New DPMS behavior in 7.4

[Mark Kirkwood]

I've recently upgraded to Xorg 7.4 and Gnome 2.26. I notice that when
the monitor screen in blanked that the power lamp stays green always -
never goes to orange (it used to with Xorg 7.3 + Gnome 2.24). Is this
expected?

System is RELENG_7 from 2009-04-20 with Xorg 7.4 and Gnome 2.26 from ports.

Hardware is ASUS A8VX plus ATI 9600 PRO. I'm using the radeon driver
with an xrg.conf generated by X -configure. Hopefully relevant sections are:

Section "Module"
Load "extmod"
Load "record"
Load "dbe"
Load "glx"
Load "dri"
Load "dri2"
EndSection

Section "Monitor"
#DisplaySize 430 270 # mm
Identifier "Monitor0"
VendorName "HWP"
ModelName "HP L2045w"
HorizSync 24.0 - 93.0
VertRefresh 50.0 - 76.0
Option "DPMS"
EndSection

Section "Device"
Identifier "Card0"
Driver "radeon"
VendorName "ATI Technologies Inc"
BoardName "RV350 AP [Radeon 9600]"
BusID "PCI:1:0:0"
EndSection

Cheers

Mark

I don't know, but you can check the blanking and DPMS and times for
Standby, Suspend and Off with "xset -q", e.g.

# xset -q
...
Screen Saver:
prefer blanking: yes allow exposures: yes
timeout: 600 cycle: 600
...
DPMS (Energy Star):
Standby: 900 Suspend: 0 Off: 0
DPMS is Enabled
Monitor is On

This fits with what I explicitly configure in xorg.conf.

Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
Option "blank time" "10"
Option "standby time" "15"
Option "suspend time" "0"
Option "off time" "0"
Option "AllowEmptyInput" "off"
EndSection

Make sure you have the green_saver kernel module loaded.

# kldstat | fgrep green
32 1 0xc614f000 2000 green_saver.ko

If you don't, then add saver="green" to your rc.conf and "kldload
green_saver".

Thanks Andrew,

Adding similar lines into xorg.conf results in an encouraging entry in
X11.0.log:

(**) Option "BlankTime" "10"
(**) Option "StandbyTime" "15"
(**) Option "SuspendTime" "0"
(**) Option "OffTime" "30"

However xset does not pick 'em up:

DPMS (Energy Star):
Standby: 0 Suspend: 0 Off: 0

DPMS is Enabled
Monitor is On

... and sure enough, monitor light stays green, even after 30 minutes. I
have the 'green_saver' module loaded:

$ kldstat |grep green
7 1 0xc5cbf000 2000 green_saver.ko

Any ideas? Thanks

Mark

Looks like something which starts after the X server is applying
different settings. That something is very likely a desktop manager -
Gnome, KDE, XFCE, etc.

If you are running one of these, then look at the settings relating to
screensavers, power settings or wherever it hides these settings.
