The gnome-power-manager is unable to turn off the backlight of my laptop's screen. The screen only gets blanked but the backlight remains at full brightness on. Even trying to do it manually with "xset dpms force off" only blanks the screen. To actually be able to turn off the backlight I have to use "vbetool dpms off". Even setting in xorg.conf: Option "OffTime" "20" has no effect either. Reproducible: Always Steps to Reproduce: 1. Set screensaver to a short time 2. Set "Put display to sleep when inactive" to a short time as well 3. Wait for the time to pass and see what happens Actual Results: Display gets blanked (backlight is on) Expected Results: Display should be turned off (backlight as well)

do you have gnome-screensaver installed ?
I have gnome-extra/gnome-screensaver-2.26.1 installed. What I actually noticed is that the screensaver is blanking my display and power manager does absolutely nothing for me. If I disable the screensaver the screen stays lit (doesn't get even blanked).
GPM is starting but is not detecting idle time from my experience so far. With all of the gnome-2.26 installed as what is in portage.
Downgrade to gnome-screensaver-2.24.* and gnome-power-manager-2.24.* will be able to put the monitor to sleep.
The versions to make power management work are: gnome-extra/gnome-power-manager-2.24.4-r2 gnome-extra/gnome-screensaver-2.24.1-r1 gnome-extra/gnome-screensaver-2.26.1 breaks the power management of gnome-power-manager making it so that the screen no longer turns off.
Take a look here, the blanking problem seems to be fixed - the issue was in Xorg and not in gnome-power-manager. There is a patch linked in the blog post below that should be applied to xorg-server-1.6.3. http://blogs.gnome.org/hughsie/2009/08/14/blanking-in-gnome-power-manager-fixed/
I've tested that patch and it seems to fix my random blanking problems. But I'm not sure this bug is the same thing. I'll open a new bug pointing to that patch.
new bug is #281698.
It seems that after I updated to the new gnome-power-manager 2.26.4 the problem is fixed for me. it now turns off the backlight.
The same doesn't happen here. Anyway, the developer says that he coded a couple workarounds, but the xorg patch is the right way to go. http://blogs.gnome.org/hughsie/2009/08/17/gnome-power-manager-and-blanking-removal-of-bodges/
that patch is in xorg-server-1.6.3.901, could you try it out ?
Issue fixed for me. Please feel free to reopen this bug if it's not for you. Thanks for reporting.
It seems that it doesn't really work still. It doesn't turn off the screen. It just remains blanked. I have xorg-server-1.6.3.901-r1 and it doesn't go to sleep/turn off.
Ignore my last post. It's working for me as well.
I'm using gnome stable but I suffer from the same problem. I tried to upgrade to gnome-power-manager-2.24.4-r2 but this doesn't solve the problem. I tried either to set /apps/gnome-power-manager/backlight/dpms_method_ac and /apps/gnome-power-manager/backlight/dpms_method_battery to "off" (instead of the "default" default one). Sometimes it seems to work, other times doesn't. I currently use the xorg-server-1.6.5 amd64 arch here. If you need more details, just ask.

(In reply to comment #17) > I've tried to downgrade to xorg-server-1.6.3.901-r2 but it didn't help 1.6.5 is the only version that has all the patches for g-p-m to work properly. Now you're probably having a g-p-m bug. Please file a new bug report, let's keep this one closed. Thanks
