Exclamation How to change screen resolution

Hi. I just installed Debian Lenny on my laptop. I really like it, but i don't know how to change the screen resolution. I tried using the program for that, but it only has on resolution, so i dunno. Does anyone know what i should do???

In case it helps this is my Xorg.conf file:

Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "kbd"
        Option          "XkbRules"      "xorg"
        Option          "XkbModel"      "pc104"
        Option          "XkbLayout"     "us"

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"

Section "Device"
        Identifier      "Configured Video Device"

Section "Monitor"
        Identifier      "Configured Monitor"

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
hope this helps

did you try dkpg-reconfigure xserver-xorg ?
in the dialog based config you can specify the resolution you want.

some quick info first.. what graphics chip do you have ? lspci
Just in case you need adifferent driver for it..

also the output of the following command so we can see what driver it's currently using
cat /var/log/Xorg.0.log | grep autoconfigured

If your drivers and whatnot are correct, then I would suggest using a Modeline

This advice really no longer applies. With the newer xorg (ie, as of Lenny), you get no choices about screen resolution, and you are left with a very minimal xorg.conf (as the OP has). Theoretically, everything should be autoconfigured for you, but it doesn't always work out that way. As Farslayer suggests, the OP may need to install a driver (say for Nvidia or ATI) or mess with xorg.conf and modelines.
