I would like to set HTTP proxy for Google Chrome on ArchLinux.

When I open the proxy settings section in Chrome GUI I get:

When running Google Chrome under a supported desktop environment, the system proxy settings will be used. However, either your system is not supported or there was a problem launching your system configuration.

But you can still configure via the command line. Please see man google-chrome for more information on flags and environment variables.

Running it with google-chrome-stable -proxy-server=127.0.0.1:8080 has no effect.

Going to chrome://net-internals/#proxy reveals:

Effective proxy settings

Use DIRECT connections. Source: GSETTINGS Original proxy settings

Auto-detect Source: GSETTINGS

So I use gsettings to set those values.

gsettings get org.gnome.system.proxy.http enabled true gsettings get org.gnome.system.proxy.http host localhost gsettings get org.gnome.system.proxy.http port 8080
