I updated Ubuntu 16.04 in Virtualbox on Windows 7 and now I can only get the desktop background.
I found these questions:
I tried a lot of things all without success, then I tried the steps in https://askubuntu.com/a/801782/574037, getting as far as step 7 before getting an "permission denied" error.
Please help - I'm almost out of ideas.
I have a Nvidia card, if that helps.
