[Multi Monitor] Built-in screen gets enabled changing the entire layout after resuming from the lockscreen

[Luca Osvaldo Mastromatteo]

Hello, first of all I am not entirely sure where to report this

To explain the issue briefly, I have an ASUS TUF F15 laptop and two external monitors connected each to the HDMI and USB-C port with the laptop lid opened but the built-in screen disabled, what happens on the resume from the lock screen (after a couple of minutes, when all the screens go off), the layout gets messed up because the built in screen gets re-enabled automatically, the HDMI screen remains correctly on, but the USB-C screen gets disabled.

I may have a clue on why this happens, I have an NVIDIA optimus setup where the Intel iGPU runs the USB-C monitor and the built-in monitor, the HDMI gets managed from the dedicated NVIDIA card so nothing changes here, and somwhow the builtin screen gets disabled then enabled when resuming the system, resulting in GNOME switching to it automatically as you have plugged in a new screen

No matter how many times you force the screen disabling it, it will happen again.

The workaround is to just to keep closed the laptop lid, of course, but since you can't power it on without the power button is a bit difficult. So I'd just like to keep it open.

Another workaround I found is to unload the asus_nb_wmi and asus_wmi kernel modules as I thought they could be the issue, since they manage this specific platform, but as I said before I am not sure what to expect here, is it the intended behavior from GNOME?

I mean, it's like someone plugs in some screens then the output gets enabled automatically but that's not the case of course, but the asus_wmi module may do some weird things.

What you expected to happen: Resuming from the lock screen with all the screen layout in place
What happened instead: Built-in screen enables itself, USB-C monitor gets disabled, HDMI monitor remains the same, the entire screen layout gets changed
Workaround: Keeping the laptop lid closed or disabling asus_wmi and asus_nb_wmi kernel modules
