[Bug 966744] Re: [i965] Resume from suspend leaves me with black screen or a screen of the desktop before it suspended. Compiz hung in intel_update_renderbuffers() from intel_prepare_render() from brw_draw_prims()

I got no problems. Try this: add "i915.semaphores=1" to your kernel
options in /etc/default/grub (AND run update-grub AND reboot).  E.g:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash elevator=noop
i915.semaphores=1"


I also do created /usr/share/X11/xorg.conf.d/20-intel.conf with this in it:

  Section "Device"
      Identifier "Intel"
      Driver "intel"
      Option "AccelMethod" "exa"
      Option "MigrationHeuristic" "greedy"
      Option "DebugWait" "true"
      Option "SwapbuffersWait" "false"
  EndSection

^ ^ again, reboot if you do that and/or play with those options.

YMMV.
