Writing to the Framebuffer

I wonder if there's a way to take over another VT so you don't have the console text over your images.

You can do this without taking over another VT by using ioctl(KDSETMODE, KD_GRAPHICS). This tells fbcon in the kernel to stop drawing console text to /dev/fb.

You can change the active VT with ioctl()s.

See how chvt does it.

I do it with tput civis, and redirecting the output to null.
