This would happen if you let xorg* packages upgrade ahead of the Mir PPA... xserver-xorg-core 2:1.13.3-0ubuntu2b1 is later than: xserver-xorg-core 2:1.13.2-0ubuntu2+xmir1
The fix is to make sure the Mir PPA gets pinned per these instructions: http://unity.ubuntu.com/mir/installing_prebuilt_on_pc.html Then you will have the Mir version of Xorg installed and it won't crash when passed Mir-specific flags. ** Changed in: mir Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1156946 Title: Xorg crashed with SIGABRT in OsAbort() when Mir installed Status in Mir: Invalid Status in “xorg-server” package in Ubuntu: Invalid Bug description: After installing Mir.
