How to use external monitor as primary screen

[josh6847]

I am running Ubuntu 8.04 on a laptop. I have a 19" Acer monitor and in the past have successfully configured my xorg.conf to handle dual monitor setup with 1024x768 on the laptop and 1600x900 on the Acer monitor. What I have done now is run the laptop through a KVM switch. Due to this, I would like to set the Acer monitor as the primary monitor and just shut the laptop. How can I project my laptop screen to my Acer monitor so that I can use the 1600x900 resolution available rather than just cloning my laptop and using 1024x768? Thanks.

You should be able to use both screens by going to Display Preferences, and setting both to the right resolution, unchecking "mirror screens". Then hold Alt while dragging the top/bottom panels to the bigger screen, then you can just use the laptop as second screen.
