Hi, I have an external monitor which is an 20" 1280*1024. In windows 7 it works fine with that resolution but in ubuntu it can't.

Example: In windows I connect it and activates it, done. In ubuntu I connect and the only resolution that is available is the ones my laptop screen support, 12" 1366*768.

My laptop is an asus 1201n. If I force it to use 1280*1024 both screen crashes and i have to force a reboot. what should I do?

This is the program to change resolution and other stuff.

    alvar@alvars-laptop:~$ disper -l
display DFP-0: HSD121PHW1
 resolutions: 320x175, 320x200, 360x200, 320x240, 400x300, 416x312, 512x384, 640x350, 576x432, 640x400, 680x384, 720x400, 640x480, 720x450, 640x512, 700x525, 800x512, 840x525, 800x600, 960x540, 832x624, 1024x768, 1366x768
