I realized I was using the Lyx from the Ubuntu repository. When I removed it, added the PPA, and installed LyX from that -- it now seems to work.
I do, however, have an odd problem where graphics often don't display in LyX, giving errors such as "error loading file into memory" or "error converting to loadable format" which I didn't get before upgrading to Ubuntu 18.04.
