Are you starting it as root or as your mortal self (unprivileged)? Try
it as your mortal self and not root. It should work either way, but try
it anyway.

The "permission denied" error on /dev/fb0 is odd. You should check the
permissions of /dev/fb0. It should be a character device, major 29,
minor 0, owner "root", group "video" with permissions of "660"
(rw-rw----):

	[root@golem4 bin]# ls -l /dev/fb0
	crw-rw----. 1 root video 29, 0 Apr  2 09:43 /dev/fb0

I believe it's created at boot time (at least mine all seem to have the
timestamp of the last machine boot).

It also appears that you're using a Radeon (AMD) card. I don't have a
lot of experience with them (mostly nVidia and Intel here), so perhaps
you don't have the driver installed? Someone smarter than I would need
to address that.

The final thing I'd validate is that if you have an /etc/X11/xorg.conf
file, rename or move it and let the system sort things out without the
help of that file.

Yeah, that's likely.
