Ubuntu – How to make FN keys working on Asus G75 laptop



As Tholap said, all I needed was a kernel update, which is effective for a little while now


I just bought a Asus G75 and I cannot make the Fn keys working.
I only found how to control the brightness (http://askubuntu.com/questions/126441/brightness-controls-doesnt-work-on-a-macbook-pro-5-5-ubuntu-12-04-lts) but the other keys are not recognized.

I didn't know much things about key binding before digging, but I tried :

  • testing with xev : no output…
  • testing with keymap : no output…
  • modprobe asus-laptop :
    FATAL: Error inserting asus_laptop (/lib/modules/3.2.0-25-generic/kernel/drivers/platform/x86/asus-laptop.ko): No such device
    (not sure what that means)
  • modprobe asus-nb-wmi : FATAL: Error inserting asus_nb_wmi (/lib/modules/3.2.0-25-generic/drivers/platform/x86/asus-nb-wmi.ko): No such device (not sure what that means)

Thanks for your advice

I have the same problem and looked for a solution. Couldn't find anything that made a difference. The kernel simply doesn't produce any scancodes for most of the Fn key combinations. I guess we'll have to wait for a newer kernel with updated drivers.

This command shows scancodes:

sudo /lib/udev/keymap -i input/event3

Some combinations do work:

  • Fn+F1 - sleep
  • Fn+F2 - toggle wifi
  • Fn+F7 - toggle screen on/off
  • Fn+Del - Ins
