Surface Pro 4 Touch/Pen requires IPTS

[Ben]

Hardware: Microsoft Surface Pro 4, 4gb/128gb nvme drive

Expected Behaviour: Pen/Touch function

Actual Behaviour: Pen/Touch do not work or respond to anything

Kernel/Ubuntu Versions: All

Cause: Hardware requires IPTS (Intel Precision Touch & Stylus) to function. This is because touch processing is accelerated by the Intel Skylake GPU.

IPTS driver can be found here: https://github.com/ipts-linux-org/ipts-linux-new/wiki

Kernel compile under Debian with other Surface-specific patches can be found here: https://github.com/jimdigriz/debian-mssp4

On Reddit there are some custom kernels floating around with support patched in: https://www.reddit.com/r/SurfaceLinux/comments/4t64zt/getting_the_sp4_running_with_ubuntu_1604/

UPDATE: The IPTS driver needed some updates for 4.10, allegedly this is a working version: https://github.com/axelrtgs/linux-kernel-ipts-4.10
Discussion here:https://github.com/ipts-linux-org/ipts-linux-new/issues/3
The same person has a linux-firmware-ipts, which (again, allegedly) includes the firmware: https://github.com/axelrtgs/linux-firmware-ipts

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Tested with 4.10.0-041000rc7-generic on 16.04 LTS - I do not have touchscreen capabilities on my Surface Pro 4.

Joe, I don't think Ubuntu's ever worked withe SP4; people need to use the special kernel from this PPA for the detachable keyboard to work: https://launchpad.net/~tigerite/+archive/ubuntu/kernel

[mellotron (mellotron)]

I think a good start here would be to set CONFIG_INTEL_IPTS=m in the kernel config.

As of 4.10, keyboard support is in the mainline kernel, though multitouch on the touchpad is not.

However, even though CONFIG_INTEL_IPTS may be there, last I checked IPTS support wasn't actually merged into mainline. Any word on this?

[Sergio Schvezov (sergiusens)]

I've added to apport data to LP: #1670109

For the record, 4.10 is the first Ubuntu kernel to support the 'Microsoft Surface Type Cover' keyboard and touchpad, but the touchpad support is very basic (no multitouch).

For the touchscreen and pen to work one would need the out of tree patches mentioned in the original report.

If anyone's interested in building this kernel without any technical experience, I've added the "Surface Pro 4" build target using the patches provided by axelrtgs to my easy Ubuntu kernel compilation scripts.

I appears that "axelrtgs/linux-kernel-ipts-4.10" doesn't provide a few of the necessary firmwares.
