Messed up my Kubuntu install, help please

[zkissane]

I tried to install this driver, no go... I do not know why, but I can not log-in as su in the console. This is the error message:

"su: Authentication failure Sorry."

Yes, the password is correct. I can use apt with this password.

Any ideas?

If you're trying to become root, try

 

sudo su

 

and, if it asks for a password, enter your normal user one. If you've never set up the root user (Ubuntu out of the box has the root account disabled) you'll need to give root a password.

 

sudo passwd root

 

It will prompt you to enter a new password for the root account (possibly after asking for your normal user password to satisfy sudo). That should enable root, and future instances of

 

sudo su

 

should work fine.

 

Remember, if you're using sudo, and it's asking you for your password, it's asking for your user password, not the root password.
