Bug#802335: gdm3: gdm 3.18 does not switch to the right tty with a multi seat setup

Mon Oct 19 16:20:30 UTC 2015

Package: gdm3
Version: 3.18.0-2
Severity: important

Dear Maintainer,

   * What led up to the situation?

Updating to gdm 3.18 with apt-get dselect-upgrade

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Purged all nvidia packages. Removed all 72-* files in /etc/udev/rules.d
Boot with only the nouveau modules.
Installed nvidia-kernel-dkms.
Reboot
Create the multi seat with:
$sudo loginctl attach seat1 /sys/devices/.../drm/card1
$sudo loginctl attach seat1 /sys/devices/.../usb1/1-1/1-1.4/
$sudo loginctl attach seat1 /sys/devices/.../sound/card1/
Reboot

   * What was the outcome of this action?
After logging in with gdm3 the screen remains gray (background of gdm3)

   * What outcome did you expect instead?
Gdm3 redirects me directly to the desktop. Now I have to press Ctrl-Alt-F2 to
get to my desktop.
