I have an ASUS ROG GL552V laptop. I want to extend it with an Acer G247HYL monitor but under ElementaryOS 5.1.7 Hera the monitor comes and goes. Interestingly, it only happens when the charger is plugged in. I have 2 graphics card, an integrated Intel HD Graphics 530 and an NVIDIA GeForce GTX 960M. Is this a driver issue? I have nvidia-driver-460-server installed.
I am fairly sure the problem is eOS related as I have dual-boot and under Windows the problem doesn't persist. Under eOS, these blackouts last 1-5 seconds. I can move the cursor in and out of the area, that is, the monitor does not seem to simply disconnect. The blackouts seem to be random and not triggered by any user behavior.
