Bug#839912: (no subject)

[Jean Baptiste Favre]

For the record, I've this exact problem on Asus Zenbook UX305LA.

As stated in [1] the issue seems to come from gnome-settings-daemon
trying to set backlight as root, which fails.

Log flood can be stopped with acpi_als blacklist adding

blacklist acpi_als

in /etc/modprobe.d/blacklist.conf

Cheers,
Jean Baptiste
