LXDE on Antix22: “No session for pid…” and no Shutdown in Logout

[Member Harlem]

Good morning,

LXDE on Antix22 intermittently generates a “No session for pid…” error and, on Logout there is no option to Shut the system down.

That error, and the ‘missing’ shutdown error does not happen in LXDE on MX-19.4 on this hardware:

but it is happening on another Lenovo T500 being used as a test bed for Antix 22.

Looking around the web I’ve found that the “No session for pid…” error apparently has a history going back quite awhile (2014?) but I’ve found no applicable resolutions (Ubuntu doesn’t count) so I am wondering if there’s a known solution to both the “pid” error and the’no shutdown’ option.

TIA,

To get those to work, LXDE needs elogind, libpam-elogind and policykit as well.
They hard coded systemd/elogind code into their full shutdown gui.

Added: If you want to keep antiX-22 free from systemd/elogind (as it is by default), you can use consolekit and its components and edit the menu to use the antiX shutdown gui.

Option 1 – systemd/elogind free

sudo apt update && sudo apt install lxde consolekit libpam-ck-connector

Then edit ~/.config/lxpanel/LXDE/config so logout reads like this

logout=desktop-session-exit

Reboot.

Option 2 – uses ‘standard’ lxde logout

sudo apt update && sudo apt install lxde elogind libpam-elogind

Reboot

Philosophers have interpreted the world in many ways; the point is to change it.

antiX with runit - leaner and meaner.

Thank you, Your ‘fix’ #2 corrects the problem. The first (preferred) option didn’t but I’m not sure it wasn’t my fault; I’ll know when I reinstall Antix-22 on my test system.

Thanks again,
