Ubuntu has problems with power saving (muti-display)

Using Ubuntu 8.04.1 (up to date)
I have a dual monitor setup, and I recently switched from “Separate X-Sessions” to a “TwinView” and now my monitors won’t go into standby/sleep (power saving) state. I’ve tried changing the settings in System>Power Management>Display> “Put display to sleep when inactive for” but no matter what I set it to (for a time limit) it NEVER goes into sleep mode. I’ve left the computer on for hours on end, and they never go into sleep. But when I switch from “TwinView” to “Separate X-Screens” the monitors go to sleep right on time, EVERYTIME.

p.s. I am NOT using Compiz (don’t know if that makes a difference or not).
System>Preferences>Appearance>Visual Effects = NONE.

Hopefully this will be fixed soon…
