Lately my Stream Deck has not been accepting “mouse” clicks, whether it be my trackball, the touch pad on my keyboard, or the Steam Deck’s own hardware buttons. A restart of the deck had been working, but today it does not. Also now when restarting, the Deck boots into game mode instead of back into desktop.
Anyone else have this issue and find a solution?


This sounds like some invisible app is open and intercepting the clicks. If you can get into kDE’s settings configure it to always start an empty session and not start the same programs that were open when it shut down. Maybe you can get to that window by alt-tabbing.
It is looking more and more like it is Bluetooth related. After my initial post I discovered I could click on the Bluetooth icon and then navigate using my keyboard to the on/off slider. Once I restarted Bluetooth and reconnected my devices I could click again.
Yesterday I stopped by work (been home sick since Thursday) and grabbed my usb keyboard and trackball, since connecting them (they are what I use at work with my Steam deck) I have had no issues with clicks.
