Linux Lite Forums

I installed Linux Lite 5.8 in VirtualBox to teach a friend how to use BASH and learn basic programming principles.  She's remote so I want to use Teams to share my screen, send messages and call.

I'm fluent in BASH, but I'm not fluent in Linux.

UPDATE: solved my problem, switched to VBoxSVGA controller.
