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

See for developer information.


./configure --prefix=/usr --sysconfdir=/etc
make 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.

Disabling automatic switch to integrated GPU

By default, on startup and whatever the BIOS settings (which might or might not be available, depending on the system), we will force the integrated GPU to be used so that power savings are made by default, and the discrete GPU is only used for select applications.

If this causes problems, this behaviour can be disabled by passing xdg.force_integrated=0 as a kernel command-line options in the bootloader.

Don't forget to file a bug against your distribution to get the kernel or graphics drivers fixed, depending on the exact problem at hand.

Tested on

  • MacBook Pro (8,2)
  • Thinkpad T430s
You can’t perform that action at this time.
