Public bug reported:
Note: I'm flagging this as a bug in gnome-settings-daemon, but the
program itself is not buggy. It's rather the usage of this program
instead of unity-settings-daemon in ubuntu 17.10 that causes a system
regression.
---
Up to and including Ubuntu 17.04, unity-settings-daemon was used to managed
suspend policy in the default graphic session (Unity). Unity-settings-daemon is
a fork of (an old version of) gnome-settings-daemon.
Now that gnome-shell is the default environment, session management is handled
by gnome-settings-daemon. In particular, the action to perform when the lid is
closed is handled by the gsd-power plugin of gnome-settings-daemon (as it was
by unity-settings-daemon).
With unity-settings-daemon, two dconf keys where honored (lid-close-ac-
action and lid-close-battery-action, under org/gnome/settings-
daemon/power ) to specify what action are performed when the user closes
the laptop lid, depending on whether the laptop is plugged or on
battery.
In Ubuntu 17.10, gnome-settings-daemon ignore those settings (unless
their value is 'ignore') and delegate actions to systemd-logind. The
latter has no knowledge on whether the laptop is plugged or not and
apply the same action regardless.
This is a regression in a useful (and I believe popular) functionality.
It is common to want the laptop to suspend when unplugged but expecting
it to remain running when plugged (I believe this is the default on
MacOS and windows and both system can be configured to distinguish
between on-AC and on-Battery).
The functionality can be restored with a bit of sweat with either hooks
for acpid (or maybe a session script using the gnome framework to detect
events and apply the correct policy, acpid-scripts run as root), but
this is clearly not something the average user should have to tinker
with.
At the *very least* release note should advertise this regression (as a new
feature ?) but ideally provide a compatibility layer to restore this
functionality.
