Note that --on-fatal-error-abort is not a valid option, and just causes a warning to be emitted.
And if you specify a valid option twice, it should tell you explicitly: $ /usr/sbin/unity-system-compositor --vt 8 --vt 8 [2016-10-27 13:29:27.409922] mirplatform: Found graphics driver: mir:mesa-x11 (version 0.24.0) [2016-10-27 13:29:27.411185] mirplatform: Found graphics driver: mir:mesa-kms (version 0.24.0) Failed to parse command line options: option '--vt' cannot be specified more than once. usage: /usr/sbin/unity-system-compositor [options] ... Sounds like either an old out of date unity-system-compositor is installed or something else completely is throwing that exception. I can't seem to make unity-system-compositor fail in a cryptic way like yours. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1634412 Title: Unity8 session fails to start due to unity-system-compositor Status in Light Display Manager: Incomplete Status in Unity System Compositor: Incomplete Status in lightdm package in Ubuntu: Incomplete Bug description: Hi, I've upgraded to 16.10 to try out the latest and the greatest. Unfortunately, the Unity8 session does not work anymore. It was working as expected on 16.04 with the overlay PPA. When I select "Unity8" in lightdm and enter my password, the password box disappears, and nothing else happens. I can still access all the indicators, so lightdm is not completely frozen. I then have to reboot or restart lightdm in tty1 to log in Unity 7. I do have a "system problem detected" warning and I did send the report, but I can't find it on Launchpad, that's why I'm filing this bug manually. I'm using Ubuntu 16.10 64bits, with the opensource radeon driver. Further info from the automatic bug report: Title : unity-system-compositor crashed with SIGABRT in __gnu_cxx::__verbose_terminate_handler() I'm attaching some logs that might be useful. Thanks!
