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.
