Ubuntu 18.04
ThinkPad T460p

I reject the dock and want to use the dock again.
System hang, usb doesn't work, displays doesn't work.
Nothing but the ethernet connection at the dock is working.

The ThinkPad is working again, if I reject the dock.
But to use the dock again, I need to restart the laptop.

But I can reject the dock and plugin it again, while running the ThinkPad in 
Standby.
Weird.

I attached the dmesg log.

I use the normal nvidia drivers from the repo (v390).
Here is my lspci log (can only attach ONE file):

  ThinkPad T460p
  
  I reject the dock and want to use the dock again.
  System hang, usb doesn't work, displays doesn't work.
  Nothing but the ethernet connection at the dock is working.
  
  The ThinkPad is working again, if I reject the dock.
  But to use the dock again, I need to restart the laptop.
  
  But I can reject the dock and plugin it again, while running the ThinkPad in 
Standby.
  Weird.
  
  I attached the dmesg log.
  
+ I use the normal nvidia drivers from the repo (v390).
  Here is my lspci log (can only attach ONE file):
