I want to create one virtual frame buffer device as i don't have any hardware device and I want work on graphics stuff using frame buffer under Linux System.
Is there a way to make or create Linux framebuffer device (e.g. /dev/fb0 or /dev/fb1 backed by virtual framebuffer) as a real display?
Ideally it should appear in system display settings as a configurable monitor.
Does it require writing some kernel code or it's possible to somehow get away with for example editing X config files or using xrandr?
Please let me know if any one has idea about this.
Maybe you can used XVFB to emulate virtual framebuffer
