I need more testing on this, but this could definitely bite us :/

Ok, thanks, I'll check on that.

Yeah, this is the same stuff as just above.

Please don't. It's _really_ messy. Thunar needs a correctly setup
consolekit, xfce4-session too. For most Xfce users this will be
documented in xfce4-utils:README.Debian and/or xfce4:README.Debian. And
this is the bug where we discuss it. Not the other ones, please.

Yeah and we definitely won't advertise them :) We'll recommend one way
for console users (and the display manager stuff), and other users will
do their stuff based on that.

Yeah, it's been quite some time since I first though of putting all
startxfce4 stuff into /etc/X11/Xsession.d and only keep a stub. But I
don't really want to divert too much from upstream and other distros.
