How to change the screen resolution?

I have been trying to connect the new aspire one with an external LCD 3:4 monitor for 2 days. The screen in the external one is always 1024x600 which looks so bad. Can someone change Aspireone's sreen resolution on Linpus?
Thanks

 

I doubt you can do this easily without digging in some config files. So far, the only thing I dont like about the Linpux Lite distribution is that its dumbed down a little too much. I understand that they make it where you can't easily mess up the system, but when is enough enough. I guess thats why I installed Ubuntu, which gave me a lot more flexibility as to how my system looks and feels.

 

Bdogg64, you are right. I change the resolution to 800x600.
All I did is to change the sreen\Virtual subsection in xorg.conf from 1024x600 to 800x600, then restart.
The problem is that the desktop is messed up, but it looks on an external 4:3 monitor.

 

I tried this but when I save the file I get a "Can't open file to write" error. Any ideas?

 

Madison, try to open it through terminal but logged as root (command "su")
And one thing... Can I make the resolution bigger instead of lower? Thanks.

 

Thanks. Works now. I didn't know you had to do everything from the terminal.

I changed the virtual to 800x600, but when I restart without vga plugged in, the One is displaying at 800x600 instead of 1024. I can change the virtual setting back to 1024x600, but I'd like to not have to get root access every time I want to use an external monitor. I've been looking for a thread I saw a couple weeks ago before I had my One but can't find it.

Any solutions?
