xorg.conf file used with nvidia driver.

Description of problem:
I installed the nvidia driver.

Then I want to login using kde plasma workspace, but it gets stuck at step 2 of the splash screen (the setting tools) and i never get logged in.
I have to ctrl-alt-backspace to come to the login screen.

If I uninstall the nvidia driver, everything comes back to normal and i can use the kde desktop again.
