Bug#1000955: libkf5globalaccel-bin: /usr/bin/kglobalaccel5 eats up huge amount of CPU after suspend
Package: libkf5globalaccel-bin
Version: 5.78.0-3
Severity: critical
Tags: upstream
Justification: breaks the whole system
X-Debbugs-Cc: lopippo@debian.org
Greetings,
it is now a reproducible fact that my Plasma session goes awry in two different
situations:
1. When I plug in a headphones+micro (LogiTech or Jabra) with a USB connector;
2. When I suspend my laptop using the "Moon" keyboard key.
In both cases my Plasma workspace session gets unresponsive as far as the
keyboard is concerned. Interestingly, the keyboard still catches strokes *only*
when I type the Ctrl+Alt+F2 sequence to get out of Plasma and reach a console.
In that console, I run htop and I can monitor that /usr/bin/kglobalaccel5 eats
almost a third of the CPU (37%). I tried to kill (9) the process but it is
recreated anew and eats the same amount of CPU.
Note that I also see a huge CPU consumption for the following processes:
/usr/lib/xorg/Xorg (63%)
/usr/sbin/rsyslogd (14%)
/lib/systemd/systemd-journald (10%)
Yeah, I know these percentages sum up to > 100 :-(
I have to to specify that the case 1. does not happen when I am running not
Plasma but Gnome (Wayland).
Should I install other packages to fix the problem? What can I do to help?
Sincerely,
Filippo
