Done, now xdiagnose only triggers if an installed display manager is configured as default but couldn't start. This should fix your boot issue.
We won't fail graphical.target anymore if the only available dm was uninstalled, however, I do recommend you set then your default target to multi-user.target (case on a server system for instance). The lightdm part would be interesting to ensure /e/X/d-d-m is empty, but not required. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1441883 Title: 15.04 Vivid Vervet won't boot after uninstalling lightdm Status in lightdm package in Ubuntu: Triaged Status in xdiagnose package in Ubuntu: Triaged Bug description: We've been trying to figure out how to disable the login screen on 15.04 Vivid Vervet. Our method of doing this on 14.04 was to uninstall lightdm. If we do this on 15.04, however, the system won't boot. :( The main error seems to be: "Failed to isolate default target, freezing."
