[Bug 318418] [NEW] kwin crashes after enabling external VGA output

[Florian Auer]

Public bug reported:

Binary package hint: kdebase-workspace

My system is a Lenovo T61 (for details see attached sysinfo.txt), I'm
using [K|X]ubuntu 8.10 with KDE 4.2 packages from
"http://ppa.launchpad.net/kubuntu-experimental/ubuntu intrepid main".
Using XFCE the desktop size gets automatically adjusted to the VGA
monitor's resolution (1280x1024 at 60Hz) after logging in.

What I expected to happen:
Display gets automatically adjusted to 1280x1024 at 60Hz as it is done in XFCE.

What happened instead:
When I log in to KDE, the resolution stays at 1400x1050 at 60Hz, and when I try to change to 1280x1024 at 60Hz with xrandr or krandrtray (enabling the VGA port and disabling the laptop's LVDS display, see xrandr.txt for details) kwin crashes and my desktop is white, no task bar, no desktop widgets, no icons.

I don't know if this is a duplicate of bug #291445 as I don't have a
nvidia card...
