I recently recompiled my kernel to support the vesa framebuffer for some Directfb fun but now my console outputs text very slowly. It's almost as if turning on the framebuffer caused my console to stop using whatever graphics driver it was before and instead output using the fb. I've searched all around my system for various tty or console configuration files with no prevail.
You would do this in the
grub configuration (requires a reboot to apply the changes).
I wanted to do exactly the same as user3211355: leave the framebuffer enabled, but just don't have the console output going into it.
Took me quite a while, but found it in the end: fbcon was modprobed somewhere. Removing that fixed it for me.
