Ubuntu 16.10 - Driver 1.2.65 Display not correctly initializing

[bisscuitt]

Hi,

This version (and previous versions) of the driver were working on Ubuntu 16.04.

I recently upgraded to 16.10 and haven't been able to get my external display working.

On connecting the USB device X crashes and the following appears in dmesg:

```

Subsequent re-connections of the device fail to do anything useful.

xrandr shows a DVI-I-1 display as disconnected (this display did not exist until the USB device was connected).

USB device is a Lenovo Thinkpad USB 3.0 Dock - DU9019D1
Bus 002 Device 014: ID 17e9:4302 DisplayLink

Attached is the debug info from DLSupportTool

I have the same problem, did you ever find the solution?

I'm on 16.10 with a new Dell XPS 15 and a 'Dell Dock' as my displaylink adapter, i had this working on 16.04

Can you please raise start new threads with separate problems?

You mentioned X crash - is this raised somewhere already?
We have also seen the regressed performance with Chrome @16.10 - we don't know what it is yet, Firefox is working fine on the same setup with same content. We could use some help understanding the root cause tbh.

Cheers,
Michal

@Matej: the problem you're seeing is this: http://displaylink.org/forum/showthread.php?t=64868 - we have confirmed this only happens with nouveau, and only with certain monitors. Thank you for reporting.

Cheers,
Michal
