Description Axel von Bertoldi 2015-06-17 14:11:32 UTC 
Application: plasmashell (5.3.1)

Qt Version: 5.4.2
Operating System: Linux 4.0.5-300.fc22.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
pressed Alt+Shift+F12 as is a new install
- Unusual behavior I noticed:
previously could not login, sddm did not accept keypresses (some letters)
- Custom settings of the application:
did startx from a virtual panel and could get into a GUI where changed some settings (to my default)

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 David Edmundson 2015-06-17 14:59:14 UTC 
Thanks,

We've not seen this crash before, so I'm going to have to request some more information from you (sorry). Can you install debug symbols for libepoxy and kdeclarative?

Also this isn't a direct crash, but throwing a fatal error message, could you run "plasmashell" from the command line and copy and paste the last few lines.
Comment 2 Axel von Bertoldi 2015-06-17 17:27:13 UTC 
Hi David,
sorry about the delay but I hat to reinstall Fedora 22-KDE because I had a problem installing the debug symbols for kdeclarative. I had the updates-testing repos enabled, and one version higher on kdeclarative. Downgraded to the lower version and then hell broke loose. Decided that it was going to be faster to reinstall Fedora.

I've had problems since yesterday first install using the live version of F22-KDE. Tracked down to sddm-greeter, which did not let me login, at the second letter of the username it crashed showing an empty X window but I could login in a virtual console, and there could see that the keyboard was not the problem.
After a few reads about this problem I found somebody advised to run 'startx' and from there thing went smoother.

And then I started getting those bugs...

Now, after reinstalling and slowly changing things to my liking did not reproduce those bugs. If they reappear I will let you know, and might be able to show what I did to cause them. For now I will not enable  updates-testing

Kind regards,

Comment 3 Axel von Bertoldi 2015-06-17 18:30:13 UTC 
Well David,

It happened again. Was installing a bunch of programs and wanted to add applets. Did add one, and when selected the second one, 'CPU Load Monitor' mouse and KB froze. On reboot, I go straight to my account (autologin selected in Sistem_Settings > Startup&Shutdown > Login Screen (SDDM).  BTW, something to note here, the figure (icon) for Login Screen (SDDM) has a warning triangle on top of the icon.

As I said, direct to my account, need to do the Shift+Alt+F12 to show the toolbar and after a few seconds the three bugs show up. After closing the third panel, screen goes dark, cursor still responsive. If I do Ctr+Tab I can see the shadow where the applet selection was after reboot (left side of screen like full height by 5 cm, left monitor of a dual 22" monitors).
Go to tty3, login as other user, startx and I am in, but still need to do Shif+Alt+F12.
I go to tty2, login as myself and do startx and get the same black screen and no cursor nor keyboard.
Hope this helps.

p.

Comment 4 Axel von Bertoldi 2015-06-17 18:55:05 UTC 
Dave this will be the third installment ;)
After rebooting, I went right into a black screen with the layout of three panels, I know they are the big reports with the only visible button 'Close'. 
login as myself on tty2 and run 'plasmashell', output is only two lines:
QxcbConnection: Could not connect to display
Aborted (core dumped)

Is there a switch to plasmashell?, I tried the man page but the is no manual entry.

login as other user on tty3 and run yumex extender to install the debug symbols for libepoxy and kdeclarative, but they are not in the standard repos, will look around, but on the meantime could you send me the link?

Comment 6 Martin Walch 2015-08-13 21:21:08 UTC 
Created attachment 94022 [details]
backtrace

This looks very much like my crash. Happens every time when I add a network monitoring plasmoid to my desktop. In plasma-org.kde.plasma.desktop-appletsrc it shows up with

 [Containments][7][Applets][16]
immutability=1
plugin=org.kde.plasma.systemmonitor.net

I am using an exotic configuration with two different rather old graphics cards. The problem might be related to the nouveau driver. However, I did not experience such crashes on KDE 4.

(Strangely, I cannot add this backtrace using DrKonqi as the button "Suggest this crash is related" won't do anything.)
