I installed ArchLinux on my Lenovo Legion Y720 laptop and I can't turn on Keyboard lights and Extreme Cooling as I could in Windows 10 using Lenovo NerveSense app. How can I access these on Linux? Is it even possible? I've searched everywhere and I couldn't find anything. Should I try coding a driver? Any literature on that?

Thank you!

    The user manual says the keyboard lights can be manipulated with Fn+Space. – Gerard H. Pille Jan 15 '18 at 11:55
  • In Windows 10 it can be manipulated with Fn+Space, because there is NerveSense installed and there is set this shortcut, but in Linux it doesn't work. – Timas Jackus Jan 15 '18 at 11:58
  • Would you mind checking this? askubuntu.com/questions/383501/… – Gerard H. Pille Jan 15 '18 at 12:38
  • I've been here, it's for ThinkPad laptops and it didn't help me, still thanks. – Timas Jackus Jan 15 '18 at 13:14
  • I edited post. About the CPU governor, I should read here? – Timas Jackus Jan 15 '18 at 18:33

Since the NerveSense app is made for Windows 10 and mainly gotten no support for Linux, that way it's far from a reality trying the app working.
