Comment 17 for bug 1573959

Also getting this on a 1st gen thinkpad yoga:

$ uname -r
4.4.0-34-generic
$ lspci
...
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)
...
$ dpkg -l | grep xserver-xorg-video-intel
ii xserver-xorg-video-intel 2:2.99.917+git20160325-1ubuntu1 amd64 X.Org X server -- Intel i8xx, i9xx display driver

To add to the confusion, logging in and out of X _does_ fix everything in X. The "real" terminals on F1-F6 are still invisible though.
