Title:
  Screen flicker and resolution problems after hot-plug

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to Wily, when I change the configuration of screens
  attached (specifically: dock the laptop to a docking station with a
  vertically larger external screen or open the laptop to activate the
  internal screen while correctly running with said external screen)
  this causes various display issues, including flickering while the
  mouse cursor is moved and or one screen flickering the contents of the
  other; incorrect resolution; incorrect offset of displayed screen
  contents on screen.  I saw similar (can't say whether or not
  identical) effects using the stock 4.1.0-3.3 generic kernel, and
  mainline generic kernels 4.0.0-040000rc2.201503031836 (working before
  the first reboot after upgrading to Wily), 4.1.3-040103.201507220129
  and 4.1.6-040106.201508170230.  In addition (probably a separate
  issue), when booting 4.1.0-3.3 to external monitor only, the mouse
  cursor was not shown.

  After my last test I was able to bring things back to "normal" by
  killing the X server and logging in again.
