Probably because you're on the VESA driver, which can only use whatever resolutions are embedded in your GPU. The `radeon_hd` driver works best, and on those you can scale to a lot more resolutions; I know some users who run at 1440p.

That's not quite true; we have POSIX multiuser already, so you can `useradd`, `chown`, ssh in to other users, etc. The GUI does not support multiuser yet, but that's partially for BeOS compatibility (on 32-bit), and partially because nobody has had any time to work on it (all other platforms.)
