How linux os handles 2D graphics: fundamental doubt.
To my knowledge, linux boots into text mode. (Correct me if I am wrong.) Then it switches to graphical mode. Which library in linux handles the graphical drawings like line, rectangle, circle, pixel etc? I mean, where is the code for drawline, drawcircle, drawpixel etc? Is X responsible for doing all these? Where can I find the code for these functions for linux os?
