[Bug 1581005] Re: Dell XPS 15 9550 Freezes when HDMI is plugged in


The reverse bisect reported commit
63a1281b651b8ebc04c829254c62bd6fbaf83eb0 as the fix.  However, that
commit is a dm merge:

This indicates we went somewhere wrong in the bisect.  We may need to now go back and test each commit again and ensure if the were good or bad.

It might be first worth testing Xenial -proposed, since a few fixes just
went in specifically for the XPS 15.

Do you think you could test the -proposed repo?  If so, see
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.
