In /var/log/Xorg.0.log i found the following message that I don't understand and that sounds concerning to me:

[  4559.714] (II) seat-libseat: libseat integration requires -keeptty and -keeptty was not provided, disabling libseat integration

Do I have to be concerned about the "disabling libseat integration" part?

Do I need seatd integration and if yes where should this "-keeptty" parameter go to enable the integration?

seatd is installed an running:

$ ps -ef|grep seat
root      2098     1  0 20:55 ?        00:00:00 /usr/sbin/seatd -g video

A web search about this message didn't come up with anything useful.
