I installed Evince. Calling it brings up not even a GUI, just two error messages: Authorization required, but no authorization protocol specified Cannot parse arguments: Cannot open display:
Looks like missed DISPLAY environment variable

echo $XAUTHORITY
The last usually points to ~/.Xauthority. 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
