Thunderbolt 3 Support in Linux for Legion Y720

Is there a workaround to enable Thundelbolt 3/USB-C support in Linux for Y720 devices?

 

I'm getting the "No Thunderbolt Support" in Gnome under Fedora 28 and Ubuntu 18.04 similar to this:

Image result for fedora thunderbolt

 

On the Y720 BIOS, there is no option regarding Thunderbolt configuration or security.

 

I havent tried plugging in an actual device Thunderbolt device though. 

 

I'm also not able to read from a USB-C flash drive.

Re: Thunderbolt 3 Support in Linux for Legion Y720

The interface not showing is not necessarily an issue, the thunderbolt chip basically powers down when not connected to anything.

 

However, I share the ssame of issue of it not working properly with USB devices.

A usb flash drive will work if it's inserted at boot - presumably the BIOS sets it up correctly.

An attempt to plug a device after boot however results in nothing.

 

Haven't had a chance to try an actual thunderbolt device fully yet, but will hopefully soon.

I suspect it won't work either, as the force_power wmi flag supposed to make it turn on does not work either.

 

It works fine for me in Windows, so there's some specific incompatibility in Linux with the Y720.
