backlit keyboard and linux

Question

does the backlight on the keyboard work when installing linux on a laptop?  or is there some application in windows (or mac) that is needed to get it to work?  is it just hardware wired so it will work when installing bodhi?

Not fully proven on my end, but in the case of office laptops I am supporting, the backlights on some keyboards e.g. Acer laptops come on the moment the power button is pushed. From how the questions above posed, my approximate take is that there could be some laptops which have backlights that cannot be functional when a third party OS is instead, but what I observe is that operating system e.g. software control or hardware driver is not always required in turning on laptop keyboard backlights. It's more of an electronics issue instead of software programming, just a guess.  :)

I don't have this issue so might not work/applicable to you.

fitst check if you have vbetool installed

$ apt search vbetool

If you have,

$ vbetool dpms on

If it is not vbetool... try adding

acpi_backlight=video

to the kernel parameter of your grub linux line.

 

Good luck.

 

ps: I cannot go further if this doesn't work.

Others have to help.

 

 

[edit] - one of these .... I just used 'video'; try each one.

acpi_backlight=videoacpi_backlight=vendoracpi_backlight=native
