I had two external monitors connected for a long time, one via the HDMI port and the second one via one of the USB-C ports, they both stopped working and no longer recognizes the external monitors.
- I tried upgrading to Ubuntu Ubuntu 20.04.1 LTS to see if it could be old driver but still the same issue
- I tried connecting via USB-C Hub and still doe snot recognizes them
- xrandr --listmonitors does not see them
- The UBS-C is connected via a HDMI to USB-C adapter, and it does recognize the adapter but still no monitor, here is the portion of dmesg:
[ 1532.681263] usb 1-1: USB disconnect, device number 17
