I also have this issue with windows moving after unlock, on 16.04 with
one screen connected via DisplayPort and another via HDMI. When I switch
to both screens via HDMI (one via a thunderbolt/USB-C-to-HDMI adapter)
the problem seems to go away.
This is on a Dell Precision 5510, with the nouveau an
I also have an issue with unity-settings-daemon leaking memory.
Usually after leaving the machine overnight I come in to a unity-
settings-daemon crash, with no crash report due to lack of free memory.
In the last few hours it's gone from 170M to 316M and still gradually
climbing.
This is on 16.
Nice one, thanks. Is this released yet? I'll give it a try when it is
and report back. Hopefully it should fix my issues here:

@shinyblue (and others) would you be able to try the 4.6.0-rc6 kernel?
It looks like some new commits relating to i915 have been made since

I had this issue too with a new Dell Precision 5510 and 16.04 (also
Skylake).
I found setting i915_bpo.preliminary_hw_support=1 seems to help -- any
chance that works for you too?

Assuming this is what's responsible for the issue, to me this is quite a
major bug as it prevents use of external display together with the
laptop screen.

FWIW I still have this issue without Unity and Compiz running, so I
don't think it has anything to do with those. I don't see any relevant
logging from X even after starting it with -logverbose 6.

I am, yes. The only change I made was to disable secure boot, I didn't
enable legacy ROMs and I left UEFI (?) turned on.

Should have said, but this was on a Dell XPS 15 9550, with Windows 10
already pre-installed.
Workaround for me was to disable SecureBoot manually in the BIOS before
booting the 16.04 installer.

Incidentally the wording around this SecureBoot disabling stuff is very
"now or never" -- makes it sound like you'll never be able to install
the proprietary drivers unless you do this NOW, which is slightly scary.
Is that actually the case or can you do this later if you want?
