Description of problem:
xscreensaver does not power off my monitor correctly. A few minutes after the
monitor is powered off. My monitor wake up and reports
"The Monitor is in power save mode, activate by using PC".
Between the time the stand by mode starts and the time suspend mode starts, my
monitor reports
"Monitor is working out of scan range, change PC setting."

Version-Release number of selected component (if applicable):

How reproducible:
very high on my own machine. (IBM Aptiva 964, PIII 667, Dell P780 Monitor)

Steps to Reproduce:
1.In xscreensaver preference, set blank after 5 mins, cycle after 10 mins.
2.In xscreensvaer preference, set stand by, suspend after, and power off after
to 1, 2, 3 mins.

Actual results:
As above.

Expected results:
Should be powered off and not wake up unexpectedly.

I believe xscreensaver just ties into the standard X dpms code.

Attach your X server config and log file.

Also, disable APM at startup, and in your BIOS, and try running X and testing this
again.  If disabling APM makes the problem go away, then it's most likely
a BIOS bug in APM power management handling.
