Screen/LCD driver for kernel?

I compile the kernel myself. Is there any special option I need to
chose in the kernel so I can use X11 in Ubuntu?

The kernel image I downloaded online has not trouble when after boots
up in ubuntu. The kernel image I compile can't find the screen/video
driver. I guess it's a kernel issue. Not X11 issue.

X11 points to the /dev/fb0, where can I enble it in kernel?
