[Bug 1470724] Re: Xorg freeze - Need to restart lightdm service to be able to type in my password

 

I no longer have access to the laptop and docking station that is
failing and can therefore not perform any more testing on this issue.
Thanks for the  help so far, hope it gets solved for everyone else. I
will leave it "Incomplete" so if anyone else finds this issue and is
affected they can open it.

Title:
  Xorg freeze - Need to restart lightdm service to be able to type in my
  password

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  When I boot into Ubuntu 15.04 it works just fine without the docking
  station but with the docking station I must change tty, login and
  restart lightdm to be able to type in my password.

  ### Expected behaviour
  Laptop in docking station, Unity boots and I can type in my password to login.

  ### Current behaviour
  Laptop in docking station, Unity boots and I cannot type in my password to login. Solution is to change tty, login and restart lightdm service. This is reproducible 100% of the time.
