Im trying to set up my laptop so when it's at home, I can use three monitors. I already have it working perfectly with an external HDMI screen. I now want to use the VGA port to add another. Here's the output of xrandr -1 --verbose: (unused modes removed because they're insanely long)
Code:

This shows VGA1 connected, but not having a CRTC assigned. When I try to adjust the monitor positions with ARandR, I get this:

The size doesn't expand to allow the VGA monitor to fit in. Also, trying to apply it anyways I get an error:
Code:
XRandR failed:
XRandR returned error code 1: xrandr: cannot find crtc for output LVDS1
(sometimes instead of LVDS1 it's VGA1).
LVDS1 is my primary laptop monitor, HDMI1 is the working external display, and VGA1 is the new display I'm trying to hook up.
Any ideas? I'm just kind of throwing stuff at the wall to see what sticks, so some help would really, well, help.
