When connecting to an external monitor the message is "No USB Type-C signal from your device"
The issue appeared after rebooting my PC this morning and it performed some updates (Not sure what)
While looking around I have found people with issues that xrandr says disconnected even though it's connected but I dont even see any output options. (Shoud have 2 Type-C DP and one HDMI at least.):
$ find /sys/devices -name "edid"

I have also seen this as a common issue with people who have NVIDIA drivers but I only have integrated graphics.
