I'm running four Arch machines: three laptops (x86_64), all of them with LXQt DE launched from SDDM; and one very old desktop PC (i686) with spectrwm WM, launched by startx command.
Recently, only in my Arch + LXQt machines I'm experiencing a strange issue: when logged user requires shutdown or reboot executed from LXQt graphical menu, or by systemctl poweroff / reboot commands in qterminal, the systemd poweroff/reboot process is delayed, showing message "a stop job is running for Session c2 of user xx (Xs / 1min 30s)".
However, performing an user logout from LXQt menu, and afterwards executing poweroff/reboot command from SDDM-greeter buttons or from another tty, systemd goes ahead smoothly.
BTW: in my Arch + spectrwm machine I don't have this issue: $systemctl poweroff/reboot command in urxvt under user session performs its task without problems, user don't need to kill spectrwm nor switch to another tty to execute it.
I don't know if the shutdown/reboot issue resides in LXQt or in SDDM routines, but it seemed that user session isn't shutted/killed correctly from LXQt shutdown/reboot menu, and systemd waits to complete precaution time before kill LXQt/SDDM remaining processes.
To dodge this issue, I managed to don't show options other than Leave -> Logout on LXQt menu, but... it isn't a real solution: a logged user must be able to perform a shutdown or reboot command.

Is anyone suffering similar troubles? Could anyone confirm my suspection?
Must I file a bug to LXQt or/and SDDM developers? I'm pretty sure that isn't a Arch Linux bug...
Best regards,

P.S.: forgive me my bad english, I'm argentinian and only speak spanish.

Hi Daniel,
I believe I am experiencing the same issue and I have filed a bug report at the LXQt site.
Maybe you can add your experiences and information to it, increasing the need for a fix and adding hopefully missing information?
lxqt-panel: reboot takes a long time

@Arthur:
First of all, please forgive me for my delayed reply to your tips on this bug.
Thanks for your advise!
Now I'm following https://github.com/lxde/lxqt/issues/1311 , it seems a very complicated issue and out of my knowledge scope...
I'm still dodging this bug, closing LXQt session by Logout and then shutting down my system by Poweroff button in SDDM greeter.
BTW: one of my notebooks, wich have SDDM and automatic login, I had to disable Relogin in /etc/sddm.conf to allow execute Logout properly:
# Whether sddm should automatically log back into sessions when they exit
Relogin=false
....I hope LXQt developers can solve this issue soon.
LXQt is my last choice on DE, I've already used KDE, GNOME, MATE, XFCE (bloated and heavy things, I think).
LXQT is lightweight, visually clean, and Qt based: the vast majority of apps that I use runs using Qt(4|5) framework.
A very few exceptions: KiCAD, Arduino, Audacity, Usbpicprog (for my work); Chromium (rarely, I prefer Qupzilla), Linphone, Xsane, galculator, gucharmap, blueman (general usage).
Best regards,
Daniel.
