I would use lightdm but for some crazy reason, on both FreeBSD and Linux with my new video hardware, when coming out of a desktop or WM back into lightdm, my monitor goes into DPMS mode and this is unrecoverable. Not all distros with lightdm do this but some do. It might be light-locker, not sure, but regardless, it is not a workable solution. I have switched to lxdm and slock and it works perfectly. I can live with the wife not being able to shut down - she rarely uses my computer anyway.
I may play around with lightdm on Void to see if it works and if so, switch. Thanks for the help!
