strange video audio and keyboard issue after upgrade

[Felix Wong]

hi,

after updating to kernel 4.18.0-13-generic on ubuntu 18.10, for some
strange reason, audio, multiple monitor detection, and some keyboards
stopped working (all keyboards would be detected as shown by dmesg and
lsusb, but only some of them would actually work).

i am on a intel nuc model NUC6i3SYB.

happy to send whatever info is needed, but not sure what.

thanks,
