I'm having a similar problem using a DELL Inspiron 3646 with an Intel
J2900 CPU.

I'm having good results with the following settings:


ALREADY TRIED:


Disable VT-d(Intel Virtualization Technologies) in the BIOS


/etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_pstate=disable"


then


$ sudo update-grub


and


/etc/modprobe.d/i915.conf:

options i915 semaphores=1


then


$ sudo update-initramfs -u



NOT TRIED:



/etc/X11/xorg.conf.d/20-intel.conf
 Section "Device"
    Identifier "old intel stuff"
    Driver "intel"
    Option "Shadow" "True"
    Option "DRI" "false"
 EndSection


/etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
   Identifier "Intel Graphics"
   Driver "intel"
   Option "NoAccel" "True"
EndSection


/usr/share/X11/xorg.conf.d/20-intel.conf:

Code:
Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "uxa"
EndSection

Title:
  Ubuntu 15.04 Freezes Totally

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  If I'm browsing and doing some heavy stuff like streaming or runing
  multiple terminal commands (ssh, wget etc) or watching Video with VLC.
  Ubuntu just freezes entirely - no mouse or keyboard works unless
  forcing shutdown with power button, I can't guess when this actually
  happens, it happens when I don't expect it - even after a fresh boot.
