Description Guil Barros 2009-04-29 19:44:30 UTC

Description of problem:
Backlight dims correctly (though i wish i could set how much) when machine is idle but does non return to original setting when not-idle.

Version-Release number of selected component (if applicable):
gnome-power-manager-2.26.0-2.fc11.i586

How reproducible:
Everytime

Steps to Reproduce:
1. let machine idle
2. watch g-p-m dim screen
3. twiddle mouse
4. watch g-p-m un-dim screen to some other setting
  
Actual results:
Dim feature is pointless as i have to manually fix brightness every time it kicks in.

Expected results:
Brightness should return to setting it was at before it got auto-dimmed by g-p-m

Comment 1 Bug Zapper 2009-06-09 14:49:03 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Comment 2 Andrew Hecox 2009-07-11 15:25:36 UTC

seeing similar behaviour here... Guil ... still experiencing?

Comment 3 Guil Barros 2009-07-12 21:11:06 UTC

Yes, still happens.

Comment 4 Richard Hughes 2009-08-20 12:42:23 UTC

Does installing the latest gnome-power-manager package in updates-testing (and then rebooting...) fix the problem?

Comment 5 Guil Barros 2009-08-20 14:25:33 UTC

Installed per your IRC instructions, no change. Sorry :(

Comment 7 Guil Barros 2009-08-20 15:11:37 UTC

After talking to Richard we noticed that dim/undim works correctly if I uncheck "Reduce backlight brightness" in Power Manager Preferences. The argument being that this forces the backlight to always return to a dim state. I suggested that an automated system should not override a human-set value outside of a state transition and he did not think that was an incorrect statement. We will work on this in a different ticket and close this one out as it is not in fact broken :)
