My display is 1280X800. Any help?

I dunno if this will help you or not, but when I used to have problems with my 1680x1050 monitor I'd backspace the other res settings on the Modes line under Section "Screen" so it had no other option but to use the correct one. I have no idea if that will work for you or not but its something to try.

You could try switching to the i810 driver instead of using the intel one. There is also an updated i810 driver available in the testing repos.

Driver is installed correctly, it's just that it won't display the correct resolution in display manager and everything is off by an inch on the right and half inch from the bottom. My login screen has a black edge around it. And if I enable compiz or berryl that area is also black. I tried downgrading to i810 driver, it fixes the black edge, resolution is still 1024x768 however everything looks out of focus and 915resolution refuses to work.

I am not sure if I got the updated i810 driver from test repo. But I just downgraded again to i810 after installing i810 development driver. It fixed my border issues and it's not blurry however I still can't set my resolution past 1024x768. Ran setup set my resolution to 1280x800 in Xserver it still show's up as 1024x768. I don't understand what the problem is, I had no problem's running correct resolution in Fedora 6 or Ubuntu 7.04. I run into the same problem with Ubuntu 7.10, Fedora 7 and OpenSuse 10.3. Any more suggestions?

If you have one of the older live CDs, boot it up and try copying the older xorg.conf file to see if the newer distros display right again.

After messing around with the i810 driver, I think I used the updated one from Fedora Test repo. I got the correct resolution working, my display manager now reflects 1280x800. I got desktop effect's running flawlessly. However I can't get dual head to work now. Is there some kind of special configuration I have to do with i810 driver. I know with the new intel driver dual head work's out of the box, no tweaking is necessary. Any suggestions?

I've never really played with dual head driver capability. You could try searching the forum on dual head and looking at other's xorg.conf to see if you can't find something that'll work.
