Clone a screen with monitor using different resolution


Hello everybody!

I've read through many posts on different forums, but - unfortunately - no post fitted my problem. So please excuse the yet-another-display-question

my laptop is capable to display 1024*786, while my display at home is able to display 1280*1024. I want to use these two resolutions. But I want to clone the display, so that i am able to turn off the laptop lcd.

The laptop uses a i915GM graphics adapter.

Code:
Section "Device"
        Identifier       "Videocard0"
        Driver           "i810"

        Option          "MonitorLayout" "CRT,LFP"

Why did you set DevicePresence as false?. I have three different layouts, I only switched it to true in the one that doesn't work :-p (it's supposed to make the dual-head mode work, but it doesn't anyway...)


Code:
Section "ServerLayout"
        Identifier      "Default Layout"
        Screen 0 "Screen0" 0 0
        Screen 1 "Screen1" 0 0
        InputDevice     "Generic Keyboard"
        InputDevice     "Configured Mouse"
        InputDevice     "Synaptics Touchpad"
EndSection
Did you try?:

Code:
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" clone "Screen0"
