yes - if this is unity8 on desktop session, it's using mesa not android. but not sure why x11 would be involved? when running unity8-desktop- session-mir directly on the drivers, not xmir.
also, there was a transition seeding issue discovered on the desktop, where you needed to $ sudo apt-get remove mir-client-platform-mesa3 mir-client-platform-mesa2 mir-client-platform-mesa1 in order to make sure mir picks up the correct platform. might make sure to do that. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1542151 Title: unity8 crashed with SIGSEGV in XGetXCBConnection() Status in mir package in Ubuntu: New Status in unity8 package in Ubuntu: Confirmed Bug description: Just tryed to login after kernel update.
