Red Hat Bugzilla – Bug 488
Screen keeps refreshing if Xconfigurator is set to wrong monitor freq.
Last modified: 2008-05-01 11:37:48 EDT
I had installed my Linux 5.1 couple of months back and was
working on it smoothly. I also had Xwindows installed and
console login used to comeup automatically on reboot. But
then yesterday I ran Xconfigurator to set some monitor
and mistakenly set the monitor refresh rates to wrong
Now if I reboot, the console login pops up (not the Xwindows
and then the screen keeps on refreshing not allowing me to
start Xwindows or login. Cntrl+Alt+Del works which just
the machine. Because I have lot of stuff already on the
hard drive, I can't reinstall Linux because it would
format the drive.
You need to boot the machine into single user mode but typeing at the
LILO boot: linux single
This will eventually get you to a BASH# prompt where you need to use a
text editor to edit the /etc/inittab file. Change the number 5 to
number 3 in the line
This will allow the system to reboot without trying to run the X
login. Then rerun Xconfigurator to set the monitor to correct
specifications. If you feel everything is again set correctly then you
can change the 3 back to a 5 and reboot the machine.
