Comment 1 Lester Caine 2015-10-28 20:11:10 UTC

I currently have a working setup, but not entirely sure how I got here ...
The kscreen display is now working and allowing management of the 4 screens, which is useful since when I reboot it looses the order of the screens and stacks two on top of one another. Once repositioned I then have to change the primary screen before the apply button is activated. It is not activated by the position changes.
I suspect that until I had an more complete config file kscreen was crashing, but once I'd manually played with settings that particular problem has cleared.
(Bug 353904 is a previous crash report)

Sorry for the late response.

The backtrace is lacking debug symbols. We see that it crashed, but not where and why.

By now the version you used is no longer maintained (also wasn't when you reported the bug). The software has changed a lot. If you still experience the crash with the latest version (5.7) please report a new bug.
