RHEL xhost unable to open display ""

We rebooted the server an got the following error:

Quote:

Can't login or do anything at the monitor or kb.
How ever I can ssh to the server, not sure where to start looking.

I have two servers that are the same and checked the xorg.conf on both servers and they looked the same.

Thanks in advance,

Hi,

Most likely X is not running.
Check /var/log/Xorg.0.log to see if you find the reason

Check out the DISPLAY environmental variable in profile or resouce configuration file of the user whom you are trying to login

#echo $DISPLAY

If there is an IP pointing to some other machine then system while login will try to export the X server to that pointing machine and eventyually fails.

Remove the entries in profile or resouce configuration file via ssh login and try login to the machine via VGA console.
