At random times Qubes will stop sending video signal to the USB-C to HDMI I have plugged in to my laptop. I just checked the cable with and different a computer and it work as expected.
When I run lsusb in sys-usb it does’t see the cable.
The display is also not listed when xrandr is run in dom0
UPDATE: A reboot will all low dom0 to recognize the display again just trying to figure out why it happens in the first place.
The machine is a Qubes certified NovaCustoms v56
Any suggestions?
