Hello,
i am in deep trouble.
i wanted to edit the login screen/gretter of gnome/kde.
i made some changes in the gdm.conf file located in \etc\x11\gdm\.
but, i forgot to make a backup, when i saved changes .and restarted the system, the x server couldn't start.

"FATAL SERVER ERROR:
XF860OPENCONSOLE:cannot open virtual console3(input/output error)"

i don't know whats the problem. i have replaced the origional edited file with the factory-gdm.conf but of no vail.i have to get my box working as soon as possible, i need all the help that experts over here can offer.
Plz help me fast.thanking in anticipation.
Regards.

remove the gdm package, then gdm configuration then reinstall gdm package

but how do i accomplish this, as my system doesn't load , i mean , i cann't start kde nor gnome.
System is halted during the booting process saying that
INIT: xxxxx 3 respawning to fast:disabled for 5 minutes
INIT: xxxxx 4 respawning to fast:disabled for 5 minutes
INIT: xxxxx 5 respawning to fast:disabled for 5 minutes
INIT: xxxxx 6 respawning to fast:disabled for 5 minutes
Now , how do i get out of this state and remove the gdm package and then reinstall it?

while booting, give the option linux 3 to the kernel boot line.
Now it will boot into runlevel 3. the multiuser, command line interface.

login as root
remove packages using rpm -e gdm
or give siutable command if not using rpm based distros.

then remove any configuration files in /etc/x11/gdm/ (remember its forward slash "/" in Linux not "\")

the reinstall the rpm .

But if u need gui, then after u login as root, type startx.
