[SOLVED] Monitor blanks out when accessing Display Properties in KDE


Hello Gentoo forum,

I am running Gentoo and KDE 4.3.1 and using the latest Nvidia display driver which was downloaded directly from Nvidia's web site.

Everything boots up fine and KDE starts with no problem with the proper display resolution.

But everytime I click on System Settings - Display Settings - Size and Orientation, my monitor blanks and the monitor gives a message saying the monitor is out of range. I can not kill X so I am forced to give the computer a cold reboot. I can access the Nvidia control panel with no problem. If I enter KDE as a root user, the problem goes away.

Below is a copy of my xorg.conf:

Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig

Hello again Gentoo forum,

I am happy to announce I solved my problem by editing one of the hidden files called .kde4 then I navigated to the the share folder, then the config folder, then the krandrc file. That file had my monitor resolution too low and the refresh rate too high.

I got the correct information by copying the krandrc file while I was booted up in KDE as root since I did not have the problem in root.

I also think the reason the information was wrong was because when I first installed KDE I used a generic vesa driver and the information in the krandrc file was probably from that vesa driver. So when I installed the Nvidia driver, the information remained the same in the krandrc file, causing the problem.
