Since Gnome 3.20, gnome-control-center requires xf86-input-libinput for properly managing input devices. Please keyword this package and re-keyword gnome-control-center.
And gnome-light.
Make modemmanager optional, if possible.
Moving sparc to CC instead of assignee so the new tooling actually sees it; updating package list to current control center version. sparc@: Feel free to opt out or de-keyword even more of course (otherwise you might have stuff that's not user friendly to configure if not re-doing gnome-control-center)...
hmm, or actually on Feb 4th various other sparc keywords were dropped for gnome-light, gnome-shell, gdm and gnome-tweak-tool with a reference to this bug. So I assume the intention was to de-keyword things to lighten the stable tree of sparc now, so closing this bug as WONTFIX.
