I have just bought an Asus. When I log in it logged me as a user:
/home/user>
I wanted to be able to log in as an "su" but it asked me a password which I dont know this just come out from the box. I have tried "root" but it doesn't work. Using "sudo" didnt help neither or may be I put the wrong command.??
please.Thanks
No idea what Linux is installed there. Ubuntu and Debian for example deny per default loging in as root after being installed. You can always su to root, but you have to know the password for this.
Maybe ask where you bought it what password it is. Or check the user's manual for a default password or something.
