  linux 4.13.0-32 version freezes screen before end of boot for X60
  lenovo laptop

Status in linux package in Ubuntu:

Bug description:
  ubuntu 16.04.3 on x60 lenovo laptop

  previous version of linux 4.10.0-42 works without problems.
  as well older versions linux 4.10.0-38 works without problems.
  even the 4.4.0-96 works without problems.

  at linux 4.13.0-32 the display freezes with 2 top lines fixed.
  however the login greeter still works, you can even login. but you 
  cannot see anything you typed. alt-ctrl-f1 will work. and you can
  see the display working again, however the top 2 lines remain fixed.
  you can do ls and clear, etc. however no gui display. 
  i only installed the linux-*4.13.0-32 packages and it freezes the
  display when you reboot. 7 packages in all. 

  hope you guys fix it.
