Bug Description
On boot, Plymouth splash screen fails to appear, leaving a blank purple screen. Blank screen remains even when LightDM or GDM should be displaying greeter/login screen. Login appears to be possible, even though screen remains hidden by blank purple screen. User can switch to another TTY using CTRL+ALT+1 (2, 3, etc) and then reboot by pressing CTRL+ALT+DEL. Sometimes takes 2 - 4 reboots like this to get greeter to appear as expected.
