Comment 16 for bug 977804

  I still have the issue with "intel_do_flush_locked failed: No space left on device" (Unity 5.12.0, single monitor configuration, i915) in spite of all last available updates were installed.
  I've not tried to change any X.org/driver settings - everything has default values.

  I can try to collect new set of symptoms if required. Additionaly I would change settings if you advice me.

  I have seen message about 2048x2048 of HW limitation during attempt to use two monitor configuration in Unity. But there is no problem with Unity2D: nor with the topic neither with the limit of resolution. The only problem of Unity2D is low speed (at least for me)...
