Heya, just a quick heads up if you are hacking on a multi-seat aware display manager: with current git there is a new property CanGraphical on each seat, and you probably should update your display manager to care for this field, so that you properly handle seats which lack graphical support. The main reason we added this field is to fix a race: when the system comes up it might do so with a text console only, which is then later on turned into a graphical one as the KMS driver is loaded and video probed. We nowadays boot so fast that this might happen at a time where your display manager has already been started, so you need to watch CanGraphical so that you don't end up trying to start X11 on seat0 at a time where the KMS driver is not around yet.
There is also a new variable CanTTY for the reverse, which is handy in some cases for USB graphics devices where the VT logic is not available. This also paves the way for CONFIG_VT less kernels, like the ones David Herrmann is working on. I have updated the wiki to reflect this: http://www.freedesktop.org/wiki/Software/systemd/writing-display-managers Thanks, Lennart -- Lennart Poettering - Red Hat, Inc. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
