GNOME Bugzilla – Bug 660434
Brightness reverted back to incorrect level after returning from idle
Last modified: 2011-10-07 09:49:46 UTC
Steps to reproduce the problem 1. Start gnome-settings-daemon with a relatively high screen brightness and "Dim screen to save power" enabled 2. Allow screen to go idle and dim/restore at least once 3. Disable "Dim screen to save power" 4. Change brightness to a lower setting 5. Wait about 30 seconds and move the mouse, the original high screen brightness will return I think the problem may be caused (indirectly) by http://git.gnome.org/browse/gnome-settings-daemon/commit/plugins/power/gsd-power-manager.c?id=67785fa2b1043bd5397669f92abbd210dbf23f24 - with "manager->priv->pre_dim_brightness" not being set to -1 after resetting the backlight. The problem does not occur if gsd is started with "Dim screen to save power" disabled.
I've pushed this to master: commit 51ba98ff6346007d252b2450ed4c1a479c41fb19 Author: Richard Hughes <richard@hughsie.com> Date: Thu Sep 29 14:32:17 2011 +0100 power: Do not revert to the pre-idle brightness if idle dimming is disabled We want to set manager->priv->pre_dim_brightness = -1 to indicate that we're restored the value and that no further restoration is required, as the user may have already altered the level. This will only happen if you disable dimming at runtime after having dimmed at least once. Resolves https://bugzilla.gnome.org/show_bug.cgi?id=660434 Can you test with that commit picked into a branch based on gnome-3-2 please, and if that works then I'll push to 3-2. Thanks.

Given the various screen brightness fixes applied since gsd 3.2.0 was tagged and released, when can we see a 3.2.1 release? From $ git log GNOME_SETTINGS_DAEMON_3_2_0..HEAD ./gsd-power-manager.c it looks like most of the problems I'm experiencing on Fedora 16 are already fixed in Git (see the duplicate bug 661108)
