[Bug 342904] Re: [i945] Kubuntu Jaunty - HP/Compaq nc6400 laptop, Intel 945 GM, screen resolution wrongly detected when mounted in docking station

[Musthafa Meeran]

Hi, I am sorry to say that I am currently not using Jaunty due to some
graphics performance issues of the newer xorg/intel drivers and I am
using Intrepid now. So I couldn't get the required data now. I ll do
it once I have upgraded to Jaunty. Can we keep this bug open till
then?

Thanks a lot...

> 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 !
