My laptop (Dell Inspiron 9300, Slack 10.1 w/ various upgraded packages) has been configured for a dual screen configuration for a while. I use the laptop screen itself, then plug another screen into the VGA port on the back. It's been working great up until a week or two ago. Admittedly, the problem seemed to begin when I started plugging the laptop into my new LG 42LG60 TV at home- but it's now happening even on the monitor at my office that I've been using without problems for 6+ months.
What's happening is that when I start KDE, KDesktop crashes on (and only on) the second monitor (the external): "The application KDesktop (kdesktop) crashed and caused the signal 11 (SIGSEGV)"
The taskbar usually stays on the screen, but the desktop itself is gone- leaving only the grey x.org background. I *can* launch applications from the taskbar on the second monitor- but they don't appear in the taskbar itself once loaded. I merely assume this has to do with KDesktop crashing.
I've looked online and through the forums for a similar situation, but everything I find seems to be related to some other program causing the crash. Everything I have loading on the second monitor desktop is also loading on the laptop monitor without problem, so I don't believe it is a problem with an application.
It seems odd, though, that it would spontaneously start happening when nothing has really changed on my system. I MAY have upgraded a library (like Qt) or something, but I certainly haven't done that in the past few weeks.
So I'm left scratching my head on what exactly is going on and how to go forward to remedy it without completely reinstalling KDE.
I have captured some output- first, the output after running 'startx' (captured using "startx &> xout.txt"). Going through, I found a few things that seemed to reference the crash:
Code:
DCOP aborting (delayed) call from 'anonymous-7991' to 'kdesktop-screen-1'
DCOP: unregister 'kdesktop-screen-1'
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = kdesktop path = <unknown> pid = 7992
kdeinit: Got EXEC_NEW 'drkonqi' from socket.
Could not load library! Trying exec....
kdeinit: PID 8011 terminated.
ERROR: Communication problem with kdesktop-screen-1, it probably crashed.
DCOP: unregister 'anonymous-7991'
... there is a LOT more captured output- not sure if any of it is relevant or not, but due to the post size limitation, I'm only posting what I've found. Everything around this bit of output seemed to reference kweather. I can certainly most more if requested.
Secondly, I have output from the KDE Crash Handler backtrace:
Code:

I looked at my Xorg logs and didn't see anything that stands out as an error. I can post it if requested.
Anyone have any insight into what could be causing this and what to do about it?
Help is very much appreciated!
Thanks!
