In the case that /tmp is owned by ourselves and it matches 0200 but not 0022, it is still writable but it would fail with the present error.
I do not know if this is actually an intended blockage and thus the description is just not clear enough or if this is an edge case to consider. Nor do we know whether all the reports here would be solved by allowing this scenario, namely {we are not root, /tmp is ours, /tmp/.X11-unix is at least 0200}. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2069564 Title: gnome-shell crashed with SIGTRAP in meta_wayland_compositor_new() from meta_context_start() from main() ["Failed to start X Wayland: Directory \"/tmp/.X11-unix\" is not writable"] Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: The Ubuntu Error Tracker has been receiving reports about a problem regarding gnome-shell.
