Public bug reported: Here's the global bug for FD passing from unity-system-compositor to unity8 rather than having a socket file.
The general flow would be: *) LightDM gets a client socket from USC *) LightDM sends that fd to logind as a part of the session description (instead of X server number) *) unity8 pulls the fd from logind on startup This then needs an apparmour profile so that dbus denies access to the system-compositor fd from everything that's not unity. ** Affects: lightdm Importance: Undecided Status: New ** Affects: systemd Importance: Undecided Status: New ** Affects: unity-system-compositor Importance: Undecided Status: New ** Affects: unity8 Importance: Undecided Status: New ** Affects: lightdm (Ubuntu) Importance: Wishlist Assignee: Chris Halse Rogers (raof) Status: Triaged ** Affects: systemd (Ubuntu) Importance: Wishlist Assignee: Chris Halse Rogers (raof) Status: Triaged ** Affects: unity-system-compositor (Ubuntu) Importance: Wishlist Assignee: Chris Halse Rogers (raof) Status: Triaged ** Affects: unity8 (Ubuntu) Importance: Wishlist Assignee: Chris Halse Rogers (raof) Status: Triaged ** Also affects: systemd Importance: Undecided Status: New ** Also affects: unity-system-compositor Importance: Undecided Status: New ** Also affects: systemd (Ubuntu) Importance: Undecided Status: New ** Also affects: unity-system-compositor (Ubuntu) Importance: Undecided Status: New ** Also affects: unity8 (Ubuntu) Importance: Undecided Status: New ** Also affects: lightdm (Ubuntu) Importance: Undecided Status: New ** Also affects: unity8 Importance: Undecided Status: New ** Changed in: unity-system-compositor (Ubuntu) Assignee: (unassigned) => Chris Halse Rogers (raof) ** Changed in: systemd (Ubuntu) Assignee: (unassigned) => Chris Halse Rogers (raof) ** Changed in: unity8 (Ubuntu) Assignee: (unassigned) => Chris Halse Rogers (raof) ** Changed in: lightdm (Ubuntu) Assignee: (unassigned) => Chris Halse Rogers (raof) ** Changed in: lightdm (Ubuntu) Status: New => Triaged ** Changed in: systemd (Ubuntu) Status: New => Triaged ** Changed in: unity8 (Ubuntu) Status: New => Triaged ** Changed in: unity-system-compositor (Ubuntu) Status: New => Triaged ** Changed in: lightdm (Ubuntu) Importance: Undecided => Wishlist ** Changed in: systemd (Ubuntu) Importance: Undecided => Wishlist ** Changed in: unity8 (Ubuntu) Importance: Undecided => Wishlist ** Changed in: unity-system-compositor (Ubuntu) Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1324183 Title: [enhancement] FD passing for unity-system-compositor To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1324183/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
