If you are trying to start evince as another user then it should be able to read some Xauthority cookie, but you should experience the same issue with other applications as well. I have no idea if evince might require some extra options related to Wayland when running from simple window managers like FVWM. I hope, it should be enough to have empty $WAYLAND_DISPLAY. Some errors might be logged to ~/.xsession-errors or to systemd-journald journalctl --user -b -e
