i just want to suggest a thing here . I am using Toshiba satellite 'E45W-C4200' and it came with pre-installd Windows 10. it is a touch screen ,and it has a tablet mode. When I switched to a tablet mode i.e. flip the screen backwards, the keyboard and the touchpad used to be disabled automatically and ready to be used as a tablet.
I think this is because of the driver of the magnet found under the keyboard that serve as a sensor when the screen is flipped. But after I entirely removed Windows 10 and installed Ubuntu the keyboard and the touchpad still are functional.
However they couldn't become disabled automatically like before in a tablet mode. To be frank this annoyed me a lot. Currently I use xinput to disable the keyboard and touchpad.
I hope this issue will be resolved when your next version of Ubuntu has been released.
