apport information ** Tags added: apport-collected zesty
** Description changed: I am not sure if this is the right place to report this, so feel free to move it elsewhere. It looks like the systemd-backlight service (/lib/systemd/system /[email protected]) does not restore the brightness level (although it saves it before shut-down). However the following command does restore the saved brightness: sudo /lib/systemd/systemd-backlight load backlight:intel_backlight As a temporary solution to automate it at boot I am using the following line added to the root cron: @reboot /lib/systemd/systemd-backlight load backlight:intel_backlight - Ubuntu 4.10.0-20.22-generic 4.10.8 - Gnome 3.24 Please, let me know if you need more info.
