Description Kevin DeKorte 2009-04-06 10:04:48 EDT
Description of problem:
gnome-screensaver will not turn off the backlight on displays when after the correct time period. The GDM screensaver does work correctly

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Set screensaver to 10mins
2. Set "turn display off in gnome-power-manager" to 10 mins
Actual results:
screen goes blank (screensaver is using the blank option)
but backlight never goes out

Expected results:
backlight should go out on displays (I have two)

Additional info:
radeon driver but using nomodeset
Comment 1 Tom Horsley 2009-04-06 13:40:54 EDT
I think I've observed this same behavior with the nouveau driver. The screen
will go black, but the signal does not shut off completely (doesn't matter
much since my monitor doesn't actually respond to DPMS, but I see a box
that says "no signal" in fedora 10, and just get a blank screen in
fedora 11).
Comment 2 Kevin DeKorte 2009-04-06 13:56:58 EDT
If I run "xset dpms force suspend" my displays will power off as expected and come back on when I move the mouse.

Thinking this bug might be related to gnome-power-manager as well. Gonna add rhughes to it. If it is not related he can drop off.
Comment 3 Adam Williamson 2009-04-06 17:06:40 EDT
I believe this is a known issue - someone mentioned it to me in the context of a recent graphics card test day, and suggested changing the DPMS test case from g-p-m to xset - but I can't find another report for it in Bugzilla, so it may not have been reported otherwise yet. Assigning.

I'm having the same issue. The screensaver will activate, but my monitor never powers off. If needed, the lspci output for my video card is attached.

*** This is a duplicate of bug 485601. The latest svn version of g-p-m fixes this issue. ***

ah, thanks - I never managed to hit the magic phrase "display sleep" in my searches :\
