Can't get Intel 82915G on-board graphics controller to deactivate the monitor.
My computer has on-board video which `lspci -v` reports as follows:
0000:00:02.1 Display controller: Intel Corp. 82915G Express Chipset Family
Graphics Controller (rev 04)
Subsystem: Asustek Computer, Inc.: Unknown device 2582
Flags: bus master, fast devsel, latency 0
Memory at cfe00000 (32-bit, non-prefetchable) [size=512K]
Capabilities: [d0] Power Management version 2
I tried using the i810 driver but couldn't get it to work ("No screens
found" etc.). Using the vesa driver everything works fine *except* that
the screen won't go blank when the computer is inactive. (I know the
monitor is capable of handling this, since it used to do it correctly with
a different computer and RedHat.)
My XF86Config-4 file currently contains the following stanzas.
Identifier "Generic Video Card"
Option "DPMS" "on"
I would especially appreciate any suggestions for getting this graphics card
with the vesa driver to drop the monitor signal after a period of
inactivity. Alternatively, I'd be interested in debugging advice for
getting the i810 driver to work (it's supposed to be the correct one).
