Since the latest update of Gnome / GDM my computer seems to be put into suspend mode when I am idle on the logon screen for about 20 minutes.
This was not the case before the update.
Current Version of gnome-session & gdm
3.28.0. I'm running Arch Linux.
The system log, centered around
Mar 29 17:21:17 oliver-desktop kernel: PM: suspend exit +/- 200 lines. If you need more, let me know.
I have looked through a lot of the gsettings, none of the ones I tried were able to make gdm behave otherise. Also, the configuration documentation does not hint to any option related to auto-suspend.
