Just installed the new hardware enablement stack yesterday; all fine.
Today, kernel update to 4.8.0-39-generic ... and after reboot and entering my login password ... nothing. Just my desktop; no mouse pointer; full hang; I have to press the power button to switch of the machine in the end.
Any idea anybody?
Update: turns out the root cause for the crash is a problem with Symantec Antivirus. My company forces us to run that; and although its version 1.0.14.13 compiles with 4.8.39 ... it causes that crash upon login.
At least for me that means that I have to wait updates from symantec here.
