Ubuntu issues?

[MCassimus]

After a clean install I set up my settings and such, do a restart. Then it wont let me log back in upon startup? I have reinstalled 3 times issue still occurs. Video in attachments. Sorry for the horrid quality.

There is the video, doesnt show up well on mobile. I have no idea what to do here.

Looks like the login screen (lightdm) is broken. Try this to re-install it from CLI:

alt+ctrl+f1

Enter you username and password

Enter the following command, hitting Enter after each (you may be asked for you password again since we're using "sudo").

sudo service lightdm stop
sudo apt-get remove lightdm
sudo apt-get update
sudo apt-get install lightdm
sudo service lightdm start 

alt+ctrl+f7

Restart the PC.

Oh, this seems quite promising. Thank you very much!
