Hi Gabriel, please avoid sending such html emails to mailing list as it is hard to read them and also you have a very big chance that email would be eaten by spam filter or other developers would completely ignore it... To debug your problem, can you run smbios-keyboard-ctl tool from the libsmbios project? https://github.com/dell/libsmbios We would need output from --info parameter and also from --get-status. --=20 Pali Roh=C3=A1r pali.rohar@gmail.com From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Gabriel M.

And Gabriel has "Supported Keyboard light brightness levels : 10" and can set only values 0..9. But not 10. Any idea how to solve this situation? CCing Mario from Dell.

The value of > max_brightness is 2, as expected. Ah :-( So you have "Supported Keyboard light brightness levels : 2" and you can se value 0, 1 or 2. And Gabriel has "Supported Keyboard light brightness levels : 10" and can set only values 0..9. But not 10. Any idea how to solve this situation? CCing Mario from Dell. Can you recheck what is wrong here?
