Using Redhat 9, installed it with X

All worked well until I had to swap monitors from a 17" LCD to a 17" CRT monitor. Since then when I boot I can hear X loading, but I can't see it. The screen goes blank. I can Ctrl Alt Tab F2 which takes me to a CLI, but no X. On the blank screen where I should be seeing X I can even type in the username and password and hear it accepting it.

I changed the runlevel from 5 to 3 but when it boots is says that the -F Option is disabled and so the runlevel change made no difference.

Help please!!!

You need to reconfigure X and enter new monitor settings...Do you have the monitor manual? If you do, login in console mode, open /etc/X11/XF86Config-4 in any text editor (it you have mc installed it may be the editor from mc). Find 'Section "Monitor"'. You need to modify HorizSync and VertRefresh lines. The values are in your manual - usually at the beginning or at the end of it.

worked like a charm

thanx

I am having the same exact problem also in RH9. My old monitor went up in smoke last night so I had to get a new one! However, I'm not sure the above solution will work for me. If I go to /etc/X11/ , I find XF86Config, but not XF86Config-4 as mentioned above. If I try to run XF86Config, I get a "command not found" error. What is going on?

Thanks in advance!

It's not an executable - it's a text configuration file. You need an editor to modify it - vim, emacs, joe, pico (all text mode and are installed or on your installation cd).
