The module parameters got removed with 3.2.0. The keyboard backlight is now controled via the /sys/class/leds/keyboard_backlight interface.

These errors are probably created by a lingering /etc/modprobe.d/tuxedo_keyboard.conf and can safely be ignored (or you delete that file and they should go away).

[LukashonakV]

Dear @Matombo I don't see backlight interface at all Which kernel option should I turn on to have backlight interface available

[tuxedoxt]

Hello,

currently you need at least Led Class and Led Multicolor Class options. Other "Class" options would be recommended to allow for future changes.

Hi @tuxedoxt , even I'm still doesn't have backlight driver In the same time there are new errors in dmesg

[tuxedoxt]

Hmm, it complains about version. Make sure the modules build against the exact headers generated by your custom kernel build.

[LukashonakV]

@tuxedoxt , very interesting... I've got 2 packs similar modules. Can you suggest which modules are actual

[LukashonakV]

Thank you @tuxedoxt . Issue is solved. I removed all modules and installed them again. Now backlight is working well. Thank you a lot
