<pre>Well, I'm sorry, but new ubuntu kernels did not fix the DA200 behaviour in my
case (I use a Samsung B523WS monitor and dell XPS 13) i tried
kernel_upgrade_4_13_rc4 and the new kernel_upgrade_4_13, but the result is a
plethora of syslog failures and blank screen on samsung monitor.
When I connect the dongle I get this messages:
<a href="https://pastebin.com/L6DsVDhq">https://pastebin.com/L6DsVDhq</a>
When I connect the HDMI cable I get this messages:
<a href="https://pastebin.com/0wpn6rZy">https://pastebin.com/0wpn6rZy</a>
The main error seems to be:
[drm:intel_dp_get_link_train_fallback_values [i915]] *ERROR* Link Training
Unsuccessful
