[gentoo-user] surface ntrig touchscreen

[Bill Kenworthy]

Has anyone been able to get the surface pro ntrig touchscreen to work
... and if so how?

MS recently changed from the wacom to a ntrig touchscreen (they
apparently bought the company!) for the latest pro models.  The kernel
guys have a surface3_spi module being worked on which I have patched
into 4.6.1 ... but neither dmesg or lspci still shows a ntrig device.

Sorry, never tried...

'lshw' or other hardware scanning tools might show something.


Also install sys-apps/hwids  to the latest version and see if that
hardware shows up.

Depends what you expect to use it for. Linux software is playing catch up.

I would pass the hardware to a Windows VM and use the software that can
take advantage of it.

This is a great place for FOSS development if anyone has the resources.
Currently I am unable to afford a Surface.

Unfortunately no ... the first device is 8086:9d3a which shows up, but
the touchscreen at 8086:9d3e dosent.  The problem is that the detection
code does not enumerate secondary devices - there was a patch against
the spi bus in the kernel a few versions back, but it wont apply to
4.6.1. This is the likely problem but the code is very opaque :(

I'll try and manually add an appropriate stanza in tonight.

This info should be added to hwids upstream. So make contact there
and list the hardware and see if you can get it included.

Munge around the kernel githubs, find the right dev and try that pathway.....

Please post your results. I am able to help. I'm also interested in knowing
if you do it properly.
