Public bug reported:
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 witht he 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 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 does not reach the UI.
