Configure second monitor to sit to the right of laptop

You'll need to make sure your xorg.conf permits a virtual screen size this big. If it doesn't then xrandr should return a suitable error message that tells you the required size.

Know a better way?

If you can do better, submit your command here.

What others think

Actually, at one point I used this very simple command on my Eeepc to write a bash daemon to monitor the VGA connector, and automatically set up this sort of thing. This accomplishment was both my first real shell script, as well as my first contribution to open source (i was so proud when someone found it useful enough to make it work better ^.^)

The thread regarding this script is here:


with a couple tweaks added by KnightRider to make it work a bit better later on (the best version is the in the last post).

No promises that it will work for you (it requires a bit of configuring anyway), but I found it very handy when I used my laptop as a primary machine.
