Public bug reported:
After upgrading from Intrepid to Jaunty recently, I found that my laptop
internal screen resolution is wrongly detected, when it is mounted in a
docking station. In Intrepid with KDE 4.2, it used to work just fine and
no configuration change was needed. Unfortunately, since I have
upgraded, I couldn't get the log file from Intrepid, where it was
working fine !
