Default Ubuntu 16.04 - no display on Targus ACP70EUZ

I have installed the new Linux driver (DL version 1.1.62) for Ubuntu 16.04 on my Lenovo X250 with a connected Targus ACP70EU.

I see the the evdi modules loaded, but nothing in xrandr, lsusb or Xorg.log ?!? The usb hub part works fine...

Am I missing something?

Hi Termo,

In the logs there is only usb hub part of the dock visible which is consistent with your observations. Quite suspicious, can be even hw fault. Do you have any chance to try this particular dock connecting to any other machine? (can be Linux/Windows)?

Booted up in Windows7 on the same machine, and installed latest driver and rebooted as requested. No USB display adapter - so the same as on linux...

Then while windows running I removed power from the dock, and in again, and then it popped up with a window of upgrading targus dock firmware or something like that. AND NOW IT WORKS!!!

Booting back into ubuntu and it works.

Turning of main display and only using the displaylink, and the display seems very slow (stutter when moving mouse and scrolling windows). I'm running at 1920x1080, is that a problem for displaylink?

Default ASUS MB168B+, 1.1.65 driver and linux 4.5.6 kernel

Have a similar problem with the 1.1 driver.

Set up: Asus zenbook laptop running Fedora Core 23, with an ASUS MB168+ display. Fedora just upgraded the kernels to 4.5.6 and it seems that the 1.0.335 driver no longer compiles with this kernel.

I ultimately just downgraded the kernel to 4.4.9 and went back to 1.0.335 where it works.

When it works I get the following dmesg:

[ 108.065874] usb 2-1: new SuperSpeed USB device number 2 using xhci_hcd
[ 108.077438] usb 2-1: New USB device found, idVendor=17e9, idProduct=ff03

[ 114.879809] [drm] Initialized evdi 1.0.68 19700101 on minor 1


But on the 4.5.6 kernel, and the 1.1.65 do compile correctly here, I only get the
[ 108.065874] usb 2-1: new SuperSpeed USB device number 2 using xhci_hcd

[ 108.077447] usb 2-1: Manufacturer: DisplayLink
[ 108.077449] usb 2-1: SerialNumber: F5LMTF073493

messages in dmesg. It appears that the evdi driver don't get an event or don't recognize the USB device as a relevant one.

Isn't this still a problem with the rpm? If you attached logs, we could be certain about that...

Is X running at that point? I have found the fb device isn't created if X is not running. But remains once X has quit.
Maybe it was co-incidence.
