I still don't understand how all the parts of GNOME fit together, so I
can't give a full review of these patches.

But, with these patches, I can successfully prevent my laptop from
sleeping when the lid is closed. Thank you!

Looks okay, but as I said before, I'm no expert on this stuff.

Can you add some comments explaining this patch (and a link to the source, if
applicable)?

Please specify which section of gnu-system.am the file is being added
to. In this case, it's dist_patch_DATA. See the commit log for the exact
format.

How about setting these variables in #:make-flags instead of replacing
the install phase? Would that work?

Oof, do we really have to propagate python-2 (and the others)?

Can you paraphrase this? I don't think the synopsis should be the same
as the package name. How about something like this: "GNOME advanced
settings control panel"?
