Hello Gentoo people,

has somebody here got his monitor connected with USB-C (under Wayland?).

Though I followed the DisplayLink/USB-C/Thunderbolt install tutorial on the wiki, it doesnt work.

Any good news that somebody has made it work would clearly motivate my debugging process ;)

lspci -k:

I had to go back to BIOS and change DDI -> mDP to DDI ->TBT to have graphics redirected via Thunderbolt instead of mini Display Port.
HDMI still not working. Its week 5 now :D But at least USB-C and mDP!
