1. THE SITUATION
As of about two days ago, upon attempting to log into my Ubuntu machine, any inputs in the Ubuntu login GUI result in a total freezing of the system. Prior to UN/Password being submitted all elements of the interface behave as expected (to include widgets, mouse, keyboard etc.) The only recourse is to force shutdown.
Ubuntu 16.04 LTS
MSI 64x single boot (UEFI)
Admin boot password is active
Any GUI-based login attempts lock the entire system requiring forced shut down
I've been trying to figure this one out since Saturday morning (almost two days now).
2. KNOWN FACTS
No errors currently exist in the system bios
Live images can boot into both Legacy and UEFI. (Tested with Kali live, Ubuntu Live, Grub2 Repair Disk, and the super awesome USB version of SystemRepairCD )
The projects I was working on prior to the manifestation of the issues at hand involved installing Google Cloud SDK, Firebase, NPM, and NodeJS.
Last week I set up a WAVES blockchain node
The problem likely exists within a PATH conflict. I recall having trouble with some bugs related to NPM and NodeJS permissions and so (as is suggested in the official documentation, and as is suggested by Firebase documentation), I set up an alternative PATH.
Please see the following for reference: NPM: Fixing NPM Permissions
So all of that having been said, the problem remains. Additionally I attempted the following at the GUI login page:
(Control) + (Alt) + (F1)
The command froze my system... Again.
Please assist me with this error as I really need to be operational again before the work-week begins.
Thank you all in advance.
