I have just loaded Linux Lite on to a Samsung N150 Plus. No problems at all installing it. As a first time user I have what may sound as a silly question.
I closed the netbook lid and password prompt was requested to log on again, I typed in the password I used in setup but it keeps rejecting it as incorrect. I know it is right, as took care to record it.
Any suggestions gratefully received. Thanks
