So.... the giant pain in the backside that is called ubuntu upgrade

isnt over...its a long stupid story.... however I did find a solution
that at least let me reboot into a gui

Lets start with ... the ONLY  way I could make any progress, was erasing
my hard drive and installing from scratch.... (%^$# YOU ubuntu)

 it all worked and booted.... then I spent the next way too many hours
trying to get all my stuff back up and running.... configuring
...installing... customizing... blah blah blah

so... since I am obviously a moron (for trusting an upgrade in the first
place) I today was a super big moron and installed the nvidia drivers
and various issues happened... I run 3 - 27 inch monitors running in
panorama and the default from the install was fine..... and
everything...so why I thought I should fix it by adding the propriety
driver is beyond me

regardless a number of crappy things happens that made my work day turn
into once AGAIN.... "lets f around with ubuntu day"

after installing the driver the damn thing kept booting into low
graphics mode with no solution in site... so I started trying to solve
that problem and found this

in-low-graphics-mode-error/141607#141607

This is a bug in LightDM and a bug report has already been filed.

The reason why you end up with this failsafe X is because the pantheon-
greeter you installed along with the elementary desktop is now not
available and LightDM is not able to identify an alternative greeter.

As a workaround, you can edit the LightDM conf file and correct the
error.

Run the following command in a terminal:

sudo nano /etc/lightdm/lightdm.conf
and change the line

greeter-session=pantheon-greeter
to

greeter-session=unity-greeter
and save it.

After changing the file, reboot and you will now be greeted with Unity
greeter.

****************

so I did this .... and somehow ... inattention...frustration... anyway I
erased the contents just before I hit the save & rebooted

to my HORROR... I booted into the same problem that started this
mess.... the bug described... so Im 2 days into a re-install and back at
the issue I had that started it all, that I had no solution for in the
first place other than a full re-install....

Since its almost halloween... i guess... nightmares are appropriate


anyway all the whining aside... I figured out how to at least get it to boot back to low graphics mode, so if you are stuck at the 
point you login and then nothing happens you can at least try this

cntrl alt F1

login

sudo nano /etc/lightdm/lightdm.conf

I edited lightdm.conf to:   greeter-show-manual-login=true    (this is
different from the suggestion in the link)

saved and rebooted and I was at least able to get into low graphics
mode, back to the last fing issue... but even that is an improvement! I
was about ready to eat a bullet at that point if it hadnt worked

I hope it does for you... I was not able to find any way in other than a
full re-install before....

Apparently this bug is at least in my case related to this

So.... now I can boot into ubuntu,,,but I have been hosed by the new
drivers... can someone please tell me how to FULLY remove all the nvidia
crap and restore the default generic driver
