my mirror has been working for a long time. i followed the instructions about making the screen not go to sleep way back when i created my mirror and it’s worked ever since. however, i updated to 2.13 today (and also did apt update and apt upgrade while i was in there), and now it still works fine, but the screen goes to sleep now. i checked the files i edited to disable the sleep, and they are still edited and up-to-date, so i’m not sure what’s going on. any ideas?
