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 (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) [Thread debugging using libthread_db enabled] [New Thread 0x7f9cb511c700 (LWP 7506)] (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) (no debugging symbols found) [KCrash handler] #5 0x00007f9cb4931fd5 in raise () from /lib/libc.so.6 #6 0x00007f9cb4933b43 in abort () from /lib/libc.so.6 #7 0x00007f9cb3c916b5 in qt_message_output () from /usr/lib/libQtCore.so.4 #8 0x00007f9cb3c917fd in qFatal () from /usr/lib/libQtCore.so.4 #9 0x00007f9cb4cdc747 in ??
