I just upgraded my laptop to the newest ubuntu version 16.04 LTS and noticed that I can't change screen brightness. I have tried all methods with GRUB which I find in google, but still can't fix this issue. Now my Grub is:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
GRUB_CMDLINE_LINUX=""

With this setup I stuck with the lowest brightness because it's better than sit with max brightness. So maybe someone know how to fix this problem on new Ubuntu 16.04 LTS?

Hi I think that this is a partial duplicate of this post here

If you scroll down there is a workaround using a brightness panel indicator

Good luck.

I made brightness control work. It's not working as good as it was on ubuntu 15.10 before upgrade to 16.04, but it's something My grub now is:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=! acpi_backlight=native
idle=nomwait quiet splash"
GRUB_CMDLINE_LINUX=""

Maybe it would be helpful for someone.
