My VirtualBox Ubuntu Gnome 17.04 installation is suddenly not booting anymore. A screenshot of what I get at boot is attached, it just stays like this. The only thing that I did the last time before shutting the image down was installing the virtualbox guest additions via the provided image. I tried installing lightdm and using that; it loads, but after inserting my credentials it just silently returns to the login screen. Any suggestions?
For those who installed the guest additions from the VBoxGuestAdditions.iso (inserted in the CD-ROM drive) and got in the situation described in this post, this is how I removed them from the command line:
- Switch to a console (Ctrl+Alt+F2).
- Make sure that the guest additions CD-ROM is inserted.
Run the following:
sudo mount -t iso9660 /dev/cdrom /cdrom sudo /cdrom/VBoxLinuxAdditions.run uninstall
I got into this issue with VBox 5.1.22 . Hopefully there will be a fix soon.
When you get to that screen hit Ctrl+Alt+F2. Log in with your credentials and then hit:
sudo apt-get remove virtualbox-guest-x11
To restart the machine:
That will remove the virtualbox display driver, letting you able to log in normally and leaving the functionality of shared clipboard and drag and drop.
