Oracle virtual window user / user account error

After a recent reboot, the Oracle Virtual box with xUbuntu did not instruct user "xxxxx" to login. I can login as root user, I can see / home / xxxxx /, however the development tools environment is configured as user "xxxxx".

here's an excerpt ls -al

at / home / xxxxx /
