hello, I put the helium repo and pass the debian to stretch, before I worked the brightness control with the FN in the update seems that there is some problem in some configuration.

Are you sure the update went through OK?
Can we please see the output of these commands:
uname -a
apt-cache policy
Please use code tags when posting the output.
If you are running the new kernel version then you may have to experiment with some parameters:

We don't recommend using the deb-multimedia repositories with BunsenLabs.
You can try the kernel parameters listed in my ArchWiki link by pressing "e" with the BunsenLabs menu entry selected in the GRUB (boot) menu then adding them (try just one at a time) to the end of the line that starts with "linux" — <Ctrl>+x will then boot the modified entry.
If you find that one of the parameters works the edit the file at /etc/default/grub and add it between the quotation marks after GRUB_CMDLINE_LINUX then save the file and use `sudo update-grub` to, erm, update GRUB.

The multimedia repository needs it for Flacon, a program to split the songs from a flac file.
It seems complicated to play the grub, I'll look, thank you.
Another detail I do not know if it is necessary to open another post, is that there are two energy icons, when tint2 is not configured so.

That is because the stretch version of xfce4-power-manager now allows for a systray icon so the fdpowermon package is no longer needed (this is what is producing the second icon).
Simply edit ~/.config/openbox/autostart and remove the "fdpowermon" line to stop this happening.
There have been several other changes to the autostart file that you may want to merge with your own version, here it is in full:

Thanks a lot for your time, the icon is already solved. I have to look at the brightness, so helium seems to work correctly.
A good job .

Hello, I have tried the four options of archwiki:
acpi_backlight = video
acpi_backlight = vendor
acpi_backlight = native
acpi_backlight = none
Adding the line to the grub:
GRUB_CMDLINE_LINUX = "option"
And then updating the grub:
sudo update-grub
Reboot to check the changes but it did not work for me.
when testing the options the brightness was to the maximum and leaving the grub as it was to say that it is in the middle but if able to regulate it.

Had the same issue with Devuan CROWZ openbox, upgraded from jessie to ascii 4.12 bpo and backlight functions either failed or not functioning properly. Not sure if this is an Intel issue only.
Installed backlight and created file /etc/udev/rules.d/81-backlight.rules
# Set backlight level to 8
SUBSYSTEM=="backlight", ACTION=="add", KERNEL=="acpi_video0", ATTR{brightness}="8"
Using a Dell 5050N - Intel. Fixed my issue and brightness back where it was before upgrade.
Hope this helps.
cheers

^ Thanks zephyr!
Not sure if this is an Intel issue only.
Good point.
@hathor, what is your hardware?
lspci -knn | grep -iA2 'vga\|3d'
Can we also see the output of:
find /sys/class/backlight
Also, have you tried the xbacklight package?

nvidia I do not have it installed, I'm using the intel.
I just tried backlight throw me this:
No outputs have backlight property
what I said @zephyr did not work either.

Have you tried disabling the NVIDIA card from your firmware ("BIOS") settings?
Linux gets confused if there are too many backlight devices
Are any of them failing?
systemctl --failed
Offline
0 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'
In the Asus notebook works me right, this computer worked very well in Terium.
I will try to comment on the BIOS, although I think it does not have the option.

Do the contents of the /sys/class/backlight folder change when you add the Arch Wiki kernel parameters?
We could also try masking the backlight .services with systemd.
Offline
Finally, we have achieved, the bios gives to choose an integrated graphics card intel and the other Nvidia that would be in optimus.
As I do not use it for games until I decide to use nvidia for now I leave it like this and everything is correct.
It was not Helium thing in this case, it was what you said linux is confused with various feedback devices.
Thank you very much for your help .
We can mark it as solved.
