If it's any use, I booted with the 4.10.0-37 kernel again and run the intel Graphics Update Tool which reported this: Checking if Intel graphics card available... • checking for i915 module in /sys/module • module NOT found, checking for upgraded variant(s) • no active i915 card detected, skipping driver update Checking if Intel graphics card available... OK Retrieving information from 01.org... ...
Note that the i915 module was not found. I run the rest of the intel updater but it didn't install anything. If I boot with the 4.10.0-35 kernel it says this; Checking if Intel graphics card available... • checking for i915 module in /sys/module • i915 module found Checking if Intel graphics card available... OK Retrieving information from 01.org... ... And with this -35 kernel the video is smooth and fast.
