    * At the moment, '''Xubuntu''' and '''Lubuntu''' do '''not''' support per-seat automounting of removable media, even when booting with systemd as PID 1. In '''Ubuntu''', '''Edubuntu''', and '''Kubuntu''', when a storage device is plugged in a given seat, all seats will be notified, but only the right seat will be able to mount it. On the other hand, '''Ubuntu GNOME''' offers the best support for this feature (when a removable media is plugged in a given seat, the other seats won't be notified).

Introduction

The MultiseatTeam maintains packages in the multiseat PPA. These packages are Ubuntu packages that have been patched to improve support for multiseat.

Known Issues

  • DVB device ACLs and MythTV: udev and logind want only logged-in users to have access to attached DVB devices. This is accomplished by setting up /dev ACLs when a user logs in. Unfortunately, this conflicts with MythTV, which always wants access to the TV tuner device(s). I'm not exactly sure how to fix this. Modifying /lib/udev/rules.d/70-uaccess.rules and 70-udev-acl.rules and commenting out the dvb lines seems to work, but is fragile -- those files will be replaced the next time systemd-services and udev are upgraded. udev apparently doesn't provide a way to remove a tag once one has been set, so putting a new file in /etc/udev/rules.d won't work. Anyone have any ideas?

  • bug #976124: On some systems, only one user can be logged in by typing a password at a time. All other users must be automatically logged in via LightDM's autologin-user setting.

  • Due to a technical limitation in Linux's virtual terminal subsystem and how it interacts with X, only seat0 can switch users. To switch users on another seat you must first log out and then log back in as the other user. Perhaps Mir, Wayland, and/or kmscon will address this.

  • LightDM is unaware that user switching is unsupported on non-seat0 seats. It will allow you to try to switch, but fails to switch.

  • bug #1190581: Automatic multiseat support has not yet been implemented.

ChangeLog

2014-04-24

  • introduce trusty udisks2 package rebuilt with full systemd-logind support, needed for correct per-seat automounting of removable media.

    • PLEASE NOTE: you'll also need to boot Ubuntu with systemd as PID 1 in order to get this feature fully working (see this page from Martin Pitt's blog for more details). Without this step, only one seat will be able to mount removable media.

    • At the moment, Xubuntu and Lubuntu do not support per-seat automounting of removable media, even when booting with systemd as PID 1. In Ubuntu, Edubuntu, and Kubuntu, when a storage device is plugged in a given seat, all seats will be notified, but only the right seat will be able to mount it. On the other hand, Ubuntu GNOME offers the best support for this feature (when a removable media is plugged in a given seat, the other seats won't be notified).
