Using "acpi_backlight=vendor" and also creating the "80-backlight.conf" file with the contents shown on that page, results in the brightness keys still doing nothing, and the gnome brightness slider not working.
The /sys/class/backlight/intel_backlight/brightness file still works fine though.
I think that's everything in the workaround section there. But let me know if there's anything else I need to check or anything.
