** Description changed:

- I have Lenovo t440s with encrypted root partition, connected to docking
- station and external DELL display. Boot time screen and encrypted
- partition password prompt is shown on laptop screen even if the lid is
- closed, not in the external DELL display. External display wakes up only
- when the login prompt is shown.
+ Lenovo t440s with encrypted root partition, connected to Lenovo docking
+ station and attached to DELL monitor. Restart the system laptop lid
+ closed.
  
- I have had 15.04 for a week. This worked fine before switching to
- systemd, but I don't know if it is related.
+ Shutdown and restart: Boot time screen and encrypted partition password
+ prompt are correctly shown on monitor.
+ 
+ Reboot: Boot time screen and encrypted partition password prompt are
+ shown on laptop screen, not on monitor. External display wakes up only
+ when the login prompt is displayed.
