| + | Als nächstes muss jede Tastatur und jede Maus einem Seat zugeordnet werden. Wenn keine Zuordnung vorgenommen | ||

| + | |||
| + | Die Zuordnung geht wie folgt: | ||
| + | |||
| + | Zuordnung zu Seat-X (mit X>0): | ||
| + | |||
| + | Tastatur und Maus in den PC einstecken. | ||
| + | Auf Seat-0 ein Terminal öffnen und als root Benutzer den Befehl **dmesg** eingeben. | ||

| + | Dies muss für alle Eingabegeräte gemacht werden. | ||
| + | Die Aktivierung der Regel erfolgt wieder mit dem Befehl **udevadm trigger** | ||
