Not sure if it will help anyone else, but for me this is fixed after I edit my /etc/default/grub file so that the GRUB_CMDLINE_LINUX_DEFAULT line looks like the following (and also running update-grub plus rebooting afterward):
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor" My laptop now keeps its brightness settings properly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/870805 Title: Screen dialog won't remember brightness setting To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/870805/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
