The native resolution is 1680x1050, but Ubuntu shall recognize it as 1600x1200, which squishes it vertically. Still works though great though, and it's worth it for a few more pixels.

After much research on installing the NVIDIA driver for my GTX-650 GPU, I see that the Nouveau driver is pre-installed. I don't need 3D graphics and will continue to use the default driver.I'm using an Acer monitor w/ native resolution of 1600x1200 pixels.
Kubuntu 9.10 Almost everything works great: Bluetooth, Wifi, card reader, 1680x1050 screen resolution, graphics composting, video out. Not tested: suspend, hibernate Not working: ATI graphics driver has trouble with 3D apps: Celestia, Google Eart...
My friend has a custom-built desktop/tower that runs Fedora and Ubuntu. Both have a similar problem: we can not get the resoltion any higher than 800x600. We have an Acer V223w with top resolution of 1680x1050.
After a lot of googling, this is my last resort. I recently upgraded from 12.04 to 12.10 (64bit) and now my secondary monitor cannot be set to its native resolution (1920x1080) or to my preferred resolution (1680x1050). However, I can set the monitor to any resolution below 1680x1050.
I have a radeon hd6950. I tried using xrandr to force the appropriate mode to no avail.
