Mount it manually, then. Plug drive in, dmesg | tail to see which
device node it got assigned to, mkdir /mnt/usb , mount /dev/sd?1
/mnt/usb . (It's not that you can't copy files to the disk, it's
that you don't know how to do it.)

No scare quotes around X are necessary. It's an abbreviation for
the X11 Window System, which drives graphics cards and input
devices on Linux/*BSD systems. You probably have an executable
called /usr/bin/X on your system.

No reboot was necessary. Just restarting X should've showed you
if it had worked. Did /var/log/Xorg.0.log change? It
would be a good idea to post that file too, since there are
probably some things in there that would be useful to see. The
whole file, not excerpts, even though 90% of the X log is usually
useless....

Right, so the xorg.conf grep should've showed either radeon or fglrx.
Those are the Free and proprietary X modules that drive those cards.

This is all very strange to me, since installing virtualbox shouldn't
have changed *anything* with the X config.
