When a new game is released I usually check if it’s steam deck compatible, if it isn’t for no specific reason (like, a 2d platformer, I’m not going to expect a high fidelity 3d game to work) I’m way less inclined to buy it. The market is there and really should be picked up.
Systemd timer to poll upower when running on battery power, when battery is at 20%, use either system beep or set system volume and play a sound?
