Lxqt-leave reboot and logout do not work

[roman-buntsevich]

Expected Behavior

System reboot or shutdown after I pressed corresponding UI button (or input a command from a terminal).

Current Behavior

When I press Leave -> Reboot or Leave -> Shutdown nothing happens (visually). Also I can't use commands from content of .desktop files in terminal - I get an error

roman@debian:~ lxqt-leave --reboot
** Dbus error **************************
Error name "org.freedesktop.DBus.Error.AccessDenied"
Error msg "Permission denied"

---

systemd: "CanReboot" = "Permission denied"
dbusCall: QDBusInterface is invalid "org.freedesktop.ConsoleKit" "/org/freedesktop/ConsoleKit/Manager" "org.freedesktop.ConsoleKit.Manager" "CanReboot"

Possible Solution

As workaround you can use systemctl (from terminal or with edititing Exec /usr/share/applications corresponding .desktop files).

Steps to Reproduce

Install fresh debian 9.6 stretch from netinst iso (https://www.debian.org/CD/netinst/) and programs from the list below with apt-get install --no-install-recommends, reboot and login to LXQt session.

Context

This is very annoying and strange issue. I have tried solutions from google search result but nothing helped. I am sure I did everything right during software installation, so this is a definitely unexpected behavior.

System Information

• Kernel: Linux debian 4.9.0-8-amd64 compile lxqt-panel, error..., What package should be installed, but sysstat lib is installed. #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux
• Qt Version: don't know how to find out, mostly installed llibs' names end with qt5
• liblxqt Version: liblxqt0/stable,now 0.11.1-1 amd64 [installed,automatic]
• Package version: lxqt-core 13

not an upstream issue - and not a debian issue. And there is nothing we will fix neighter in upstream nor in debian. My vague guess is that you had installed the lxqt-core meta package with --no-install-recommends. if so - it was your decision so only you had to deal with it.

It might sound harsh - but this is called reality. Another hint: If one would install the "bloated" lxqt meta-package it would work.

More verbose: The meta-packages currently in stable are really stripped down to the point where nothing left to remove. And core is meant as the LXQt core - after we had experienced the users forcefully wrecked their installations we changed both lxqt and lxqt-core to make it more "user-proof" aka we added packages that are not really dependencies to the dependencies just to have a working system the most users would expect to have after an fresh installation.

So yes - i use my maintainer super powers to force working installations upon the meta-packages users. I really know and admit that i'm a very bad guy.

PS: at least one want to install lxqt-policykit or any other pk-handler to have the needed rights as a user to perform tasks like shutdown or reboot - obvious, isn't it?
