This is needed by most window managers. Desktop environments
usually launch dbus-launch if a session hasn't been started yet
so this shouldn't hurt. The worst it can happen is that one
dbus session will be unused in case it's started twice.
The GDM change is backported from recent gdm.
With this patch, systemd-inhibit outputs a descriptive message when
desktopManagerHandlesLidAndPower=true (the default).
Before the patch:
$ systemd-inhibit
Who: /nix/store/[...]-xsession [...] (UID 1000/cassou, PID 18561/systemd-inhibit)
What: handle-power-key:handle-lid-switch
Why: Unknown reason
Mode: block
After the patch:
$ systemd-inhibit
Who: /nix/store/[...]-xsession [...] (UID 1000/cassou, PID 18561/systemd-inhibit)
What: handle-power-key:handle-lid-switch
Why: See NixOS configuration option 'services.xserver.displayManager.desktopManagerHandlesLidAndPower' for more information.
Mode: block
This was lost back in
ffedee6ed5. Getting this to work is
slightly tricky because ssh-agent runs as a user unit, and so doesn't
know the user's $DISPLAY.
Any reasonably new version of fontconfig does search that path by default,
and setting this globally causes problems, as 2.10 and 2.11 need
incompatible configs.
Tested: slim+xfce desktop, chrootenv-ed steam.
I have no idea why we were setting the global variable;
e.g., neither Fedora nor Ubuntu does that.
Option defaults should not refer to store paths, because they cause
the manual to be rebuilt gratuitously. It's especially bad to refer to
a highly variable path like a computed configuration file.
Should bring most of the examples into a better consistency regarding
syntactic representation in the manual.
Thanks to @devhell for reporting.

This has some advantages:
* You get ssh-agent regardless of how you logged in. Previously it was
only started for X11 sessions.
* All sessions of a user share the same agent. So if you added a key
on tty1, it will also be available on tty2.
* Systemd will restart ssh-agent if it dies.
* $SSH_AUTH_SOCK now points to the /run/user/<uid> directory, which is
more secure than /tmp.
For bonus points, we should patch ssh-agent to support socket-based
activation...
