Description Mike Swierczek 2015-07-28 12:50:02 UTC

Description of problem:
If I leave my machine for a few hours and come back, when I unlock the screen my KDE desktop application title bars are not displayed.  The rest of the window is present, and my KDE panel, but not the title bar.  I also cannot move, minimize, or maximize windows and the last window that had focus is the only window I can interact with.  I have to do Ctrl+Alt+F2, login, and then as root restart sddm.service or reboot the machine to get normal functionality.

Version-Release number of selected component (if applicable):
Not sure which KDE or Xorg or kernel component is responsible.

How reproducible:
Happened twice in 24 hours.

Steps to Reproduce:
1. Log in to KDE desktop and open a few applications.
2. Lock screen and leave.
3. Unlock screen.

Actual results:
As described.

Expected results:
Normal desktop behavior.

Additional info:
I'm not sure if this is relevant, but I have a laptop in a docking station and external monitor.  The onboard graphics are Nvidia NVS 5200M and I'm using the latest proprietary driver.  (I had periodic hanging problems with the nouveau driver.)

I looked through dmesg and used "journalctl -r" to examine the logs for errors, but if there was anything related to this problem I could not find it.

Comment 1 Rex Dieter 2015-07-28 15:26:01 UTC

sounds like kwin crashed (often caused by video driver issues).

For user logs, look in ~/.xsession-errors

In the meantime, to workaround kwin missing you can try re-running it via krunner:

ALT-F2:  kwin --replace

Comment 2 Mike Swierczek 2015-07-28 15:35:50 UTC

I've done some more hunting about the error, and it may be related to this xorg bug: https://bugs.freedesktop.org/show_bug.cgi?id=91316  

So rather than burn more time on it, maybe it makes sense to wait for the next xorg package release and see what changes.

ALT-F2 kwin--replace got me a fresh desktop, thanks.  Is that better than restarting the display manager, or just a different means to the same end?

Comment 3 Rex Dieter 2015-07-28 15:39:17 UTC

Not sure what you mean by "restarting the display manager".  kwin is the *window manager* here, if that helps.

Otherwise, without a backtrace (or drkonqi/abrt report), it's hard to speculate on what's going wrong here.

Comment 5 Fedora End Of Life 2016-07-19 17:13:58 UTC

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
