SUMMARY
The 'Details' Boot Splash Screen, which I assume is supposed to show the verbose text-based boot screen where the status of various services being started is displayed, doesn't work half the time. Sometimes on shutdown I do get the details of services being stopped, but on boot I've never got that - it just shows my laptop's vendor logo the entire time and no text at all.

STEPS TO REPRODUCE
1. System Settings: Startup and Shutdown -> Boot Splash Screen, select 'Details'
2. Reboot

OBSERVED RESULT
On boot, only the laptop vendor logo is shown. On shutdown, sometimes the details screen *is* shown, but most of the time the screen is just blank during shutdown.

EXPECTED RESULT
The text logs of the starting/stopping of the services and stuff should be shown
