Title:
  Ubuntu 15.10 freezes with linux Kernel 4.2 (with intel chipset)

Status in linux package in Ubuntu:
  New

Bug description:
  I started with a brand new pc with a fresh install of ubuntu 14.04. But graphics were poor :
  florian@florian-W9x0LU:~$ lspci | grep VGA
  00:02.0 VGA compatible controller: Intel Corporation Device 22b1 (rev 21)
  After some research, I found out that using Kernel 3.19 would solve the problem : it did !
  But External Monitor used to get black (detected and working : sliding windows into it was possible) suddenly after few minutes.
  So I've finally decided to upgrade to 15.10... And freeze happened as soon as login screen appeared, sometimes before at splash logo.
  I changed boot order to Kernel 3.19 to make it work again but "black screen of external monitor"'s problem were still happening.
  Then I've tried to install Intel driver for linux successfully which didn't solve the black screen external monitor problem. Lastly, I tryied one last time to boot with kernel 4.2 with big freeze again again.
