Do you happen to have done a force shutdown?
Also, could you share your lsusb
and sudo dmesg | grep apple-ib
whenever you face this issue again.
Two circumstances in summary:
Well everytime you do a force shutdown, the touchbar won't work for the next boot, provided you do not boot into macOS.
If you boot into macOS after a force shutdown, then touchbar will work in subsequent boot of Linux.
Updated fresh install of ubuntu 2.20-4 LTS with t2-ubuntu-kernel (5.15.74-t2) on macbookpro 15". Touchbar shows up as expected on fresh start. However on restart, touchbar does not show up.
