "ls /etc/rc5.d/S???dm" and see if it 
prints something like "S99gdm".

If its uninstalled, go and re-install it from your distro CDs.

If gdm/kdm appears to be both installed and set to load on startup, 
check the system logs like /var/log/messages for interesting references 
to X and/or gdm, plus "grep [gkx]dm /var/log/messages | less" and see 
what you get. /var/log/gdm can also contain intestesting stuff sometimes.

Hope this helps.
