["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Nicolas Devillers, from my personal experience, regarding backlight bugs
where one is forced to use acpi_backlight=vendor to enable it, these
reports typically result in upstream making a quirk for the hardware in
order to enable the backlight by default. Hence, the best strategy would
be to get the quirk merged upstream, in turn pulled downstream and
supported in Ubuntu, then refocus on how if the quirk still causes
suspend to not work, refocus to this.

Hence, could you please open a new report via a terminal:
ubuntu-bug linux

and feel free to subscribe me to it.
