You need to install the 'rfkill' utility to control bluetooth.
The main problem with the current 'Samsung Tools' is that the system service uses absolute paths for the commands it needs, but some of these paths are different in archlinux (for instance, in ubuntu the 'lsmod' command line utility is located in /sbin/, in archlinux in /bin/).
Also, the 'laptop-mode' and 'kernel parameters' options don't work correctly in archlinux.
Anyway, everything will be fixed in the next version.
