Hey folks,
for a couple of days now I have a strange issue. Every time I leave home (or do something else for a while) I turn off the TV. When I turn on the TV my Arch installation suspends to RAM. I tested it today and it is time independent meaning as soon as the TV is I turned on no matter how long it was turned off the computer activates the suspend procedure. I deactivated the complete Power Management in KDE system settings which doesn't solve the problem. I tried using Cinnamon and this makes it even more strange. As soon as I log into Cinnamon from lightdm the computer goes into suspend to RAM is is immediately activated again ...
Computer information:
Notebook: Lenovo T420, using a docking station
OS: up to date Arch Linux
GUI: KDE Plasma
Display Manager: lightdm
Monitor: Sony KDL-55W805b TV, connected to DVI port on docking station because I had troubles with HDMI
As far as I can tell the systemd log does not contain any of interest but added it anyway. I started with the last log entries before the issue occurs today at night and stop as soon as the last "suspend" entry is finished in the log.
