I need to disable the framebuffer running on /dev/fb0 via the bcm2708_fb kernel module (reason: some tool I use must run on /dev/fb0 and I need my small TFT to be just that - fb0). Disabling bcm2708_fb in the kernel leads to a few errors during kernel compilation which I like to forego.

I there a known way to
a) have bcm2708_fb in the kernel but
b) not load it, thus leaving /dev/fb0 unpopulated until I load my small TFT framebuffer driver?

According to the source of bcm2708_fb there's no parameters not to load the driver when compiled as a module, according to multiple sources I googled there's no way of not loading a compiled-in driver.

Any help would be highly appreciated.

  • I don't understand what you are doing but have a look at github.com/notro/fbtft – joan Nov 4 '14 at 14:59
  • That's where I got the FBTFT driver from, of course. Please re-read my request: How do I disable a built-in driver that resides within the kernel itself and is not compiled as a module? – Christian Nov 4 '14 at 15:15

You could use fbcp to mirror /dev/fb0 onto /dev/fb1.

See Github: notro/fbtft -Framebuffer mirroring.

  • If you could edit your answer to include a synopsis of the details from the link, then that would be great. – Greenonline Apr 8 '16 at 5:52
