Whether i click on Shutdown (now) or wait the 59 seconds, on battery or plugged in, my computer goes to a dark screen with static prompt in top left corner. So far i can only shut down from there by holding the power button down. The computer is new to me, and apparently Antergos MATE has been recently updated, so it’s hard to tell where the problem lies. All i can say is it shut down fine under Win 10 until i deleted that OS for Antergos a few hours later.
