GUI not working after changing resolution in Centos 5.4 on Dell Optiplex 280
 

After installing a Dell Optilex 280 desktop with Centos 5.4, I configured sendamil, squid and all the extras I needed for a proxy and email server. All was fine until I switched the machine off. I had changed the resolution before and all was working fine. Now I have lost my gui , the system starts O.K but goes blank after "starting udev". I can use webmin to administer the server from a nother desktop/laptop but the monitor is totally blank. I tried most configurations on the /etc/X11/xorg.conf file even tried to create a new one using X -configure but still nothing changed. I cant afford to reinstall because of the time it takes to update the box, our broadband connections are so expensive this end of the world (Zimbabwe) and not so effecient. I have looked at the logs and tried to google but the solutions wont work for me? I suspect there could be an issue with the intel graphics adapter?? Thanks in advance for your help.

Hi,

connect from remote to the machine using ssh and check /var/log/Xorg.0.log for errors or post this logfile here.

boot into SINGLE user mode
and from the terminal tyr this
and reboot as normal

or run the command from the install cd in RESCUE mode

Thanks all for your responses, I had already done the suggested fixes such as moving the old xorg.conf and rebooting, what I can do for now is figure out how I can send the log file. Thanks
