OK. I admit, I should use the Forums more often...
1. I installed Ubuntu to Live USB (System > Admin > Startup Disk Creator)
2. I set a filesystem to store my data (and user info)
3. AND: I just had to remove the default LIVECD account, "ubuntu" (I have full permissions, with SUDO)
1. Everything works fine BUT
2. Every time I go to my VT, I get "Authentication Failure" 11 times on all VTs.
Thanks for your help.
