Hi all,
ii systemd 237-3ubuntu10.3 amd64 system and
service manager
ii systemd-sysv 237-3ubuntu10.3 amd64 system
and service manager - SysV links
running on a 64bit Linux Mint 19 (based on Ubuntu Bionic) Dell Latitude
laptop.
Either NetworkManager or systemd is suspending the system after it is
powered up when the laptop is docked with the lid closed. This does not
happen when the laptop is used without the docking station (and lid open).

This also did not happen with the previous version of Linux Mint 18
(based on Ubuntu Xenial).

I suspect systemd is initiating the suspend but it's not clear from the
logs. Is there a way to increase systemd's verbosity? Any suggestions
how to fix this small but rather (daily) annoying problem? The system
should obviously not suspend itself when it's used with a docking
station and external monitors. The lid needs to stay closed so the
system uses the external monitors and not the laptop screen.
regards,
Jan
