DisplayLink Forum - Dell D3100, XPS 13 dev. edition / Gentoo Linux

Hi,

I'ven trying to get my Dell D3100 USB3 dock working for some time now and hoped the new driver release will work but it does unfortunately not.

I tried around with different Kernel versions (4.4.7-4.6.0) and different kernel Framebuffer/DRM configurations but the best attempt to get it working was, that xrandr recogniced the connected HDMI display but I did not get the display to receive any data from the Displaylink device after trying to activate it with:

Code:

xrandr --output DVI-1-0 --auto

Here are some debug stuff:

Kernel log from loading the evdi module:
