Trying to enable autologin

Done lots of searching but not getting there.

Enter this into terminal.

sudo gedit /etc/lightdm/lightdm.conf

It then asks for my password, but it's like the keyboard is disabled. I type but nothing happens.

Sorry for the novice questions.

Thanks

So I tried both,

sudo gedit /etc/lightdm/lightdm.conf
and
sudo nano /etc/lightdm/lightdm.conf

Both returned "command not found"

If this is wheezy I think the only stock graphic mode editor is "mousepad", so

sudo mousepad /etc/lightdm/lightdm.conf

should work

OK I tried that and got the same result.

However I first opened Lightdm.conf with Mousepad via the GUI

Made the changes but it won't let me save those changes

Says, "can't open file to write"

That was why after further searching I tried the terminal as stated above

OK I don't know why
sudo mousepad /etc/lightdm/lightdm.conf
did not work but have discovered that
"sudo mousepad" opens mousepad with more authority.

Testing changes now

OK that worked. Thanks fro the help.

If I need that much assistance for such a simple matter, it really makes me wonder if I am the right sort of user for LinuxCNC

EDIT:
Discovered that my error was not leaving a space between "mousepad" and "/etc"

Obviously not accustomed to the rules or syntax with terminal
