Hello all. Thanks for taking the time to check this out.
The problem I want to solve:
I want to make a game in assembly that writes directly into the frame buffer.
The RPi is headless. I connect to the RPi with ssh and vnc to work on it from my laptop.
With my current setup I do not see and of the results of my writes to frame buffer.
When I connect my RPi to a monitor I do see the changes to the graphical output.
I want to be able to connect to my RPi from my laptop, and see the graphical output of the program that directly writes the pixel values to some buffer.
I get the desire to write to a buffer on my RPi so I can see a graphical output that sounds fun. I connect to my RPi using VNC.
I follow a tutorial that writes to the frame buffer. Cool. I compile and run. No graphical output. Hmm does it work on the pi?
I connect the pi to a monitor and run the program. It works! Ok cool. I then wonder what happens if I VNC connect to the same desktop.
I do it and run the program from my laptop. On the laptop screen I see nothing. On the monitor connected to the RPi I see the visual output.
"I want to see the output in the vnc viewer as well" I think. I search for a while then come to these forums.
If you need any additional info let me know.
