Thanks for the clarification.

I suspect the start-up problem has a chance of being a different bug, possibly related to gdm3. So if you agree then please open a bug for that by running: ubuntu-bug gdm3

Back on the main issue here, the data in comment #18 is showing that the tablet always has both HDMI ports present in software, but none are able to detect the TV which is presumably always connected to the HDMI port of the dock. The only thing that changes is whether the dock is connected to the tablet.

Basically this is a kernel problem in which the kernel never detects the TV connected to the HDMI port. So the next step is to report it to the Intel graphics kernel bug tracker, please :)
