since I've been on Linux it's impossible for me to control the lighting of my keyboard on my Toshiba Satellite p870 laptop.
With windows, there was a software (Toshiba Function Key Utility) that allowed to manage the backlighting via the FN + W shortcut (Azerty keyboard, I'm French)
In bios, there is an option that allows you to
* to turn the keypad off completely
* permanently turn on the keypad
* switch off the keypad after X seconds
Despite a great deal of research, I did not find any solution.
The return order
Code:
ls -l /sys/class/leds
gives me this

the command
Code:
xset led 3
and
Code:
xset -led 3
has no effect on keyboard backlighting.
this file
Quote:
/sys/class/leds/toshiba::illumination/brightness
does not exist......
the acpi=off in /etc/default/grub option triggers a black screen at startup.
Is there a way to manage backlighting with a keyboard shortcut??
using a script or something??
Since my first days on Linux, I've been looking for a solution, and I haven't found it yet... I really despair....
It's so convenient that kind of shortcut, it's something I miss so much.
I've already searched, but I didn't find anything useful..
I've been searching regularly on the forums for a year and a half, and I'm still at the same point...
I need help or a script idea or something like that.

sometimes that means that what you're looking for just isn't there.
sorry, but that's how it is with linux sometimes. not going to bed with hardware manufacturers can have downsides.
@Ztcoracat
no such case....
In Nemo, I did a search with the keywords
"" Backlight, illumination, kbd, toshiba, and led."
And the result is clear, all files and folders have nothing to do with keyboard backlighting.
@Ztcoracat and @ondoho
I set the backlight in the bios to turn the keypad off after 45 seconds of inactivity.
If Linux succeeds in reacting to the bios parameters, it is because the shortcut fN + w can work.
Especially since I noticed something.
when I press FN + any letter, the letter is well written (than tonight on Firefox, Mousepad, Libreoffice, or anywhere)
But if I press FN + w, the letter is not written, so the shortcut is still known...??
But it remains inactive, why.??
because the Toshiba Function Key Utility? software is missing.??
What did the konsole return when you ran that cmd?
I don't think it's software that's missing I think it's a module.
There are hundreds of modules in the kernel, sorry I don't know which mod it is.
Maybe look in the config file for the kernel and look under light.

I think it's because the module for the backlighting is missing or something that is associated with the backlighting it'self is not in the initialization script at start up.
I've had Slackware, Centos, Ubuntu and Fedora installed on my laptop and the backlight worked.
However, when I installed Linux Mint the backlight would only work if I ran that cmd as root each time at start up.

That's why you have to create one like this I think:
Code:
/etc/modeprobe.d/sony-laptop.conf
Did you make a /etc/modeprobe.d/toshibia-laptop.conf?
the creation of the toshiba file in /etc/modprobe. d doesn't change anything...
The backlight works from the pc boot, and stays on for 45 seconds before turning off (the settings I specified in the bios)
but the FN + w shortcut does not work on Linux.
toshiba_haps :
is to protect the hard drive in case of a fall.
and bluetooth toshiba.
But I don't have toshiba_acpi, why...??
you need to install acpi packages..??
because I don't have any of them installed..??
I'm starting to run out of ideas.
Thank you very much.
