No, no,  no! I installed  a new menu  item “Power management”  in my
“right-click-desktop-menu” with  two new entries “Screen  always on”
and “Screen to sleep when idle” which execute

# Screen to sleep when idle
gsettings set \
	org.gnome.settings-daemon.plugins.power sleep-display-battery 600 &&
gsettings set \
	org.gnome.settings-daemon.plugins.power sleep-display-ac 600

# Screen always on
gsettings set \
	org.gnome.settings-daemon.plugins.power sleep-display-battery 0 &&
gsettings set \
	org.gnome.settings-daemon.plugins.power sleep-display-ac 0

But  this  fails.  When  I  get  this  to  work,  I  will  create  a
dedicated desktop that  executes these commands when  the desktop is
displayed and switches back to display sleep when another desktop is
displayed.  That way  I don't  need  an applet  or to  click on  any
button, I  simply move  my application  (vlc, terminal  window,…) to
that desktop. That's my understanding of “easy”.

It seems to be a bug in Gnome:
