Is there any way to detect (on Linux) whether the DP card is toast? It worked precisely once, perfectly it must be said. Then on a second attempt, can no longer detect the display. I can detect all 4 usb-bridges but not the adapter. Is there any way to detect if the adapter just died? Or does anyone know how to get the card detected again?
Maybe as a reply to others: With “hwinfo --short”, my HDMI card is listed under unknown as “Framework HDMI Expansion Card”. My DP card does not show up, leading me to believe that it indeed died immediately.
