Description Javier 2015-01-23 17:24:08 UTC
Application: plasmashell ()

Qt Version: 5.3.2
Operating System: Linux 3.18.0-9-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I just closed XBMC, wich was running on full screen. Also at barely the same time also krunner crashed.

- Unusual behavior I noticed:
I have two monitors hooked up, one VGA and the other DVI. Even though in KDE I have set up the DVI monitor as the primary one, when lunching XBMC in full screen mode it shows on the VGA.
When entering and exiting this full screen mode the screens blink and it is visible that they have been switched (in the DVI FHD I can see an area the size of a 1024x768 (the VGA) and the rest black, and the oposite on the VGA).

Using a fully updated Kubuntu 15.04 + proposed repos.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault

Which 'upstream' does the resolution refer to? I'd like to take it up with them, whoever they are.
Comment 6 Marco Martin 2015-05-20 10:03:05 UTC
the first crash seems in plasma stuff (Applet::actions()) and many other similar reports arrived

Note that only the second backtrace reported here is a duplicate of bug 345544, which turned out to be a crash in Qt. The backtrace in the original report is a crash in Plasma, which I also experienced after connecting a new monitor while the screen was locked.

I also got this crash (the first backtrace) on Arch Linux with Qt 5.5.1. Why was this resolved as a duplicate of another bug if it's not the same backtrace?

The backtrace I got when switching monitors

I got this crash when doing

[estan@pyret ~]$ xrandr --output VGA1 --off && xrandr --output LVDS1 --auto
[estan@pyret ~]$ xrandr --output LVDS1 --off && xrandr --output VGA1 --auto

while connected to my external monitor. I.e. switching to the laptop internal monitor, and then back to external monitor. The crash happened on the second command. Sorry for the lack of debugging symbols, not sure how to get those on Arch.

The effect on fonts after the crash

As a side effect of the crash, something happened to the fonts in certain parts of the system. They became huge. The attached screenshot shows the effect.
