Whoops :-). I think that was me proposing a change in the behaviour,
not me documenting how it works. I suspect that both 1 and 2 (and
probably any other non-zero value) should lead to showing the fps.

Hmmmm, annoying, but there was no harm in trying.

This may well be the cause of the issue. What kind of card is in your
machine?

The repository, with instructions, is here
https://savannah.nongnu.org/git/?group=fluxus

That site is linked to from the pawfal.org/fluxus page under the "get
involved" section. Clearly there are outdated instructions elsewhere.
If you could indicate what instructions you were trying to follow Dave
could update those, if he has a moment.

Well, I think GDM will automatically try to restart itself, that
caused your loop, I bet. I'd try "sudo killall X". Do note that this
(Assuming your X-server is called "X") will cause you to lose all
programs running under X and all unsaved data in those. Depending on
your configuration X may now be automatically restarted in tty7 or you
may need to restart it manually by typing "startx" in the tty of your
choice.

Good question. I'm not sure right now. Our support for error messages
is quite modest at the moment.

No problem. Please report back on whether using the version from our
Git repo helps your issue. If not we may need to look into your
graphics card. If that doesn't help there may be some more serious
matter and I will probably be out of my league. Fortunately we also
have people with more expertise on OpenGL acting up who may have a
moment to spare to help stamp out the issue.
