Quick question...

Is GDM the default/standard graphical login in linux distros? If so, I think that this could be good:

Morning Marc-Andre

GDM is the standard for gnome. Kde has its own called KDM.

I played with the utmp stuff, and it records the shells only, not the interactive sessions...

Any method other than the ps trick? (which may break of process names changes...)

Working on that... it looks simple, but the code isn't giving me what I expected...
/me grumbles looking at unknown APIs...

Maybe more interesting than "nobody logged on" would be "system load
very low", e.g. "load <= 0.1*(number of cores)", possibly combined
with "free memory + memory used for cache >= threshold".

Nah:

      #include <utmpx.h>

      struct utmpx *getutxent(void);
      struct utmpx *getutxid(const struct utmpx *);
      struct utmpx *getutxline(const struct utmpx *);
      struct utmpx *pututxline(const struct utmpx *);
      void setutxent(void);
      void endutxent(void);

is the POSIX/SUS interface to do that. Or just run "/usr/bin/who -q"
:)
