In Intel mode, I can't use hdmi/display port. On reddit, a person writes that on the same laptop and with the same error, HDMI does not work with Intel on Linux without nvidia optimus, but works on Windows https://www.reddit.com/r/openSUSE/comments/s0uzw3/leap_153_cant_get_hdmi_or_dp_output_to_work_on/
