First I gotta say that I switched from windows to ubuntu 7 months ago, and I'm happier for it.
However, after upgrading to 11.10 (64-bit version) My password doesn't work.
I had originally set up the machine to login automatically and still does so. I just can't make any system changes.
How can I change the password w/o having to export all my data to cloud/external drives and redo the system?
