This happened to me just now when installing Ubuntu 14.04 on Parallels Desktop 9 (Build 9.0.24229; Revision 991745; Tuesday, April 1, 2014) for mac (OS 10.9, Macbook Pro) .
The Ubuntu install finished fine as long as I unchecked "Express install" during the new VM setup/install.
After Selecting "Intall Parallels Tools...", my Ubuntu desktop looked identical to the original poster's.
Ctrl-Alt-T didn't open a Terminal in this state either. I had to do
Fn to enable the F-keys instead of brightness etc.) to get a terminal, log in, and then follow these instructions on the Parallels Desktop website:
Worked perfectly and got Ubuntu (and unity) working properly again.
The instructions from the Parallels Desktop help site are copied here (copied on 2014-05-25):
- Start your Ubuntu 14.04 virtual machine and press Ctrl+Alt+F2 to activate the command line
- Enter your username and the password
xorg.conf.XXXXXXXX (where XXXXXXXX is a current date when the xorg.conf file was created) via:
ls -l /etc/X11/
- Check whether this file contains "Parallels" entries, via:
- (see orig. Parallels website for what the xorg.conf.xxxx file should look like)
- Ctrl-X to exit pico (or exit whatever editor you used)
Then Type in the commands:
sudo mv /etc/X11/xorg.conf.XXXXXXXX /usr/share/X11/xorg.conf.d/xorg.conf
gsettings reset org.compiz.core:/org/compiz/profiles/unity/plugins/core/ active-plugins
- Press Ctrl+Alt+F7 to exit the command line
- Reboot your virtual machine.
Actually, because the unity GUI didn't show any obvious way to reboot, I stayed in the command line (ctrl-alt-Fn-F1) and used the command
shutdown -r now
