Description Gerion 2014-06-18 23:05:54 UTC 
Change the title, if you find a better one. The last time I started plasma, only the left edge of the desktop were rendered. I take a few pictures and video, so you can see the problem by yourself.

I start plasma always per terminal with this command:
startx /usr/bin/startkde

Reproducible: Sometimes

Steps to Reproduce:
1. Start KDE.
Actual Results:  
You see only parts of the gui.

Expected Results:  
You see a normal desktop.

I'm not sure what component causes this bug. It could be, that kscreen is responsible. I have a multimonitor setup, but use the second monitor only sometimes. kscreen seems not to be good in storing this two types of settings: "second monitor on", "second monitor off" and switch smoothly between this two.
In this case the second monitor was off (during boot, too). (In the previous boot process the second monitor was on, but not kde, only X.)

Unfortunately I missed the log. Next time the bug occurs, I will attach a log. This problem is not really reproducable.

Argh, the video upload does not worked as expected.
Try this one: http://www.vidup.de/v/oFWPz/

Yes this happens sometimes even when logging with sddm/lightdm.. but not really problem that one can reproduce..

Are you able to open a konsole

try:
 DISPLAY=:0 konsole from a TTY

if so can you give me the output of "xrandr -q "
and "qtdiag"
Comment 4 David Edmundson 2014-06-20 14:32:13 UTC 
Do you by any chance have a rotated screen?

I never had or have a rotated screen. On a working setup the output of xrandr -q is:

The problem occurs again. This time I logged it. See the attached log (I stopped X with CTRL-C).

Comment 8 Aleix Pol 2014-06-24 18:49:46 UTC 
The log you sent looks more like something crashing rather than an actual problem of workspace management.

Adding Martin Graesslin as CC.
Comment 9 Gerion 2014-06-24 19:37:01 UTC 
See the other attached log. This is a normal startup.
Some crashes were caused by typing CRTL-C I think. E.g. yakuake crashes each time I close the session (known bug).

Comment 11 Martin Klapetek 2015-05-13 14:30:47 UTC 
Is this still happening with newer Plasma (5.3 ideally)?
Comment 12 Martin Klapetek 2016-02-03 20:54:24 UTC 
No response to comment #11, assuming fixed.

If you can still reproduce this with Plasma 5.5, please
reopen this report.

Thanks
Comment 13 Gerion 2016-02-03 22:52:05 UTC 
Sorry, I don't get it. The issue is gone since much versions. Thank you, too.
