Weird issues after logging out and logging back in via LXQt logout

Support and Help

Hi everyone,

I’m facing a strange issue on Lubuntu. Whenever I log out of the system and log back in, several things stop working properly. Specifically:

  • waybar, swaync, and copyq don’t start/work.
  • When I press the power button, the logout/shutdown menu that should pop up doesn’t appear.
  • A few other minor things are also broken.

Here’s the weird part — this issue only occurs when I log out using the LXQt logout button and then log back in. It does NOT happen in any of the following scenarios:

  1. If the system was fully shut down and I do a fresh boot — everything works fine.
  2. If I reboot the system — everything works fine.
  3. If I log out using the command pkill -u $USER instead of the LXQt logout button — everything works fine.

So I’m really confused as to why logging out via the LXQt logout button causes these problems, while logging out via pkill -u $USER does not.

Also, it’s worth mentioning that this issue only happens on Lubuntu. I have the exact same desktop environment and setup on Arch Linux, and I’ve never encountered this problem there at all.

Any help or insights would be greatly appreciated. Thanks!

Providing release details would help us to help you.

Software versions change over time, when we know your release, we have [easy] methods to look up version details for the defaults for that release.

You posted (if I recall correctly) recent screenshots of a Lubuntu system running labwc which included a screenshot of a fastfetch type details; but we don’t know if you’ve got only one machine, or like me have multiple (running different OS/versions).

It sounds like some processes from your user session remain running after logout. Create another user, logout, login as another user and check if anything is still running.

Hi guiverc,

Thanks for your response. Here are the details:

  • I’m using Lubuntu 26.04 LTS
  • The issue only appears on this Lubuntu installation
  • I have only one machine

Hope this helps. Thanks!

Hi avb66,

I created a new user and tested as you suggested. Here’s what I did:

  1. Logged out from my original user (ali) via the LXQt logout button
  2. Logged in as the new user (linuxfixes)
  3. Ran the command ps aux | grep ali

Here are the results:
