It took me quite a while to get the power-saving blanking to work
under X. Here's what I did (for a Number Nine (S3-based) card).
I don't know if it is necessary, but it seemed to me that I had
to make 2 changes; one in the "Device" section and one in the
"Screen" section. I put both changes at the bottom of the sections.
Section "Device"
...
Option "power_saver"
EndSection
Section "Screen"
...
# ------------------------ power-saving stuff --------------------
# BlankTime time
# sets the inactivity timeout for the blanking phase
# of the screensaver. time is in minutes, and the
# default is 10. This is equivalent to the
# Xserver's `-s' flag, and the value can be changed
# at run-time with xset(1).
BlankTime 10
#
# SuspendTime time
# sets the inactivity timeout for the ``suspend''
# phase of the screensaver. time is in minutes, the
# default is 15, and it can be changed at run-time
# with xvidtune(1). This is only suitable for VESA
# DPMS compatible monitors, and is only supported
# currently by some Xservers. The "power_saver"
# Option must be set for this to be enabled.
SuspendTime 60
#
# OffTime time
# sets the inactivity timeout for the ``off'' phase
# of the screensaver. time is in minutes, the
# default is 30, and it can be changed at run-time
# with xvidtune(1). This is only suitable for VESA
# DPMS compatible monitors, and is only supported
# currently by some Xservers. The "power_saver"
# Option must be set for this to be enabled.
OffTime 120
# # Refer to /usr/X11R6/lib/doc/README.S3, and the XF86_S3 man page.
