[O] Idle time issue

[Tomas Grigera]

Hi list,

I'm setting up clocking to track idle time with org-clock-idle-time.
It didn't work at first and it took me a while to figure out why.

I use Emacs under x11 and yesterday's git head (812d0a53).  Since I
had not installed x11idle, idle time tracking failed silently. x11idle
is mentioned in the manual, but it says "For X11, you *can* install a
utility program `x11idle.c'" (my emphasis on can). It seems however
that one *must* install x11idle, or idle time tracking will not work
under x11.

It seems to me that either the manual should say x11idle is mandatory,
or that the x11 user should be given a choice to use either x11idle or
emacs idle time.

What do you think?  I am prepared to try and send a patch either way.

Tomas
