Installed latest ubuntu. Password weak so changed it with
$ passwd <username>
Could not then get into it because I'd forgotten password, or something - thought I knew it well.
So entered a root shell in recovery mode. Changed pass word again with the passwd command.
It now accepts this pass word but all I get is desktop background and no menus or anything.
Get impression the encptfs passphrase needs changing. Have the 5ff7.......................... number that was told to write down during install.
What I do to use the Ubuntu?
