I just did an fbset with a -g and geometery specs. Ran fbset again to check what I'd set, that was fine. But the screen did something else entirely. Like I'd been manipulating a different framebuffer, but I only see one.
Or PAM/Selinux/Aparmor has been told to not let the user change the framebuffer size, assuming the EDID parser works perfectly so there's no reason to give the user access. I hate that big brother crap. And it's sneaky, I've wasted days trying to do things I was just being prevented from doing with no error messages. But you have to study it to dismantle it and I haven't had the stomach for that yet.
I'll get back to it in a few hours.
