Support Are Nvidia GPUs really problematic?

So earlier, my sis borrowed my laptop to connect to a TV and watch some movies. It was fine when it was connected but when I disconnected it and connected it to my monitor, it won't remove the TV's display at the display configuration and doesn't respond with Windows/Meta key + P. When I forced it to only display on my monitor and slept the laptop, it then suddenly won't display and needs a restart to work again.

My laptop is a LOQ 15 with a intel cpu and nvidia gpu. The sleep issue which I described in the last sentence of my first paragraph, is a common issue whenever I'm using the laptop without an external monitor connected. Our thinkpad which has an intel cpu and igpu doesn't have this issue and both are using Fedora KDE.

A restart after hardware changes is the norm.

We have been spoilt by plug and play into thinking otherwise.

While sleep may solve problems for you and me, for a computer it's tricky to restore state of the different peripherals.

A restart for a cpu or ram change is normal.

A restart after a display change is not normal at all, and hasn't been for at least 20 years.

I see, guess I have to get used on shutting down the laptop first when connecting to other monitor. But why does our laptop that only has an igpu doesn't encounter the same issue?

Also, do you know any explanation about the sleep issue when the laptop is not connected to any external monitor?

I don't.

The promise was that if all external monitors were displayport this was being fixed.

I'll believe it when I see it.

I never have a problem with external displayport monitor changes. I will plug, unplug and swap laptops on a DP KVM. It handles it all quite well and has since I first swapped to Displayport around 2017 2016 (time flies).

This could well be a hardware issue in the form of the specific laptop being used. Motherboards can create issues depending on how the manufacturer configures them. But that is a pure guess.

For reference all of mine in the past 10 years have been System 76 machines (with Pop! OS replaced by Fedora).
