[Solved] Open type bitmap (otb) fonts not showing.

Tib05 · 2021-02-14 12:47:34

Hey,
I can't get any otb font to show anywhere in any program. I've installed a few otb fonts from the AUR (terminus-font-td1-otbm gohufont-otb, cozette-otb), but none of them work.
I've tried to set the font in GTK applications (gedit, gnome-terminal), there when I look for the font, I see a white entry that I can click (I guess, since the name is supposed to be rendered in the given, it doesn't show up there either, hence the "white" entry), but then, everything disappears in my terminal/gedit editor.

I tried to set these fonts in emacs as well, to no avail.

I know pango support for bdf and pcf bitmap fonts as been removed, and it's written everywhere that otb is the one format than now should work.

I don't know how I can debug this further, and I can't seem to find anyone in my situation.
Thanks for any pointers,

pacman -Qs 'freetype|fontconf|harf'

Is the problem limited to gtk or does it extend to eg. Qt clients as well?

It "seems" to be working in Qt4, in the sense that I can start qtconfig-qt4, select my otb fonts, which preview correctly. When I set them, the entire qtconfig-qt4 window is using the otb font. However, when I close it, it segfaults when I want to reopen it. I've got to delete "~/.config/Trolltech.conf" for it to reopen again.

I mean, qt4 at least comes further than GTK and emacs. But where I really want to get the otb fonts to work is emacs.

Do you have a coredump for the crashing Qt client? (in doubt run it in gdb, https://wiki.archlinux.org/index.php/De … ing_Traces )

Yes, I could produce this:

I'm not sure how I can give more information since qtconfig-qt4 is compiled without debugging symbols. Should I try to supply the core dump in itself?

Oh I just noticed, it says "Floating point exception (core dumped)" actually.

Did you rebuild Qt4 after recent freetype updates?
What about Qt5 clients?

Tib05 · 2021-02-14 17:33:53

No I haven't.
It seems that I solved it now. I'm not sure what was the exact the culprit, but I think removing the folder

~/.config/fontconfig

solved it.
I might have had a janky setting there or something.
Anyway, thanks a lot seth.
