Yes, at least if you look at the thread in their support forum that I posted, they tried to support this but were unable to do so.

Hello, I'm the owner of a Khadas Edge2, and I'm trying to run it with a USB-C DisplayPort (plus touch, plus Power) screen. That combination has historically failed for me, especially with newer kernel versions. There's an old thread in the Khadas user forum https://forum.khadas.com/t/usb-c-dp-stopped-working-after-apt-update/21788 describing the problem, but it went stale and unfixed. I'm not a kernel developer, so I can't fix something like that myself. However, I recently ran an investigation with an agent that, although lengthy, appears to have produced a good fix. It's all in here, the documentation and the result: https://codeberg.org/graphicore/Edge2-USB-C-DP It's based on Armbian. I'd like to see the issue fixed upstream, but since I'm not a kernel developer and I'm neither qualified nor familiar with the norms in that process, I'd like to find someone to take it from here. If there's anything I can do to help and/or support please let me know. Cheers, Lasse
