how to set screen resolution properly on my Kubuntu-laptop???

[Magyari, Balázs]

Unfortunately I had no success commiting the changes in xorg.conf :-(
The only option is still 1024x768. Should I do something in the System
Settings => Display => Hardware tab?

> Yes, you got it correct. However, it's always a good practice to backup a
