I tried this myself a while back and noticed the same thing: something
resets X server DPMS settings after the xset command has executed. Has
any Ubuntu representative considered the possibility that this bug may
cause burn-in-problems for displays over a longer period ? Not to
mention the obvious power waste.

I will be applying your delayed xset work-around script, thanks for that
idea.
