Hello,

I'm running Lubuntu 21.10 in virtualbox. It was running fine. But today Lubuntu asked to do an update via the graphic interface (which I allowed).

Now, when I start Lubuntu within virtualbox, I still get the Lubuntu login screen as usual, but after entering my password and logging in, the screen is black.

I can only see and move the mouse pointer.

So far I have tried only

I'm honestly not sure how to fix that.

What other information can I provide so that somebody can guide me to a solution?

Thanks
