This is quite simple.
You have to send in the geometry to the GTK application so that is self
can decide its geometry.
You don't need any window manager.
I run a lot of FreeBSD computers this way.
In rc.local you run something like
/usr/sbin/ntpdate -s 0.ubuntu.pool.ntp.org
/usr/local/bin/X -ac &
# Let the x-server have time to start
# Connect from any IP
/usr/local/bin/xhost + &
# Remove the cursor from the screen, turn off screensaver
/usr/local/bin/unclutter -root -idle 1 &
/usr/local/bin/xset -dpms &
/usr/local/bin/xset s off &
# set background
/usr/local/bin/xsetroot -solid Grey &
# show local time
# Startscript for infotable at LEV
DISPLAY=192.168.37.88:0.0 ./draw-text -x 0 -y 0 -X 896 -Y 307 -g logo -L "" -f 100 &
Note that the gtk-widget have to "resize" itself. So you must program it to
read its own "geometry". x , y , X Y (and some other stuff).
