Public bug reported: As the title says, on this laptop the brightness controls are NOT saved after reboot.
What is saved instead, is only the keyboard brightness. I have tested two distros, Ubuntu 18.04.2 LTS and 19.04, happens on both systems. But there is a difference On 19.04, "systemctl status systemd-backlight@:*intel_screen_backlight_*" shows: "Saved brightness 20 too low, increasing to 75" On 18.04.2 does not show anything rather than the service starting normally The laptop is a Dell XPS 15 9550, the screen backlight driver is the intel one. ** Affects: systemd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1833532 Title: systemd-backlight does not restore screen brightness after reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1833532/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
