I just tested FBI and it works for me on buster. what page do you see an issue with the video file?
PiScreen2 works with Buster.
Is your screen all white or black?
White means drivers are not loaded or there is an issue with the screen itself.
Have you done this step?
5. Extra step for Jessie
By default, Jessie will automatically load X out the HDMI port which will then blank out PiScreen which will make it look like it isnt working.
If you want X to automatically load onto PiScreen. Open up the framebuffer conf file;
sudo nano /usr/share/X11/xorg.conf.d/99-fbturbo.conf
Change the below line;
Option "fbdev" "/dev/fb0"
Option "fbdev" "/dev/fb1"
Or, if you would like to disable X from starting automatically, just run sudo raspi-config and look for the option to disable it.
