Comment 135 for bug 1308105

Note that there is a Ubuntu package of 4.12.1 available now which can be installed at least without dependency issues on Ubuntu 16.04.

The upstream commit that fixes the issue is here

As mentioned in the upstream bug report: "[...] one issue in the patch; when enabling the crtc it _unconditionally_ sets the output crtc (preferred) mode, rotation etc. properties". Anyway it was decided to merge the patch and address that issue in a new bug #. So maybe the best way is to do the same here, i.e. mark this as fixed in zesty and apply the patch in xenial and yakkety. And create a new bug for the lost screen resolution and other settings.
