The keyboard stops working after a while of inactivity like watching a movie or playing a game. The keys light up, and the 2.4ghz indicator on the keyboard shows it’s connected, but my pc doesn’t detect any keystrokes. Only after I unplug and plug the dongle again, does it start working. How do I fix this? Is this an issue on the linux side, or should I return the keyboard and get a Keychron v6 max?
Anything in the logs? Dmesg, journalctl? Sounds like it’s going to sleep and not waking/reconnecting properly. Does it work fine under windows?
Check powertop. See if the device is getting suspended.
