Um, my Linux knowledge is limited with this. I have minecraft-launcher in my
/usr/bin folder, so what I did was I put the following in the terminal and hit
enter

/usr/share/minecraft/
GALLIUM_HUD=fps,requested-VRAM+VRAM-usage,requested-GTT+GTT-usage,GPU-load,num-bytes-moved,buffer-wait-time,num-compilations+num-shaders-created

The game loaded up but I don't know if what you want is working.
