Package: xserver-xorg-core Version: 2:1.17.2-2 Severity: serious I installed gdm3 from experimental which brought xserver-xorg-core from experimental along with it. This version has support for logind enabled, which apparently is required to run gdm successfully.
There is one particular issue though: Atm, we do restart systemd-logind on upgrades in systemd.postinst. This kills your running X session though, due to [1]. I'm not yet sure, how to address this, i.e. if we can revert this Xorg patch and find a solution in X or stop restarting systemd-logind as part of the upgrade process. I've decided to make this bug RC, since we need to fix that one way or another. Reading [1] again, I remember that systemd now has a facility to pass FDs, which is used to restart journald safely. Maybe Xorg upstream needs to be poked again.
