DRM Lease a HDMI TV

Hi!

I want to prevent GNOME to show overview and alt+tab on my TV.
So I made an application to drm lease my TV, but I couldn’t get any connectors. I then tried using the linked kmscube test app but it failed at a connector assertion.

I did try to run this session:

[Desktop Entry]
Name=GNOME (Debug Lease)
Comment=This session is for debugging DRM leasing.
Exec=env MUTTER_DEBUG_LEASE_CONNECTORS=HDMI-1-A gnome-session
Type=Application

still no result.

I am missing something?

Thank you!

By default non VR output devices are not available for lease, you need to make them that explicitly. You can either do that by editing ~/.config/monitors.xml, or using the gdctl command line utility. Search for --for-lease-monitor in man gdctl.

Thank you. I didn’t know you had to disable the monitor first.
I even compiled my own version of mutter to try to disable the check :slight_smile:
