external monitor on eeepc 900

[Betelgeuse]

How can I use the external monitor on asus eee pc 900?
Ehen I connect my 19" monitor and power on the machine, it boots but a terrible 800x600 resolution on both lcd and monitör. And the xorg.conf was broken. After I disconnect the monitor, power off the machine and turn on again, still the lcd was 800x600 and I could not solve. I had backup of xorg.conf file so I've copied the backup from the console to fix this.

I want to use my CRT monitor when I'm at home and I want to be able to use projectors when I'm out.

This is a topic addressed many times at this forum.. I don't know if there is a stable solution for this? Use propreitary drivers for your gfx card and use their tools to make it work for you.

Below are some of my own notes on the topic, use them at your own risk ;). I have a IBM T40p with a ATI Radeon RV250 [Mobility FireGL 9000] (sudo lshw -C video).
