Lenovo Yoga i7 touchpad, touchscreen and function keys (F1 - F10) not working


Since they are not listed in the devices and if no drivers are found, the help of Linux Gurus could be needed.
I have to go to work but check on the magical Goooggle bus (i.e. web search ;) ) . Use your model number, you can't be the only one...
Maybe trying a kernel update/beta version ?

Thank you TheDead,
Function keys work as you said.

However, the touchpad (and touchscreen) is still not working.
It seems that the system does not see them.

In the /input/devices it does not appear and in Control Panel neither.

On Lenovo's, well at least in Windows, you can do a Fn+Esc key combination to "lock" the FN key in Function mode F1-F12. Otherwise, they are in the "other mode", which I don't have a name for since I always use Fx keys.

If the above does not work, you have to une Fn+Fx key for each key, every time.
Note : Maybe there is a Linux equivalenet to my first paragraph though...

For the touch pad, similar idea, it could be disabled using the appropriate Fn+Fx key combination / same for touch.
But, those could be related to drivers, so, do a Driver scan and see where this goes first.


I have installed Linux Lite 5.6 in a laptop Lenovo Yoga i7.
I am experiencing several issues:
    1- touchpad does not work
    2- all function keys do not work. For example, I can not close a window with Alt+F4, I can not rise/down the sound volume with Fn+F2/F3, etc
    3- touchscreen does not work (this is the less I am concerned about)

The laptop is new and all the hardware work, I know because all hardware work properly in Windows.
Using an external keyboard and mouse works properly.

Any help??
Thanks in advance

I am not sure how it helps, but I found that I should check this information out:
