Is there any documentation / guidance on how to customize
.desktop files bundled into a snap?
For example with chromium I need to add the
--proxy-pac-url argument to all
Exec= lines in
You can’t just edit those file directly as the snaps are mounted readonly.
I’ve set the environment variables for
auto_proxy (both lowercase and uppercase variants), and confirmed that they are shown if I run
snap run --shell chromium and list the current environment variables (
env), but chromium appears to ignore them.
I can get chromium to correctly run via
chromium --proxy-pac-url=file:///etc/proxy.pac, so i just need to find a way to amend the desktop files accordingly.
I’ve read that you can override desktop files by placing amended copies in
~/.local/share/applications and running
update-desktop-database ~/.local/share/applications, but now I have two icons in the launcher (one for the default, and another for the amended version, rather than overriding the original). Obviously I could amend the
Name= for the amended version, but it’s still not ideal.
