Update: Actually, I tested it again and found that it doesn't work with
the older 4.2 kernel either. Ignore that please.

I see a black screen after an upgrade to Ubuntu 16. If, however, I boot
using the older 4.2 kernel through the advenced options in grub, I don't
see any issues.
I have an Nvidia GeForce 525M GPU. My laptop is a dell inspiron N5110.

It would be helpful if you could test 4.4.3 and 4.4.4. That could tell
us if this is in fact a kernel bug or not.

Title:
Black screen/system
I've just tested again with 4.4.0-10-generic and 4.4.0-9-generic, and
those kernels are seeing the same issue. Perhaps this is a bug in X,
not the kernel? Let me know if you still want me to test 4.4.3/4.4.4.

I'd like to perform a kernel bisect to identify the commit that
introduced this bug. Can you test the following two upstream kernels:
4.4.3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.3-wily/
4.4.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.4-wily/

Same thing on v4.5-wily, although when X died it spit me into a text
login console instead of a completely unrecoverable blank screen
