Green signal (DPMS) problem

Green signal (DPMS) problem

Post by Andrei Demekho » Fri, 15 Nov 1996 04:00:00



According to FAQ, DPMS support is included in kernel, so one should just
use "setterm" command with appropriate flag to enable switching a
"green" monitor off. I have put "setterm -powersave on" in my rc.M
script, and enabled power management mode in BIOS, but my monitor is not
switched off after any period of inactivity!

Please help me, thank you very much.

E-mail CC: would be appreciated

I took a little time to solve this problem, but it is solvable:
Take a look at the file /usr/src/linux/drivers/char/vesa_blank.c
You can tell the kernel what kind of signal to send to your video to
shut the monitor down. IT WORKS FINE ON MY BOX!

What FAQ are you talking about ? I've searched the /usr/src/linux source tree
but couldn't find any references to "dpms".

Under X there is a separate power_save option documented under
XF86Config.

1. Enabling Screen "Green" Features (VESA DPMS)

I would like to enable "green" power saving features for my monitors
under ODT5 (and ODT3) - Is this currently supported?

If so, how do you enable this for activation for the text and graphics
consoles (ie. replacement screen savers which can trigger the power down
modes instead of simply blanking the screen).

I am using VESA DPMS compliant video cards and monitors.
(eg. Diamond Stealth 64 VRAM card).

Thanks,
-Rob
