ethany,

I do not really remember. Try 13.04 (and 12.04 if it is still in 13.04).
It was one of those, IIRC, that did not have it. Problem is that so much
has changed in the kernel since then. I went through a huge kernel
bisect project to then be told to report it to the kernel i915 group and
got no interest. I am over it, now. I am convinced that the i915 driver
will never be fixed for our particular hardware as it is so old. <rant>
Nobody really cares. Typical 80/20. Get it 80% of the way there then
loose interest in doing the rest of the 80% required to get it 'right'.
Typical of all open source projects. </rant>

As for the last time I tried 15.10, on all of my machines (3 different
hardware, processors, etc), the system just randomly suspends. Without
warning and nothing weird shows up in the log. Just browsing in firefox
or running an app and then bam instant suspend.  It all comes back when
powered on, but not really usable. I just updated and am trying again on
one machine and see if it is fixed. No bug reports relate to this bug,
either. It just did it again. Suspended without warning while I was
typing this.

The latest kernel update for 15.10
4.2.0-23-generic

shows this:

  Resume results in black screen. Graphics can appear completely messed
  up (i.e. torn last jpg viewed over top of latest jpg). This happens in
  Ubuntu 13.10 and 14.04. It happens with: no intel drivers installed,
  and with or without the i915 and intel_agp modules explicitly enabled
  in /etc/initramfs-tools/modules.

  WORKAROUND: Using the following kernel parameters I no longer get the message in the log, the video does not appear to be as crisp somehow, but I can suspend and wake from the command:
  linemodeset=0 video.allow_duplicates=1
