Comment 5 for bug 1645341

@Onno: no, #4 is a different bug, it's already fixed in kernel 4.7 - see here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1613134
but it may be related somehow, because it depends on the kernel version if it works or not.

To remember:
Kernel < 4.4 = OK
Kernel 4.4 .. 4.6 - touch gone
Kernel 4.7 and later - touch resumed, but finger touch not rotated with screen
