We have a problem with LTSP 5 in Debian Buster: some user processes keep
running even after a user logs out:

Here's an example for the user "vma":

The problem seems to be related to these issues:

https://github.com/mate-desktop/mate-session-manager/issues/165 (we use
XFCE)

https://github.com/canonical/lightdm/issues/45

https://github.com/systemd/systemd/issues/8598 (not sure about this one)

Is there a quick workaround? Maybe an LTSP script that will kill these
processes when a user does logout?

Regards,

Vladimir.
