since a firmware update my external screen stopped being recognized. any way to debug this?

more info:

  • I have only one hdmi-usb c adapter so can't experiment with a different one (but this one has worked for me in the past)
  • changing cables did not help
  • changing screens did not help
  • I'm using ubuntu

I had the same issue. Try reducing the resolution of the second monitor using screen , it is apparently an issue with ubuntu graphics driver.
