Oops, it was either acpi_osi=! or acpi_osi='Windows 2009' that was
causing the problem. I had copied them in to try and get the nvidia card
working after resume, but it turns out they aren't needed for the nvidia
card to work anyway.
Sorry for the noise.

Title:
Screen backlight control does not work in Disco on Dell XPS 9560
Status in linux package in Ubuntu:
Invalid
Status in upower package in Ubuntu:
Invalid
Bug description:
When I press the screen backlight up/down buttons, gnome-shell pops up
the backlight control window saying that the backlight is being
adjusted, but the actual screen brightness does not change.
The problem is that gnome is adjusting
/sys/class/backlight/acpi_video0/brightness instead of
/sys/class/backlight/intel_backlight/brightness. If I manually change
the latter as root with, say:
root@xps-9560:~ echo 600 >
/sys/class/backlight/intel_backlight/brightness
then the brightness changes.
The brightness control worked fine in Cosmic on this laptop, so this
is a regression.
