After having updated Kubuntu from 16.04 (with kubuntu backports ppa enabled) to 16.10 my keyboard does record only a few keys (it ignores most keystrokes).
This happens only in plasma (e.g. Krunner, Application launcher,password dialogues). However, this does not happen in the terminal and in applications (e.g. Libreoffice, firefox, guake, telegram, plasma-discover, kate).
The behavior is irrespective of the keyboard layout chosen (DE,GR,US)
Nonetheless it is very annoying as
- I am used to using Alt-F2 + typing to open my applications
- I cannot run any GUI applications requiring root (e.g. my own scripts to mount my work network places into my filesystem)
What I have done
Deleting all files under ~/.config
containing plasma by running rm *plasma*
did not change anything.
Similarly, deleting all files under ~/.cache
containing plasma by running rm *plasma*
did not change anything.
When I run
killall plasmashell #to stop plasmashell
kstart plasmashell #to restart plasmashell
killall krunner #to stop krunner
krunner #to start krunner
and the following to restart polkit-kde-authentification-agent-1
killall polkit-kde-authentication-agent-1
/usr/lib/x86_64-linux-gnu/libexec/polkit-kde-authentication-agent-1 &
as described in this bug, the aforementioned problems seem to be resolved.
However, they reappear on each restart. Any ideas?
