I,ve been having this problem too. From reading around the arch forum an others this is the problem.
I’ve installed xscreensaver to be able to stop my screen from turning off while watching tv in mythtv because of this.
Could not find bluetooth module; is the cinnamon-control-center package installed?
Loading Power module
/usr/bin/python2: symbol lookup error: /usr/lib/cinnamon-control-center-1/panels/libpower.so: undefined symbol: up\_client\_get\_can\_hibernate
the libpower is newer in arch than mint an the only way this will be fixed is when mint (ubuntu) moves to gtk 3.12 instead of 3.10.
Arch might lose cinnamon soon because of developement being so far behind. cinnamon in arch is at version 2.28 mint 17 rc is at 2.2.13 it will need some patching to be upgradeable. It can’t even be build for the aur either, thats broken too.
