Well, it's quite early in the morning here, so, I'm too tired and lazy to have read all of your posts. :P
Anyways, I don't think the screen on the AspireOne can do 1024x768. Reason being that, when I first plugged in my external monitor, it was 1024x600, and stretched to fit the whole screen. You can imagine, it was ugly beyond...ugly. Since I haven't used Linux before I got my AspireOne, I didn't know how to change the screen resolution. At last, I figured out that you open Run Program, type in
and then the external monitor will display as 1024x768. At least, for mine it does.
Once I did that, the AspireOne no longer displayed the screen. But it was set as mirror screen mode, both screens on. And when I typed
to go back to the original resolution, the AspireOne's screen went back on, and my external monitor went ugly again.
So, basically, I don't think the AspireOne's screen is capable of displaying 1024x768. External monitors are cheap now. 17" LCDs are about $150, $100 if used.
Good luck!!
