I created a Ubuntu VM and started following this tutorial to have my clipboard work: https://www.youtube.com/watch?v=qNecdUsuTPw
After running this command:
sudo apt install linux-headers-$(uname -r) build-essential dkms
And clicking in the VirtualBox
Devices->Insert Guest Additions CD Image. Then after it installed I powered off the VM and tried rebooting it but all I have now is a black screen
EDIT: After rebooting it a few times now Im getting the desktop but I cannot interact with it at all...
Now after rebooting it Im either getting this static desktop screen or just a black screen each time I reboot...
