Games :: LXDoom fullscreen?

Frugal install of DSL 2.0 w/ persistant /home and /opt. Installed the lxdoom extension however the config file only has entries for window size... How do I edit it to become fullscreen?

I Need to know this to so if you figure out let me know please

in the terminal type

beaver ~/.lxdoom/boom.cfg &

change the screen_width and screen_height settings and save before restarting doom.

.lxdoom is a hidden folder in /home/dsl and boom.cfg is the setting file.
