I have an Acer XV340CKP monitor connected via Display Port to my GPU. I also have a old LG W2253TQ that I use as a secondary display. It only has a DVI and VGA port. I have a DVI-DVI cable together with a DVI-Display Port converter to connect to my GPU, which is an Asus RX6900XT. I am running Nobara 38.

I have observed that if I were to have my Acer monitor powered when I switch on my desktop, all the monitor buttons do not respond. None of the menu buttons, not even the power button responds. When I switch off the desktop, the monitor stays on. The only way to power it down is to unplug the power cable.

However, if I were to only have the LG monitor powered when I switch on my desktop, all the buttons on the Acer monitor works.

I believe everything was working previously in Nobara 37. I think this issue probably started happening in the recent month or two.

Is this even possible, where the graphics card sends a malformed signal to the monitor and prevents the buttons from working?

    Unlikely, but who knows? Can you try and boot Windows (install iso probably enough)? Or some very old Linux distro? It might just be your monitor becoming weird with age.

    Edit: Alsobtry with a laptop or something and see how it goes.

      The monitor with this “unresponsive button” issue is the Acer monitor, which is about 2 years old.
