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....
So I decided to bite the bullet and did a fresh install of Fedora 39 and that appeared to have made the issue go away. In the process of installing updates and configuring it the way I like, the monitor control buttons on both monitors response. So, it seems like the cause of the issue could have been a glitch during an update. Who knows? At least I know that it’s not a hardware issue (cross finders). :)
I did not try replicating this behavior with a Windows install on my desktop. I did however perform a fresh install of Fedora 39 and that appeared to have fixed the issue, which is good news.
Noticed a strange occurrence where my monitor buttons will not react to presses when certain conditions are met
