I wouldn't expect this crash on i915 but we are aware that GL clients like Unity8 will be all-black right now. That's bug 1275398.
Once bug 1275398 is solved then this bug might go away. Last I heard, we should expect that to get fixed when Mesa 10.3.1 enters utopic: https://launchpad.net/ubuntu/+source/mesa -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1381721 Title: unity8 crashed with SIGSEGV in intelClear() Status in Mir: New Status in “mesa” package in Ubuntu: New Status in “mir” package in Ubuntu: New Status in “unity8” package in Ubuntu: New Bug description: I tied the daliy image on my eeepc t91mt but it looks like it crashed on startup.
