I’m trying to use a ud-ultcdl with Ubuntu Linux 16.04 on a Dell XPS 13. I’ve got USB keyboard and mouse, ethernet, one HDMI and one DVI monitor attached. I have installed the DisplayLink driver.
It’s proving to be quite unreliable. After booting up everything works for a couple of minutes but then the screens flash and a bunch of the peripherals die. Usually the DVI monitor, keyboard and ethernet but not always. The HDMI monitor plugged into the 4K slot always continues to work.
Powering off the docking station, waiting a minute and powering back on usually gives me a couple more minutes before it goes wrong.
There are a bunch of errors in dmesg:
[115.869055] usb 4-1.1: reset SuperSpeed USB device number 3 using xhci_hcd
[117.590186] usb 4-1.1-port1: Cannot enable. Maybe the USB cable is bad?
[119.074341] usb 4-1.1-port1: Cannot enable. Maybe the USB cable is bad?
[119.661325] usb 4-1.1: reset SuperSpeed USB device number 3 using xhci_hcd
I have tried a different USB 3 cable but had the same problems.
Any ideas? Should I try update 16.10?
