switcheroo-control

D-Bus service to check the availability of dual-GPU

See https://developer.gnome.org/switcheroo-control/ for developer information.

Installation

$ meson _build -Dprefix=/usr
$ ninja -v -C _build install

It requires libgudev and systemd.

gdbus introspect --system --dest net.hadess.SwitcherooControl --object-path /net/hadess/SwitcherooControl

If that doesn't work, please file an issue, make sure any running switcheroo-control has been stopped: systemctl stop switcheroo-control.service and attach the output of: G_MESSAGES_DEBUG=all /usr/sbin/switcheroo-control running as root.

Testing

The easiest way to test switcheroo-control is to load a recent version of gnome-shell and see whether the “Launch using Dedicated Graphics Card” menu item appears in docked application's contextual menu.

You can use it to launch the GLArea example application to verify that the right video card/GPU is used when launching the application normally, and through “Launch using Dedicated Graphics Card”.

Or run make -C tests/app install to install a test application that uses the PrefersNonDefaultGPU .desktop property.
