Resolution Problem


hi

me installed RedHat 9 on a monitor supporting Resolution greater 800*600,
it successfully installed.
but when i changed the monitor which is not able to support resolution greater than 800*600. Linux starts its services and when it is going to load its graphical interface , monitors shows nothing. in backgroud it is working properly but does not show anything.

is there any way that without reinstalling , i change the resolution to 800*600 ?

thanks

Safwan

If you have your desktop set up to go into the command line before starting X (init 3 in the /etc/inittab) then all you have to do is reconfigure your /etc/X11/xorg.conf file by running 'xorgsetup' (assuming you are not using XFree86 which is old). If you have it set to go strait into X at boot, (init 4) then you will need to insert the rescue disk you created at install and boot into terminal mode. Then reconfigure xorg appropriately. If you don't have a rescue disk, a lot of the time distros will allow you to boot your system from the install CD.

I like to keep my computer at init 3 and then go into X with 'startx' so I'm not SOL if X craps out on me. Let me know if you need further assistance.

It depends on your distro. Try booting from the CD and see what it says. You will need to follow the directions that they give you. For slackware you would do this:
Code:
boot: bare.i root=/dev/hda1 noinitrd rw
If it does nto give you proper directions, try getting to a comand prompt from the install CD boot. then: mount /dev/hda1 -t <filesystemtype> / then use vi to change the runleel in /etc/initab to init 3. Once in init 3 you wll be able to fix X apropriatly.

If X fails to load, you can fix it and try again without having to use a rescue disk.
