I use the BBG. I have a LCD Display Cape attached and I want to use LinuxCNC w/ the Cape and board. I actually tested first on a BBGW. I will test on the BBG w/ additional Cape now.
I am receiving an error. It says that the XServer cannot access OpenGL GLX extension.
I have been up and down the interwebs on this one. I even checked in /home/debian/.xsession-errors on my BBG.
This is where I found a topic of xrandr. So, I looked up what that might entail. It seems everything is already installed that I might be able to use on a Server via the BBG. I am out of options so far. So, I figured, “Why not ask here?”
