kubuntu display resolution

Hello. Im running kubuntu on a pc with 6 MB of ram and 500GB hard drive. My processor is an AMD Athlon II dual-core, 2.9GHz. I also have a NVidia GeForce GT 430 video card and an HP 2310m 23" HD Widescreen monitor.

After a fresh install of Kubuntu, the resolution was correct but it didn't recognize my monitor. (not a big deal). But after I enabled my NVidia card (via hardware drivers screen) I did an apt-get update && upgrade, and reboot, I end up with an unrecognized monitor and the highest resolution it will let me pick is 1024x768. I should be running 1920x1080.

Does anyone know how to adjust the resolution back to 1920x1080? It may involve editing my /etc/X11/xorg.conf but I have no clue how to do this properly.

Can you post your "/etc/X11/xorg.conf" and output of command "xrandr". Also what about resolution setting in application "systemsettings" / "Display and monitor", did you changed it?

Kernel Upgrade caused the problem

Hello. Thanks for the help. I reinstalled everything and was careful to activate my NVIDIA driver AFTER updating and upgrading. This fixed the problem. Apparently in the upgrade there was a kernel upgrade that was not comprehended by my video driver.
