Summary: kwin crashes when using xrandr to configure dual-head
Product: kde
Version: unspecified
Platform: Ubuntu Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: dualhead
AssignedTo: unassigned-bugs at kde.org
ReportedBy: danbohr at gmail.com
Version: (using KDE 4.1.2)
OS: Linux
Installed from: Ubuntu Packages
The installation is a Kubuntu Interpid Ibex, 64 bit kernel on a Lenovo X61s
with all updates from the Kubuntu repositories.
I can trigger the crash by issuing
xrandr --output LVDS --mode 1024x768 --pos 0x0 --output VGA --mode 1024x768
--pos 1024x0
which switches on the second monitor correctly, but also makes KWin crash.
Here is the (full) backtrace from the KDE crash handler:
Application: KWin (kwin), signal SIGABRT
