I have asked this question at unix.stackexchange and got paradoxical answers through comments. so decided to ask it again here.
I am going to show Linux desktop environment on a LCD connected to a zynq board with ARM Cortex A9 processor. My idea is to write a driver for its Linux that sends desktop environment displaying data from X server to my hardware.
How can I write driver for kernel interacting with X server and my own hardware to show linux desktop environment?
The easiest way of doing this will be to write a fbdev (framebuffer device) driver for your system. Xorg already supports framebuffer devices, so it will be able to use your display with no modifications; as a bonus, the Linux console can use the framebuffer too.
