Hi, Because of the naming change, it becomes difficult to create scripts to pe-configure display priority, resolution, position, and etc. In my case, I have a device with Intel iGPU AMD dGPU, and I want to pre-configure display priority when more than one monitor are connected to the system. In my own environment, I use xorg.conf and udev rules for hotplug detect, and it works because those names don’t change. However, if I bring the device to work, configuration needs to be changed again for different monitors. Further more, except for MST monitors causing name difference, I see different names when primary GPU is changed from one to another. I don’t know if there are better solutions for this, to have designated output names for display interfaces.
