Have 12th gen i5 w/ W11. Over the past several months every now and then I will experience no external output from USB-C connection. Normally a reboot fixes it.
Today, I am getting no external display on W11. Dual booting Fedora, the display works fine. So it’s not my monitor, and not the cord.
After multiple reboots, checking if W11 is up to date, swapping input cards as well as swapping input sides, etc I have found no solution.
