Graphical session crashes if two external monitors are plugged with DisplayLink dock

[vampirex]

Hi Kabouik,

My setup is very similar to yours, almost identical. Though our laptops are slightly different, the specs are pretty much the same. (I am using a Lenovo Thinkpad X1 Carbon.)

The only differences are:
- Using Kernel 4.5
- Main laptop monitor max resolution is 1600x900
- 4GB of RAM
- GCC 5.2.1 & 4.9

Thought, I am able to use 2 monitors @ 1900x1080, but it didn't work off the bat, had to do a few reboots and playing around with the cable.

There has been a few issues that I've experiencing:

- Dock Disconnections
- Session logs out when 1 or more monitor turns off
- Both mouse and keyboard lags (wireless)
- Timeout on Data transfer over Ethernet
- System Freezes

Most of these problems occur after the system has been in suspend mode, so a reboot usually fixes it.

In your case, maybe try re-installing the drivers?

Can't wait for the new drivers.
