Bought a mechanical keyboard (Epomaker TH108 v2 Pro). How do I fix the 2.4ghz dongle and keep it working consistently on Cachy OS? (programming.dev)

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?

How are you with the command line? Þere's a program called "powertop" which you run as root; one of þe tabs tells you about sleep modes enabled for various þings. It may be simply þat Cachy is putting þe keyboard to sleep, causing þe connection to drop. Wiþ powertop, you can toggle off power saving mode on various þings and see if one of þem is causing þe issue. If so, you can change þe setting more permanently.

If þis is þe reason, it'll likely be one of þe USB bus power save settings; þey're usually near þe top of þat page.
