Hi *,
on one of my machines (Lenovo T420 notebook) I have a problem with
plasmashell freezing often when a notification is shown. The
notification frame shows up, but no content and then the complete
desktop freezes. Killing and restarting plasmashell cures the problem
for a short time - til one of the the next notifications wants to
display something. It doesn't happen for all notifications, though.
Using tools like notify-send the problem can not be reproduced, but
notifications stemming from plasma-nm and plasma-workspace itself (like
the one for a removed plasmoid) always lead to the freeze.
The system originally was openSuSE Leap 42.2, but because of the problem
I upgraded step by step to
- the latest kernel from the kernel stable repo,
- the latest X server plus everyting from the X11:Xorg repo
- and the latest plasma workspace including everything from the
KDE:Framework5 repo.
The problem remained unchanged, though.
A few more facts:
- The X server is xf86-video-intel.
- Switching off the compositor doesn't help either.
- Everything worked with Leap 42.1
- No according entry in the journal or .xsession-errors* can be found.
- And a curiosity: After removing .config/plasmarc and restarting
plasmashell the problem vanishes for a few hours or even a day, before
it comes back.
- Logging off or restarting the machine doesn't help in case the
problems exists at that time.
In found a few bug reports for plasma freezes, but none of them seems to
fit exactly.
Is this a known problem?
Can I debug it and if so, how?
TIA.
Bye.
Michael.
