During some experimentation with OpenGL development on the GameShell, I did some investigation into the fbturbo and lima versions being used on the GameShell. While doing so I could not find any mention of fbturbo installed at all:
sudo find / -name fbturbo,
dpkg -l | grep fbturbo, and
sudo apt-cache search fbturbo all yield nothing.
Interstingly, what IS installed and being used, is fbdev, which as far as I can tell is NOT fbturbo, and that fbturbo is a drop in replacement for fbdev. https://github.com/ssvb/xf86-video-fbturbo
Am I missing something here? Does anyone know if it actually uses fbturbo or not? because if it’s not, from what I can tell, fbdev ONLY does 3d software rendering, but fbturbo actually makes use of the proprietary mali binary blobs that should be included in the kernel.
I don’t want to waste my time pursuing this if it does actually already use fbturbo and I’m just not seeing it, but if it doesn’t, dear god if it works better than lima lets get fbturbo working!
P.S. If it turns out that its using fbdev because fbturbo does not work on the hardware, then it should properly say fbdev and not fbturbo for the graphics driver in the settings, specifications, etc.
