Title:
  Suspend/resume fails with SNA acceleration on some WMs

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  I've installed Ubuntu 15.04 on a new Dell XPS-13 9343 (the 2015
  model). It has a i7-5600U CPU and an Intel HD 5500 integrated graphics
  card.

  On Unity, suspend/resume appears to work fine. However, with the i3
  window manager, it resumes to severe graphics corruption and all text
  gone from terminals (which also become unresponsive). I can kill i3
  using my normal quit key combination, which takes me to an
  unresponsive and blank purple lightdm login. There are no log messages
  out of the ordinary. The same issue appears if I use Fluxbox or
  another "lightweight" WM, but not if I use Unity or GNOME.

  If I configure X.org to use UXA acceleration rather than SNA, however,
  suspend/resume works fine on the affected WMs. (This is why I believe
  the X server for Intel cards is the culprit).

  To reproduce: On an XPS-13 (and probably other HD 5500-based
  machines), start an i3 session and run `pm-suspend`. Resuming the
  machine should produce the error.
