My linux computer has a very low screen resolution

My linux computer has a very low screen resolution. How do I fix that?

This fix assumes CentOS 6 x64, running a Nvidia Geforce gfx-card and using the elrepo kmod-nvidia gfx-drivers.

  1. Connect your monitor straight to the computer, ie do not use a KVM-switch between them.
  2. Start NVIDIA X Server settings-applet.
  3. Click CRT-0.
  4. Click Aquire EDID.
  5. Save it to the desktop and note the name.
  6. Edit /etc/X11/xorg.conf and in the Screen section add
    Option "CustomEDID" "CRT-0:/root/Desktop/edid.bin"
  7. Save and exit.
  8. Connect your monitor and computer to the KVM-switch.
  9. Reboot computer.
  10. Enjoy the new high resolution.

Thanks to Fredrik Svensson for researching this!
