I gave a friend Knoppix 3.6 to try on his Windows PC.
It booted fine yet the KDE desktop is "shifted" to the right in a manner
that makes the main menu button unseen (and thus the system -menuless).
My friend won't use the monitor's control (as it affects Windows too).
I have tried xvidtune to find out that the (integrated) graphic chip does
NOT support video tuning.

Please advise how can I drag to desktop to a useful position?
