Since systemd has been adopted for a while now, we should switch to
using it for light-locker as well. So I disabled ConsoleKit/UPower
support in favor of using systemd with logind. This fixed many issues
for me, and made light-locker working again.
I followed the PKGBUILD of Arch's package in determining the right
configure flags. See: https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/light-locker
In line with the Nixpkgs manual.
A mechanical change, done with this command:
find pkgs -name "*.nix" | \
while read f; do \
sed -e 's/description\s*=\s*"\([a-z]\)/description = "\u\1/' -i "$f"; \
done
I manually skipped some:
* Descriptions starting with an abbreviation, a user name or package name
* Frequently generated expressions (haskell-packages.nix)
