RE: A folish question

Hello Erik,

Thanks for making the Console/Graphic console thing clear.
Indeed my plan is to get an understanding about the Linux Display driver
Architecture.

I am just aware of framebuffer driver architecture.

	X server
 	 Fbcon
	 Fbdev
	 Fbcon-*

I think this is the way the display driver works.
If I want to write/modify the driver to rotate the screen by 90 degrees,
at which level/files I need to do the modifications in the above shown
files.

Please correct me if I have a wrong understanding about the fb driver
architecture.

Does character rendering means accessing/manipulation the Display card
buffers?
