Check out Armcord. It’s a 3rd party client with many customization choices (mainly due to the fact that it bundles Vencord and Shelter client mods).

I tried editing my config.yml as the guide suggests but the problem persists. The problem seems to be that I’m using MariaDB instead of MySQL (pdo_mysql is compatible with MariaDB). Is there anything more I can do or should I try installing MySQL?

EDIT: Purging MariaDB (Debian repo ships this instead of MySQL) and reinstalling it with sudo apt install default-mysql-server fixed the problem. Thank you.

Which TED talk are you talking about? Can you post a link?
