So you want to SWITCH to Kubuntu and want to know if the same errors will occur?
I assume (guessing here) that since it uses ubuntu that if you download,install, and run that yes you will get same errors. It is most likely your hardware and some new drivers ubuntu chose to use.
I have Zorin (Built on ubuntu) and I got the same errors with updating to 11.04 as others (broadcom wi-fi not working for example) so anything assembled on top of Ubuntu will probably still behave just as Ubuntu.
As far as get a Debian based distro ... Go for it ... It's fun ... But be prepared for a less 'basic' experience. If you don't like the one you are using ... Try a new one ... You're bound to find something that you like that works well with your computer setup.
