I'm running Raspbian Buster on a 2GB Pi4, in headless mode (no screen, no keyboard...)
I try to configure my Pi4 for a teamviewer control. The teamviewer's installation was OK, but when I try to connect on my Pi4 it does'nt work...
After investigation, I find that a FrameBuffer is required... something like "/dev/fb0" that I haven't got on my config
I've got a Pi3 (with previous Rapsbian) which have this Framebuffer configurated and it works fine !!
So is the framebuffer diseabled, uninstalled, unconfigured.... and how can I activate it ??
Thanks for your help
