Also did not worked

Hiya , so what've tried so far is , reinstalling xorg and xorg server and then installing ubuntu-desktop for Unity ..


when you switch to a virtual console , run

sudo apt-get remove --purge nvidia-*


This is the equivalent of searching for "additional drivers": sudo ubuntu-drivers list
then use:
sudo ubuntu-drivers autoinstall
After autoinstal , switch to another VT , Ctrl+Alt+F6

sudo service lightdm restart

now switch back to X with Ctrl+Alt+F7 , login .. did you reached the desktop ..!

if you're still unable to login, then i suppose it's time to replace lightdm display manger and try login in with GDM or Slim , or SDDM ..

again , from a VT , :

sudo apt-get install gdm

sudo service lightdm stop

sudo dpkg-reconfigure lightdm

the package configuration window will show ..

select gdm instead of lightdm, press Tab to move to OK, and press Enter.

then $ sudo reboot

It did not work
Now I do not get to the desktop either
It keeps doing a loop as if it's trying to get to the desktop
I tried to press Ctrl + Alt + F1-6
But i can not
I do not have the time to enter a user name and password
Because it's all the time in the loop

Did you install the Nvidia's driver using the .run file !

[BenginM]

You don't happen to have an xorg.conf.XXXXXXXX in use, or do you!

if you purged Nvidia-* , then nouveau is loaded to be used ..

You didn't conform , did you replaced lightdm with GDM!

[BenginM]

Are you able to boot into recovery mode ,and drop to a root shell !

And for future reference , this is how one's supposed to install Nvidia's driver :

I just tried it
And I have a possibility

What options do I have to choose and what to do exactly

I still don't know how you have installed the nvidia driver, so i can't guide you , did you used the additional drivers GUI section or used the nvidia installer .run file from nvidia.com!

These are the steps I have taken

when in logging desk top

Ctrl + Alt + F1
then

sudo apt-get remove --purge nvidia-*

then

sudo ubuntu-drivers autoinstall

Ctrl+Alt+F6

sudo service lightdm restart

It did not work so I tried the second part

Ctrl + Alt + F1

sudo apt-get install gdm

sudo service lightdm stop

sudo dpkg-reconfigure lightdm

i select gdm instead of lightdm

then

 sudo reboot

That's it
