Vincent, is it at all possible for you to test Ubuntu GNOME 17.04 before
and after this proposed fix? I don't have the hardware to verify your
fix and the Ubuntu Stable Release Update team really likes for bugfixes
to be verified.

I am closing the 'linux' portion of this bug because this apparently can
be fixed in gnome-settings-daemon and unity-settings-daemon.

Please try USD here: http://people.canonical.com/~khfeng/lp1683445/
I'll send a patch to GSD/USD. It may take some time to backport it to
17.04 though.

Hi,
Glad that it helps :).
I am not sure if the interface actually doesn't work, because it might if the
Optimus mode would switch to use the Nvidia card dedicatedly, but since that is
not supported by the nouveau driver, it might not happen. Not sure what
happened to the Bumblebee projects
Okay, didn't know the "enabled" part. Originally I was thinking get the
value from vgaswitheroo - but "enabled" here will do.
Though I still think nouveau shouldn't expose a backlight interface
under /sys with no function at all.
I'll work on GSD/USD as an alternative.

Hi,
Thanks for your feedback. I had a chat with somebody with some experience and
he suggested it should be fixed in userspace, here:

This is what he suggests (if the above is indeed what Ubuntu uses,

You received this bug notification because you are a
nvidia_backlight.c thinks the graphics chip is connected to LVDS, hence
create a backlight interface, 'nv_backlight'.
This can be somehow 'workaround' in userspace tool, but I think it's not
the best way to do it - the backlight interface shouldn't be there if
it's not working at all.
I'll file
Verified with Kubuntu / Gnome Ubuntu 17.04 LiveUSB, brightness

E6430 brightness
The brightness hotkey will change the "brightness" level from
/sys/class/backlight/nv_backlight/, but it seems that it's actually
using the Intel one.
Modify the "brightness" file in /sys/class/backlight/intel_backlight/
can change the screen brightness.

This issue can be reproduced on another E6430 here, with the same A18
BIOS / 4.10.0-19 kernel. (But the interesting thing is that it cannot be
reproduced with its variant, E6430ATG, even if they're all I+N config,
and using the same BIOS)
Some debug info with the 4.11rc7 mainline kernel
Hi Joseph,
Thank you for the quick response.
I tested this with the intel-drm-next kernel and the one you suggested and get
the exact same behavior. It seems like a regression, because this was not
needed on 16.04/16.10.
I marked it as confirmed and added the tag, thanks you.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.11 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

sudo vim /etc/default/grub
