Upgrade to 18.2 on Intel graphics = external monitor unusable

[gmorehouse]

Hello, ever since upgrading to Mint 18.2 Sonya (Cinnamon), I've been unable to use an external monitor on my laptop's VGA port. When I attempt to set it up for non-mirroring, it will go into a mode where it's split (sort of) into quadrants with the taskbar misplaced, and be unusable. This was working fine before the upgrade. I'm not sure what to do next as I haven't had to deal with video failures this bad in a long time.
