backlit keyboard shortcut does not work
Hi :)
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 Quote:
Code:
xset led 3 Code:
xset -led 3 this file Quote:
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. My pc Toshiba Satellite p870 Intel i7 3630qm 8 GB ram SSD Crucial 200mx 250 GB Hdd Toshiba 750 GB Nvidia Gf 108 Operating system installed in Uefi Debian Sid Cinnamon with Kernel 4.15 ArchLinux Cinnamon with Kernel-lts 4.14 you're my last hope. hoping for answers. thanks Sorry for my bad English. |

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. but thanks anyway |

sorry, but that's how it is with linux sometimes. not going to bed with hardware manufacturers can have downsides. |
Try running this in the terminal as root. Before running that cmd replace the word sony with toshibia.
Code:
echo 1 > /sys/devices/platform/sony-laptop/kbd_backlight |
@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. Quote:
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. Quote:
Code:
/etc/modeprobe.d/sony-laptop.conf Does the backlight come on during a fresh boot? |
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. looking a little bit, I came across this page of Linus Torvalds on Github, we see the different modules and we see a module toshiba_acpi https://github.com/torvalds/linux/tr...s/platform/x86 and if we look at the composition of the module toshiba_acpi https://github.com/torvalds/linux/bl...toshiba_acpi.c we see on line 123 a report with illumination. so then I looked for the kernel loaded modules with the command Code:
lsmod | more Quote:
Code:
lsmod | more | grep "toshiba" Quote:
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. |
UP !!!
|
I read through the output of lsmod and didn't see anything remotely close to 'light' or a light module.
I'm sorry, I'm out of ideas too. |
it does not matter, thank you.
I go to "abandon" the subject |
