I have this same problem sometimes with Kubuntu 15.10 on a Lenovo Yoga 2
13.3 on resume from suspend-to-RAM. In that frozen state, I cannot swap
to VT-1 though, with Kubuntu. So I just see a black screen with a frozen
mouse pointer. This happens once in every 10 to 20 resumes.

I don't know, if this one helps, or is even a correct additional info: I
believe, that this freeze here (blank screen with just mouse pointer)
happens, when I touch the touchscreen during the initial parts of the
resume process. I've learned to keep my fingers off the screen directly
after resume,

It's not a proper solution, but upgrading to Ubuntu 15.04 might help.

I've created a script to switch to VT1 and back, made it executable,
made it so it doesn't ask for password, then I've assigned a keyboard

Yes, voodoo is a good description of the workarounds I use to get back
to a semi-usable desktop (mainly to be able to save any work).
I usually switch to a VT and issue permutations of the following commands (some
combination often, but not always, works):
$ killall -9 unity
$ unity --replace
$
For me killing unity-panel-service as a last resort doesn't work (anymore).
I am sometimes, but not always, lucky by preforming these voodoo steps:
1) switch to a VT (text terminal, e.g. CTRL-ALT-F1), log in and type startx.
2) It starts another X session, and asks for a password (authentication

Marco: no panel clicking is usually involved. All I need to do to
reproduce it is close my laptop lid. Sometimes the first suspend cycle
works fine, but in that case repeating it a second time always
reproduces this issue.

Hmm. Can you attach a new Xorg.0.log? Next time it freezes, gdb --pid
`pidof unity-panel-server` and type bt -- and please paste the output.

Also worth attaching a dmesg from after the freeze just in case there is

Switching VTs has no effect, tried several times just now. Killing the
unity-panel-service resolved it again. I usually have to kill -9 it,
then a new one respawns, then I kill that one normally, and the lock
screen generally reappears then.

I was hopeful, it worked great a few times in a row, but as I was about

of black, but again I couldn't interact with anything.
Killing unity-panel-service was the solution again. I reported this here

As a first step could you try switching to vt1 and back to vt7 without
killing unity-panel-service. This will help to narrow down the problem.
Switching vt might be enough to get the video woken up, and unity-panel-
service might be a bit of a red herring.
