I had Ubuntu 16.04 and suddenly I couldn't log in anymore. Each time I would try to log in, the screen went black and ask again for my password. I was stuck in a login loop. I updated to Ubuntu 18.04 and it fixed my problem, but now the mouse cursor is invisible. I can still click things, except I can't see the cursor.

I use Ubuntu with Parallels in my MacOs High Sierra.


You may need to change your mouse cursor theme (something may have been broken related to this in the upgrade process). To change the cursor theme, install Gnome Tweaks:

sudo apt install gnome-tweaks

Next, launch the Tweaks application and on the Appearance tab you can change the mouse cursor theme. Choose from some of the available options and see if that fixes it:
