Brightness & Touchpad FN keys not working

Post by eduugr »

Hello! I have this problem in Ubuntu and I was able to solve it, but now, the same solution, doesn't seem to work.

I just installed Ming 17.2 with XFCE on an Asus N551JB that comes with an integrated Intel Graphics and a GForce 940M. The installation has
kernel version: 3.16.0-38-generic

I seem to have two *backlight related files*

Code: Select all

edu@edu-N551JB ~ $ ls /sys/class/backlight/
asus-nb-wmi  intel_backlight
And if I run "sudo intel_backlight 10" I can manually set the brightness to 10%, it works.

I followed to solutions but had now success

a) Created '/usr/share/X11/xorg.conf.d/20-intel.conf' with this data:

Code: Select all

Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"
EndSection
Then I logged off and on, and didn't worked.

b) Updated '/etc/default/grub' changing line:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
It didn't worked neither.

The same goes for the Touchpad enable/disable keys (that's very important, it get's annoying when programming).

Thanks in advance for any help or for pointing me out where to look.

Hello ByeByeXP, thanks for your reply!

I just change my keyboard settings to "Asus Laptop" and rebooted but it still doesn't work :/

I really don't know what else to do, maybe there is a way I can check the keymap? something like seeing what are the keycodes that my keys are sending. I don't know but it should be editable...

Thanks !!
