In my case (XFCE), it's as simple as cracking open the "Window Manager
Tweaks" control panel and hitting the "Enable display compositing"
checkbox. I assure you, this is far easier for your customers than the
old method of enabling BackingStores and SaveUnders (which involved
editing configuration files by hand, then restarting the X server -
without which your 'merely sets a bit' would be ignored). I believe
GNOME and KDE have an equivalent setting, enabled by default on many

To be fair, you may have customers still using CDE or OpenLook. But
those same customers are likely still using a SaveUnders capable X
server too.
