Dell DA200 Adapter not working on Ubuntu

Solution 1:

contrary to what the other answers to this question suggest, the da200 adapter is not a displaylink device (unlike its predecessor, i believe). it's a "docking station" adapter that connects to the usb-c port, and provides hdmi, vga, ethernet, and usb ports.

currently there seems to be a problem with the graphics on this device. the laptop does see an external screen, but it will remain black. only when a low resolution is chosen (usually much lower than the preferred resolution of the monitor or tv that is attached) the display "works".

more information and details about this issue is available from these bug reports:

Solution 2:

This is apparently fixed in the 4.5 linux kernel https://bugs.freedesktop.org/show_bug.cgi?id=92932
