plasma panel sometimes hangs, becomes irresponsive. this is preceded by some notification appearing in the notification area, that becomes stuck in the corner of the windows and cannot be dismissed. at the same time all the panel becomes irresponsive to mouse clicks. my only workaround is killing plasmashell.
Hello Fulvio, have you possibly kdeconnect installed and those notification, as far as they are still readable, are related to a connected Android phone? Then this upstream issue might be related: https://bugs.kde.org/show_bug.cgi?id=442645 I ask because I have kdeconnect installed and see all some days such a hang you are describing. (But I don't get a call like in above upstream bug, it is just notifications.) I am able to "free" my session by this sequence from SSH or virtual terminal session: killall plasmashell killall kwin_x11 export DISPLAY=:0 plasmashell --replace & kwin_x11 --replace & (But unfortunately that environment is not exactly the same so a restart of the session might be still a good idea, or repeat from a still running konsole window with a good environment ...) I generated a core file via gdb last time for both processes, but when I inspected it now I did not see an obvious interesting thread... Kind regards, Bernhard
