Subject: [PATCH 2/3] gdm-x-session: run session bus on non-seat0 seats
|
|
|
|
GNOME doesn't deal very well with multiple sessions
|
|
running on a multiple seats at the moment.
|
|
|
|
Until that's fixed, ensure sessions run on auxillary
|
|
seats get their own session bus.

|
|
* Always use a separate DBus bus for each greeter session.
|
|
* Firstly, this means that if we run multiple greeter session
|
|
* (which we really should not do, but have to currently), then
|
|
* each one will get its own DBus session bus.
|
|
* But, we also explicitly do this for seat0, because that way
|
|
* it cannot make use of systemd to run the GNOME session. This
|
|
* prevents the session lookup logic from getting confused.
|
|
* This has a similar effect as passing --builtin to gnome-session.
|
|
*
|
|
* We really should not be doing this. But the fix is to use
|
|
* separate dynamically created users and that requires some
|
|
* major refactorings.
