Hi Jack,
I haven't been able to reproduce this yet, but I'm on a foreign distro,
and I don't have any fonts explicitly installed via Guix. (For that
matter, I don't have a monitor connected, just now: I've done this with
X forwarding.) I do have a few debugging ideas you could try and see if
they turn up anything interesting:
- Setting the FC_DEBUG environment variable while running can cause
fontconfig to emit debugging information to standard output.[1]
- The command `racket -e "(require racket/draw)" -e "(get-face-list)"`
should print the list of font family names Racket was able to
discover.
- If you start DrRacket at the command line, foreign libraries
have been known to write useful information to standard out/error.
Similarly, if, rather than using the `drracket` launcher, you use a
command like `racket -l drracket`, then you can add additional flags
like "-W" to control Racket's logging system.[2] Racket converts
glib "log domains"[3] to "topics" in Racket's logging system, which
might help get information from some of the related libraries.[4]
(You can also view Racket logging within DrRacket, but it might be
too late to help with this issue.)
- You can try changing the font in DrRacket: if you use the
"Edit|Preferences…" menu item, the "Font" tab is the first one,
conveniently.
Hope some of this helps!
