Xfce Power Management Problem in Sketch

["Stephen P. Molnar" <s.molnar@sbcglobal.net>]

I have just upgraded by Linux platform to v-9.0.0 from v-8.8.0.

Xfce Power Management fails to blank the display.

I have not been able to find a solution and would appreciate some 
assistance.

Thanks in advance.
