"ps 5559" will tell you if it's running. Or "xdpyinfo -display :1".

You can start Xvfb at boot. Environment variables are per-process; it
doesn't make sense to try to set them outside of the cron scripts.
Also, you should either use "nolisten -tcp" and set the permissions on
/tmp/.X11-unix/X1 so that it is only accessible to the account under
which the cron scripts will be run, or use -auth.
