I was trying to tweak Ubuntu after fresh installation and following various links on web stating "Things to do after installing Ubuntu 14.04"
I was trying to remove Guest User Account from the start screen and was following some text in the command prompt. I can recall only few :
- gedit /lightdm/lightdm.conf
and to add below line at the end of already written lines (But it was blank, still I added and saved it). (In the document (looked like Advance notepad :P) which just opened using above piece of code)
3 . greeter remote-login=false
and then reboot.
But here comes the problem. Machine is booting up normally, Ubuntu on purple is coming.... Dots below Ubuntu ticking.... and then black screen.....
I guess I've deleted both accounts (Mine & Guest)? Now it has no entry to let me in. Is there any option to fix it or to get access via a new user account?
I do have a Live USB with me. Can it help ?
Update: I tried to boot in Root prompt while holding shift (when Ubuntu was booting)
and try to edit
sudo nano /etc/lightdm/lightdm.conf it was showing only one line it i.e.
When I try to edit & save it with
[SeatDefaults] it was showing no write permission.
