Some other relevant quotes:
“For years, I used to run Debian sid (unstable) on all my personal machines.”
“Sometimes things broke. But it wasn’t a big deal, because I could always get in there and fix it fairly quickly, whatever it was.”
“I’ve googled this issue, and found all sorts of answers pointing to polkit, or dbus, or systemd-shim, or cgmanager, or lightdm, or XFCE, or… I found a bug report of this exact problem — Debian #760281, but it’s marked fixed, and nobody replied to my comment that I’m still seeing it.”
… doesn't sound like somebody “who forget the beginner's spirit to look for answers on forums [etc]”
