Binary package hint: xorg

Whenever I plug my laptop into an external monitor (VGA cable) the display on the external monitor looks very blurry. What should be straight lines seem to be constantly 'dancing'. Under Windows 7 on the same machine it works fine. It doesn't matter whether the external monitor is mirroring or acting as a secondary display, still fuzzy.

The laptop comes with nvidia optimus (hybrid nvidia/intel) but I've disabled the nvidia chip in the BIOS settings, so I'm pretty sure this should be an intel driver issue. I've tried different VGA cables, but they don't make any difference either. I also tried upgrading to the git intel drivers from this repo but they have the same problem.

I tried checking /etc/X11/xorg.conf, but it doesn't appear to exist in Maverick. I also went into the display settings and saw that it said the monitor refresh rate was 60hz and 1980x1020 resolution, just like it should.
