>+1. FWIW, example of xrandr:
Unfortunately I can't provide such a plain example, however apart from
irrelevant content in xorg.conf.d/ and some irrelevant customization
scripts, a dirty hacked scripted named xdh-feh calls another dirty
hacked script /usr/local/bin/xdh. I doubt in a hurry dirty written
scripts do help a lot, however, a script could work around issues that
GUIs using xrandr don't. I recommend to use Google (not another search
engine, because sometimes Google unfortunately still provides the best
hits on top), if the man page doesn't help.
