I am trying to install 32-bit Ubuntu 14.04.3 as a Guest Host on VirtualBox V5.0.6, on Windows 7. Mind you, this is a fresh install. The very first (and all subsequent times!) that I try to log in I get into the infinite login loop referred to elsewhere (Ubuntu gets stuck in a login loop, Ubuntu 14.04.3 going into login loop on Virtualbox, and Stuck in a user log-in loop on startup (fresh install), as well as others) and no joy!
Ubunutu gets as far as displaying the main desktop menu at the top, then a black screen for a few seconds, then back to the login window. Logging in to a terminal, I see the following in .xsession-errors:
init: at-spi2-registryd main process ended, respawning
init: at-spi2-registryd main process ended, respawning
init: at-spi2-registryd main process ended, respawning
init: at-spi2-registryd main process ended, respawning
init: at-spi2-registryd respawning too fast, stopped
init: gnome-session (Unity) main process (2329) terminated with status 1
init: logrotate main process (2226) killed by TERM signal
init: indicator-bluetooth main process (2396) killed by TERM signal
init: indicator-power main process (2398) killed by TERM signal
init: indicator-datetime main process (2400) killed by TERM signal
init: indicator-printers main process (2409) killed by TERM signal
init: indicator-session main process (2414) killed by TERM signal
init: indicator-application main process (2426) killed by TERM signal
init: Disconnected from notified D-Bus bus
Excuse me for emphasizing, but this is a new computer, with latest, just installed, VirtualBox, attempting to install the latest stable Ubuntu LTS, and I cannot log in. Every option was defaults. Nothing tricky. It just doesn't work, and it never has worked! What gives?
I have tried everything that makes sense by logging in via a terminal, but I can't login to the desktop no matter what I try.
The computer is a Lenova T450S, with Intel HD Graphics 5500 display adapter.
Any ideas??? Thanks in advance.
