gnome - disable auto brightness on login

Hello,

When I log in using gnome the brightness of the monitor is automatically adjusted to 100%. Is there an option to disable this so the brightness can stay as it was configured?

Re: gnome - disable auto brightness on login

Hi, I cannot explain why GNOME wouldn't honor your settings, I'm assuming you used the slider or gnome-control center > power settings. As a workaround you can use D-Bus to control desired brightness level at login. That wiki page only mentions the 'set' command:

gdbus call --session --dest org.gnome.SettingsDaemon.Power --object-path /org/gnome/SettingsDaemon/Power --method org.freedesktop.DBus.Properties.Set org.gnome.SettingsDaemon.Power.Screen Brightness "<int32 50>"

Use the below to 'get' the current level:

gdbus call --session --dest org.gnome.SettingsDaemon.Power --object-path /org/gnome/SettingsDaemon/Power --method org.freedesktop.DBus.Properties.Get org.gnome.SettingsDaemon.Power.Screen Brightness
