I am experiencing the issue where my console becomes completely

I have tested some potential work arounds for console lockup when the unity

To avoid restarting and losing all unsaved data, I did the following:

This bug continues to exist in 16.10. Just had a freeze, was unable to
interact with the system in any way (could not drop to tty1) - requires
hard reset on my system.

Here is the same problem in Ubuntu 16.04. By blocking the session, the screen
goes black. By accessing the tty1 and end the process of compiz, you can log in
again.

Hammeh, can you connect via SSH to the machine or access from tty1 to
it?
As if you can it would be nice if you could install the debug symbols
for unity and compiz, and attach to the compiz process with gdb in order
to get a backtrace.

Still a problem in Xenial 16.04. I'm using Intel gfx driver so based on
others using different video drivers (ati, nouveau and now intel) may
indicate the problem lies at least not with the video drivers.
Perhaps it's a problem with Unity's lockscreen?

Still exists I think. I am facing this issue since last week.
I have noticed that it happens when I am using netbeans (maybe OpenJDK
issue?), when the screen locks for idle, I can login but then I can not
set focus to any window other than netbeans, and at the same time can
not use netbeans.

I am also experiencing this one, it is annoying (if I put it mildly).

Not sure if my problem is due to the same reasons, as the lock screen is
completely frozen - cannot even `Ctrl+Alt+F1` to go to tty, and mouse
will not move. Otherwise exactly the same: Screen when going to locking
manually using `Ctrl+Alt+L`works fine and responds to mouse/ keyboard.
