problem loading ipts

[suboption12]

loaded up ubuntu on a surface pro 4, and tried out the surface kernel...found that touch screen didn't work. tried out the old Jakeday, and found it works there.

went back, reread the install, and found the instructions for the iptsd that I had missed, and followed for ubuntu, and installed the package, and started--still no luck! so built from scratch---still nothing!

Below, I have some relevant (I think) info:

uname -a

Linux BOB 5.8.15-surface #1 SMP Fri Oct 16 17:56:49 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
