redhat CUPS >> monitor resolution error ??

hi , i sucessfully installed linux redhat 9.0, but my monitor wos not a monitor on the list ,by default it was on unmounted monitor, but i changd it to a compaq,

when i try to go into linux redhat 9.0 using lilo, it comes up with a kernel panic error,

however if i use interactive mode using the I key and i read another post that if u say NO to the CUPS then it will boot in normally,

i tried that and it didnt giv me any kernel panics, however, at the end of everythin loading up, i sed YES to Firstboot and then the monitor kind of switchd off,

i then tried CUPS to NO and Firstboot to NO and this time i got a glance of a text based login

it sed


and then the monitor switchd off,

due to past experiences with similar situations, i typed in (whilst the monitor was automatically off)

my username then i hit enter then i typed in my password, as soon as i hit password the hard disk starting makin noises as if it wus loggin in, btu i could not see anythin on screen,

my question is, how can i fix this monitor thing ? wot command in linux rescue can i use to make the monitor unmounted ? because i think this is the problem ?

does anyone else hav any ideas to wot the problem might be ?

CUPS is a printer service. It doesn't do anything even remotely related to monitors. I think you have two unrelated problems.

Try running "linux single" from your LILO prompt. If that gets you in, edit / /etc/inittab and make sure initdefault is set to 3. (If it's set to 5, it will try to switch you to X.)

I think your mistake was telling it the monitor was something it wasn't. Run redhat-config-xfree86, and this time tell it to use one of the generic definitions. Start with something you're absolutely sure your monitor can handle.

Once you can get in, you can run ntsysv to turn off CUPS, so that you don't have do the interactive boot every time.

After you've run redhat-config-xfree86 you can test X by saying "startx".

I generally always boot into runlevel 3 (text mode), and then I either use "startx" (if I'm just going to want X for a little bit) or "init 5;exit" if I want to switch to X for the life of this boot. The extra little bit of time is not that big a deal (I don't boot my system but once every few months), and it gives me much better odds that I can get into the system to fix whatever might be broken, if anything does go wrong.

Hope this helps,
