Nheko is a multiplatform Matrix client written in QT6. Unfortunately on Ubuntu 24.04 due to a bug changing the default font 1 leads to a crash at startup. This means that the GUI is inaccessible to roll it back.
The solution is to edit the config files directly. For a Flatpack installation:
bash
# access the flatpak shell
flatpak run --command=bash im.nheko.Nheko bash (im.nheko.Nheko) ~ $>
echo $XDG_CONFIG_HOMEThe output will be in the form $HOME/.var/app/im.nheko.Nheko/config, navigate to it and open the nheko/nheko.conf file.
ini
emoji_font_family=default
...
font_family=defaultRestore the font family settings to default.
Why would you want to change fonts? Well, it’s messaging app and I want to display emojis sometimes. ↩︎
