Debian 5 Display resolution out of range

debiandisplaygraphical-user-interfacexeon

After installing Debian 5 on a Dual-Core Xeon machine, my display connected to the NVIDIA Quadro FX display card shows me an "out of range" error after the boot-up completes. I see the terminal text (login prompt) though.

This is mostly because my card is supplying a video signal of a higher resolution than 1024×768. How do I lower the resolution via the login prompt? I've installed Debian with the grub bootloader.

X11/Xorg are hard to deal with at the best of times.

Now there are a couple things you can do. One would be to familiarize yourself with the Xorg and write a new config by hand. It may not sound like much fun, but you'll be better able to handle such issues in the future.

Another option is to let dpkg re-create the default config for you. You can do this by running:

sudo dpkg-reconfigure xserver-xorg

If that doesn't work out the way you'd hoped and you have the nvidia proprietary drivers installed, you should be able to have them create a more better config that takes full advantage of your video card. The command for that is:

sudo nvidia-xconfig

Now remember, in order to see any changes, you are going to have to restart Xorg. Depending on your distro and version, you can do this by pressing Ctrl-Alt-Backspace, but you'll have a guaranteed restart of Xorg by logging out. If you're level of FUD is high enough, just restart.

Good luck and I hope this helps.
