I had experience to work with framebuffer and found it pretty well to make own graphical applications. But the problem is that framebuffer is too slow.

My goal:
1) Make a new tty which will work for framebuffer only
2) Avoid framebuffer on other TTYs
3) Provide fast read-write for /dev/fb
*4) Use GPU for framebuffer operations

  • Have you looked into wayland? A lot of the people currently involved with X11 are very frustrated with it.

  • I'd like to avoid any kind of APIs, I need something low level.

  • Wayland replaces X11 completely, it would be about as low level as you'd really want to go.

  • In my question I've asked about framebuffer-like interface, Wayland just doesn't give me it.

Try DirectFB. It handles figuring out which operations can be accelerated in hardware for your display device.

  • It looks pretty nice, but not solution of my current problem. I need something like: couple of commands -> and my framebuffer becomes into separated TTY, couple of code -> I have acceleration.
