Unhappy Cannot alter resolution

Hey fellows,

I run FC5 on my old SONY as a server and can't alter its resolution.

The resolution seems to be like 500 by 500 (something like that -- very small) and working at such conditions is really adverse.

I attempted to do the run/edit regular software that came with GNOME to alter the resolution, but it provided only one -- the one i had. However I know it can do up to 1024 by 700--something.

I'm looking forward to edit some type of scipt I guess which would configure it correctly.

I would really appreciate your aid.

XServer and resolution.... that has always been my favorite configuration issue.

Have you tried running system-config-display? There the Hardware tab under which you can choose the monitor you're using. Maybe your monitor isn't recognized correctly?

If that doesn't work for you then what you need to do is to edit /etc/X11/xorg.conf. That, however, is something that's difficult to explain since there is a number of ways to edit it to achieve the same outcome. What I would like to suggest first is to remove any and all Modes sections form xorg.conf. Then add a proper modeline under Monitor section and a corresponding Display subsection under Screen section. You also need to add your monitors parameters under Monitor section. Read man xorg.conf to get the picture. I'll add my xorg.conf here for reference. Note the HorizSync and VertRefresh line under Monitor section. Those you need to find out for your monitor. Probably also DisplaySize.

This is here just to get you started. I'm not responsible for any damages editing xorg.conf might cause to your hardware. Yes, you can fry your monitor by making improper changes to xorg.conf, so please read man xorg.conf carefully.

EDIT: Remember to make a backup of your xorg.conf before editing it!

uh... by 'modules' I hope you meant 'modes'. If you actually removed modules then there has happened something that I can't explain. Anyways, glad you got it working. That was the goal, after all.
