How to disable cec?
Hi, I am using bazzite-deck-gnome and have my mini pc connected to my tv in the lounge using an active displayport 1.4 to hdmi 2.0b adapter and it forces the tv to switch to the pc source, I guess using cec. I have used "systemctl disable" to disable all 3 of the cec related services (cec-onboot, cec-onpoweroff, cec-onsleep) but the pc is still forcing a switch to the pc hdmi connection on the tv on boot. Is there anywhere else I need to check to disable cec? I ask because I get shouted at if I reboot the pc whilst other family members are watching tv, as the tv switches to the mini pc input on boot.
