Re: clutter / cogl on Rasperry PI

[Roland Peffer <gdevel clixxun com>]

Hi Patrick,

I think X on Rasperry has not such a good performance as it depends on the CPU.
Wayland or a direct OpenGL ES Surface should be faster.
When I see this http://www.youtube.com/watch?v=HItv4HX5r3k it looks more performant than the X server

Anyway thanks for the answer

I was able to get a clutter ui running directly in X without a desktop on
a PC. Just needed to

export DISPLAY=:0

and then run the app from the commandline. Should be possible on RPi too.
