Title:
XPS9365 2-in-1 doesn't automatically switch between desktop and tablet
mode
Status in Canonical System Image:

Status in linux package in Ubuntu:
Confirmed
Status in unity8 package in Ubuntu:

Bug description:
Using the current Ubuntu 17.04 image and selecting the unity8 session,
the XPS 9365 does not automatically switch modes.
When switching to tablet mode, the ACPI driver INT33D6 which is bound
to intel-vbtn will emit a few 0xcc events. When switching to desktop
mode, the same driver will emit a 0xcd event.
The intel-vbtn driver doesn't currently send anything to the OS about
these events (just messages in dmesg about unknown, so Unity8 isn't
able to pick them up.
Unity will have to decide what key codes should be picked up, and the
intel-vbtn driver will need to be configured to emit that event.
I think it should be the SW_TABLET_MODE looking through the kernel.
