Tdesktop: [Linux] missing font in data-selection

[Translator5]

Linux Mint 18.1
I did delete sth. and now the fonts are not working.
Need some help, what do I need that my fonts are show normal again?

[john-preston]

Is this in Telegram Desktop or where? %)

[stek29]

@john-preston I guess it's "Select file/dir" dialog

[Translator5]

@john-preston Yes this is Telegram Desktop and the "Select file" dialog.
All other fonts in Telegram are working fine, just this in the select-dialog are not working.

[john-preston]

@Translator5 So no fonts only there? They're fine in other places of tdesktop and in other select file dialogs, not in tdesktop?

[Translator5]

@john-preston yes, exactly!

Got this exact issue as well in Ubuntu. Ran Telegram from Terminal, got following output on file selection:

Seems Telegram somehow fails to find Cantarell font though it's installed on my machine. Any clue how to fix it?

Workaround: open Telegram via console as root (e.g. sudo ./Telegram). It will behave as first-time session, so enter and confirm your number and proceed to main Telegram window. Open file selection dialog and make sure font there is now rendered correctly. Now, exit console-initiated Telegram and run it as usual, font for non-root will be fixed as well.

If still not working, run this:

sudo find /usr/share/fonts -type f -name "*.[o,t]tf" -exec chmod 775 '{}' \;

and try again. Script taken from here.

... you want to run telegram as root ;D - I pretty sure I don't trust that much to telegram :laughing: !

I'm also experiencing this.

I'm not willing to run Telegram as root, this gives it too much ability to alter my system in ways I can't track and/or undo. Not that I don't trust the Telegram team, just that it could modify anything (like font files for instance to fix this), and I would have no way of knowing what was changed - that change would then be stuck in my system forever.

Issue is fixed in Patch 1.2 or the 12. Dezember 2017 for me :smile:

i've telegram 1.3.9 and still experience this issue
but i use it as snap
it's so freaking annoying to have such an issue in 2018

[Translator5]

For me it fixed by installing qt5 i thing ... "maybe" ...

[daboross]

~I still experience this with a locally installed or updated Telegram.~

~Switching to telegramdesktop from openSUSE repositories fixed it, but it was still there in the non-distro-specific version...~

meant for #1026- I no longer experience this issue.

[daboross]

oh sorry agh this is the wrong issue. I meant to comment on https://github.com/telegramdesktop/tdesktop/issues/1026, sorry.

[Aokromes]

Test after https://github.com/telegramdesktop/tdesktop/commit/8ee958bfa08b2ba87cffaf8de4b65b6890e59ea3
