Keep the x11-input.fdi section from the Handbook, and also add the
following line to /etc/X11/xorg.conf, at the end of the "ServerLayout"

Option  "DontZap"  "false"

Restart your system, it should work now. (Just tried it on mine. It
won't work without both of these changes). Please report back if it
works for you!

By the way Xorg configuration becomes more and more elusive. Initially,
DontZap was enough. Then it had no effect at all and the fdi file was
needed. Now seems both are needed. What's next?

I'll test this in a few other systems and update the Handbook section
if  it seems to be the latest norm. Thanks!
