[SOLVED] Brightness setting not restored

Brightness is always restored to max at each boot or when the system wakes up from sleep. The slider on GNOME desktop seems to reflect the previous setting. Controlling brightness with the slider or keyboard keys work as expected.

Re: [SOLVED] Brightness setting not restored

Adding the kernel parameter acpi_backlight=vendor fixed the issue.
