Hey Affinity, sorry to say it didn't workout. What you did instead was push me into another round of trial and error. Recalling Xvesa's cli options I went with what seemed logical, namely tossing in the v and s switches (screensaver blanking and timeout in minutes respectively). To note, these settings waitforX and wouldn't work placed in rc.local.
Xvesa -br -screen 1024x768x32 v -s 2 -shadow -mouse /dev/input/mice,5 -nolisten tcp -I >/dev/null 2>&1 &
Thanks all the same.
