Kubuntu Jaunty - plasma crashed with SIGSEGV, when laptop mounted on docking station

[Musthafa Meeran]

Yesterday I updated from Intrepid to Jaunty, since I very much like KDE 4.2. It was working smoothly in Intrepid, but after upgrading to Jaunty, I encountered the following problems.

Reporting a new bug, since the bug raised by apport (plasma crashed with SIGSEGV https://bugs.launchpad.net/bugs/342223) was closed automatically !!

When my laptop is mounted in the docking station, the laptop screen resolution is wrongly detected as "1152x864" instead of the original "1440x900" (in kdm as well as after login). When not mounted in docking station, it is correctly identified.
This was working fine in Intrepid with KDE 4.2.

And KDE always starts with no plasma and black blank screen. When I try to start plasma using krunner or konsole, it crashes. But it starts without any problem, when not mounted in docking station.
Again, this was working fine in Intrepid with KDE 4.2.

So, it looks like a problem with the new kernel or the xorg video driver, which I am not sure.

The duplicate bug #338205 says that the plasma crash issue is resolved.

But the wrong screen resolution issue still remains.

Could you please have a look at this bug from this perspective and help me out with this?

Thanks in advance...

It says fix committed, not fix released. (which would be resolved)

[Musthafa Meeran (musthafameeran-deactivatedaccount)]

Hi, sorry, pardon me for using the wrong terminology.

Do I need to report a new bug for the screen resolution issue?

Thanks a lot....

[Jonathan Thomas (echidnaman)]

You would want to report the resolution issue separately.

[Musthafa Meeran (musthafameeran-deactivatedaccount)]

Thanks a lot, will report separately.
