I did sudo apt-get remove nvidia-glx-legacy
Then I installed restricted manager and I used it to enable NVIDIA propr driver.
I rebooted. I got empty screen so I shut down kdm via /etc/init.d/kdm stop.
Then I tried to "startx" and I got "API mismatch: NVIDIA kernel module version 1.0.7184, and X module version is 1.0.9631", so I looked into /lib/linux-restricted-modules and I found ".nvidia_new_installed" file. I removed that file and tried startx again. X Window started with correct acceleration!

Then I logged into my user account and while the display was 1920x1440 the refresh rate was very poor. Kubuntu configuration revealed I run at 56 Hz and the only other option was 50 Hz. After some experimentation I found that after switching to 50 Hz the monitor appears flicker-free. Somehow, although KDE KControl says that it runs at 50Hz it actually runs at 75 Hz.

Thank you for your help. I still believe that this is an error because a novice would hardly be able to resolve this.
