I tried pressing control L and Alternate at the same time, but it did not release the pointer. Instead, somehow it ended my Gnome session and I had to log in again...
What should I do?
The only time you should have to do that is if the pointer is locked in the VM and you can't click out of it. I have never seen that happen.
I have seen this at least 4-5 times already....
Each time, I have to stop the course, then come back later...
So no way to solve it?
I stop the course yesterday, and came back today.
But it is still locked... (I will try to shutdown the VM)
May I ask what web browser you are using?
