Screen resolution doesn't change?
 

Plz help me! I have dell optiplex gx260, intel i810 video card, ubuntu lts and my screen resolution doesn't change. I'm using Xorg. I don't know what to do, I have looked for information about that problem for weeks.. But nothing helped me. My current resolution is 640x480 and thats pretty disturbing if you can imagine.. :) Somebody please help me!

Look at post 10 of this thread. I was having the same problems a while ago, but with this command I was able to fix it. Try that, and tell me how it works.
