I try not to stand for begrudgingly doing anything, personally.

How terrible, the aim should be for independent parts that even work
with startx. I see freedesktop as less and less of a standard and the
website is a terrible amalgamation of stuff. 

I use sudo for all these things. I just create the
buttons/launchers/menu and sometimes use yad or gxmessage, scripts etc.
to do whatever I need. For suspend don't forget a double select or are
you sure message to prevent accidental clicks. On xfce you can use arrow
button position -> inside on a panel launcher. I haven't the time but
have considered doing a distro just to show how easy it is to do what
99% of users need, better and much more securely.

There was however a time when I tried to play ball and added


to sudoers which got suspend and hibernate back with the shipped
buttons. Not sure if that still works as I switched to fvwm and
actually prefer standard setups that work everywhere and with the bonus
of less code running as root

I used to use the mount plugin for xfce but now use gkrellm whose
config is far less annoying to port from system to system. I find *conf
systems trying to solve a non-existent problem and launchers without
names nauseating.

I use fvwm1 and everything works. I use it mainly because it ships with
OpenBSD and is audited and simple for anyone to use but because
everything works and it's so fast and simple to lock down that I love
it. fvwm2, xfce and freedesktop compliant desktop systems do
pre-populate your menu which most users would want and works well but I
actually find a menu with only what you want on, not to mention all
sorts of new functions using yad and gxmessage to actually be far more
useful once done, not to mention rock solid from upgrade to
upgrade/install and yet easily changed. It would also be quite easy to
create a script to dynamically create a menu if needed, though I would
lock it down and use it as required personally.
