Hello,

I've been trying to set the Opera user interface to Turkish on my Linux system (Zorin OS 17.2 Core ). I understand that in Chromium-based browsers on Linux, we need to use the --lang command-line switch to change the UI language, as the "Display Opera in this language" option is only available on Windows.

Following the advice, I modified my /usr/share/applications/opera.desktop file by adding --lang=tr in the Exec line, like so:

[Desktop Entry]
Version=1.0
Name=Opera
GenericName=Web browser
Comment=Fast and secure web browser
TryExec=opera
Exec=opera --lang=tr %U
Terminal=false
Icon=opera
Type=Application
Categories=Network;WebBrowser;
MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/rss+xml;application/rdf+xml;application/x-mimearchive;application/x-opera-extension;x-scheme-handler/http;x-scheme-handler/https;
StartupWMClass=Opera

Despite this, Opera still doesn't display the UI in Turkish. I also tried adding Turkish to opera://settings/languages and moving it to the top, but it didn't work either.
