[EN] LXQt, lxqt-panel process fails to stop
« on: 2017/12/27, 00:05:55 »
I have reproduced this issue a few times on my LXQt system.


Code: [Select]
systemctl isolate multi-user-target

closes most user processes, but fails to close lxqt-panel.


After running full-upgrade or whatever in the console session you issue


Code: [Select]
systemctl isolate graphical-target && exit

The LXQt desktop fails to start correctly.


If, however, while in the console session you kill -9 the user process for lxqt-panel, then you can restart the LXQt desktop with
Code: [Select]
systemctl isolate graphical.target && exit

Here is my system:

Code: [Select]
lxqt-leave --reboot

you are just to impatient to wait 1'30" 8) - and it is not the panels fault - it is the menu-cached - systemd don't end this daemon right, might be another bug in the menu-cache daemon. lxqt-leave close the needed processes and invoke the action after ...

Edit: I don't know why one will use systemctl isolate - it is a mis-use, it would be enough to open a console and run the updates there or just stop the dm - systemctl stop sddm.

Heh -- OK, thank you.  It seems the old dog needs to learn a new trick!   :D
