Summary

This is tightly related to (T10537) #193

With GDM as login manager, if you don't login right away after boot, after a certain amount of inactivity, computer suspends automatically, regardless of users energy/suspend settings. For GDM, these settings can be changed via gesettings run as gdm user: su - gdm -s /bin/sh dbus-launch --exit-with-session gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'nothing' or via the config file in /etc/dconf/db/gdm.d/ as described in the above mentioned issue.

My personal stance is that auto-suspend-on-inactivity should be deactivated per default in GDM, at least if you are on ac. I understand the value of auto-suspend if you run on battery, but given that there are users for who wakeup after suspend does not work properly, for instance graphics not initalizing correctly, I would rather deactivate this. You can still trigger suspend manually in GDM, and I think suspend is also still triggered if you close lid.

Steps to reproduce

boot computer on login-screen (GDM), don't login right away, wait like 6 min

Expected result

suspend should not be triggered

Actual result

suspend is triggered

Just to give a further explanation why I think current GDM behaviour is no good: I think for example of my parents, 70 and 80 years old. Scenario is the following: They start computer, then, while it's booting, they decide to go make a tea, or to check washing machine, or whatever, and then, when they return after a short while, before they even had the chance to login, computer is already in suspend and they don't understand whats going on.

I agree, I can change the default in https://github.com/getsolus/gnome-desktop-branding when we land GNOME 46.

That would be much appreciated.

On a related note I'd like to mention that regardless of suspend beeing turned off for GDM with su - gdm -s /bin/sh dbus-launch --exit-with-session gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'nothing' GDM screen will go blank after some time. If screen blanking in GDM is undesired, this can be changed with su - gdm -s /bin/sh dbus-launch --exit-with-session gsettings set org.gnome.desktop.session idle-delay '0'
