["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

groucho, the next step is to fully reverse commit bisect from kernel 4.4
to 4.5-rc7 in order to identify the last bad commit, followed
immediately by the first good one. Once this good commit has been
identified, it may be reviewed for backporting. Could you please do this
following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

After the fix commit (not kernel version) has been identified, then
please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  multi monitors - black flashes or black screen when the mouse cursor
  leaves a monitor

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When the mouse cursor leaves one of the screens, there is either :
  - no problem
  - the screen becomes black just below the position of the cursor and instantly comes back to normal.
  - the screen becomes entirely black with some random colored pixels flickering on the far left of the screen. I have to move the cursor to the black screen, otherwise it stays black.

  It happens on Ubuntu Gnome 16.04 Beta and Ubuntu Mate 16.04 Beta.
  I have tested with other distributions (Debian Jessie and Fedora) and everything is fine.

  Hardware : Intel Ironlake (Thinkpad X201) with an external monitor
  plugged in.
