Thank you, but I wanted to make the systemd-logind path work instead of the sudo magic which I find kinda hackish. I think my system meets the requirements, although I am not so sure when 'it should work' is mentioned in various places, whether it is supposed there are (for example) some polkit rules present in the system (of which I didn't find any on my gentoo box). The wiki link you mentioned does lead to some more information about the permission checking which I'll investigate when I have more time. But otherwise, short of installing Arch somewhere and have a look if there's anything present that could make this work I am clueless :( Cheers, Lukas
