Title:
Brightness slider does not respond to brightness changes
Status in “gnome-control-center” package in Ubuntu:
Confirmed
Bug description:
The slider in the "Brightness and Lock" settings panel does not
respond to brightness changes by keyboard hotkeys.
Steps to reproduce:
1) Open "Brightness and Lock" from the control center
2) Change the brightness with the keyboard hotkeys
3) See that the brightness slider does not change
I read the similar (fixed) bug #893851 and I saw the attached patch
that updated the DBus interface. Now it seems the signal is not
reaching the UI for some other reason. If I run "dbus-monitor
type=signal" and set the brightness up and down with the keyboard, the
following output shows:
signal sender=:1.9 -> dest=org.gnome.SettingsDaemon serial=289
path=/org/gnome/SettingsDaemon/Power;
interface=org.gnome.SettingsDaemon.Power.Screen; member=Changed
signal sender=:1.9 -> dest=org.gnome.SettingsDaemon serial=295
path=/org/gnome/SettingsDaemon/Power;
interface=org.gnome.SettingsDaemon.Power.Screen; member=Changed
This seems to imply the signals are issued but they don't reach the
UI.
