(kubuntu 8.04) When I open an OpenGL game my TFT/LCD monitor displays an "out of range" masage (i thnk it supports up to 60Hz) I searched and found that i would have to edit my Xorg.conf file but whenever i did it the X-server crashed and i had to reboot from recovery mode to reset it. My graphics card is geforceFX 5200 and i installed the drivers with envyNG(I can't post the site since this is my first thread).
Does anyone know how to solve this problem?

May be you have the wrong driver ??
Files in my Ubuntu 8.04 for FX5200 :

903. linux-restricted-modules-2.6.24-16-generic 2.6.24.12-16.34
904. linux-restricted-modules-common 2.6.24.12-16.34
905. linux-restricted-modules-generic 2.6.24.16.18

970. nvidia-glx-new 169.12+2.6.24.12-17.36
971. nvidia-kernel-common 20051028+1ubuntu8
972. nvidia-settings 1.0+20080304-0ubuntu1

(The numbering is from 'pdbv' PackageDataBaseView, list.html)

Most flatpanels are 60 Hz, recommended for xorg.conf is 60-60,
or use 'sudo nvidia-settings' "set 60" and "Save X Configuration"

( I have 2 old "difficult" Compaq panels )

Rgds
P.S.: Just tested 'gl-117' runs fine, quality 5, view 130.

There is some progress! With sudo nvidia-settings i set the refresh rate at 800x600 end i press "save to X configuration file" then i run the game and it plays! but the problem comes back when i change the resolution to 1240x1025 the game gets "out of range" again. I noticed that the "double scan" option at 60Hz displays the "out of range" massage again i thing that the game is trying to use this "double scan" option and that is the problem. Do you know any way to get rid of it?

I Solved IT! The broblem was with double scan but when i edited my xorg.conf i typed the modes separated with "800x600 +0+0" "1024x768_60" but i should separate them with ";"
e.g. "800x600 +0+0; 1024x768_60"

Thank you for your help you gave me the push i needed by showing me the "sudo nvidia-settings" command that allawed me to change th xorg.conf file
