Description Walter Neumann 2007-11-24 17:16:42 UTC
Description of problem: Since installing fedora 8 screen blanking on my laptop
does not work, whatever settings I use in pm-utils preferences. If I set
blanking manually from a terminal using "xset dpms 0 0 300", after a few seconds
dpms has been reset to 0 0 0.  Killing gnome-power-manager fixes the problem, at
the cost of losing the rest of its functionality.


Version-Release number of selected component (if applicable):
pm-utils-0.99.4-6.fc8

How reproducible: Unavoidable: My screen never blanks, whatever I do.


Steps to Reproduce:
1.Do "xset dpms 0 0 300" from a terminal. "xset -q" shows these settings.
2.After a few seconds do "xset -q" again and settings are changed to 0 0 0
3.
  
Actual results:
Screen never blanks, even if blanking is set im pm-util preferences or in
gnome-screensaver. Trying to set blanking manually as above is thwarted by
pm-utils.  

Expected results:
Screen should blank when machine is idle

Additional info:

I have uninstalled gnome-screensaver to be sure the problem is not related to
that. After killing gnome-power-manager I can set blanking with "xset dpms 0 0
300" and it works fine.

When killing gnome-power-manager helps, I believe it is a problem of this
package and not pm-utils. If you have any information on how pm-utils is
involved (which I do not think, because it only runs when you
suspend/hibernate/resume/thaw) then please reassign this bug to pm-utils.

Comment 2 Richard Hughes 2008-09-17 10:14:37 UTC
Right, g-p-m controls the blanking in the active session, as xset does not have inhibit controls or even a notion of multiple sessions active on one machine. Why do you want to use xset? Doesn't the screen blanking in g-p-m work for you?

Comment 3 Walter Neumann 2008-09-17 12:58:08 UTC
It is working fine for me at the moment in Fedora 9 so I'm marking it NOTABUG.

In Fedora 8 g-p-m screen blanking would blank the screen without turning off the backlight (on two different laptops and my workstation).
