There is udev code to detect gpu lockups which will capture i915_error_state in that case, but the general apport-collect script doesn't (we haven't needed it up til now, but probably can't hurt to collect). Since it sounds like that didn't happen here, it suggests you're experiencing something different than a "classic" gpu lockup. In IRC you mention seeing this:
