yeah, if you don’t have an encrypted drive (which I’m gonna do on a laptop NEVER) on some OEMs this can look semi-seamless.
here’s what it looks like on a laptop:
OEM logo
screen goes blank, backlight off
light on, OEM logo
blank screen
decrypt password
blank screen
loading spinner with OEM logo
gdm/sddm login screen
blank screen
9a. (sddm) loading animation
9b. (sddm) jerk when fractional scaling kicks in
and finally there’s the desktop
with additional mode switching interjected and occasionally the horror that is GRUB inserts a ‘Loading blah blah’ text message; thankfully we’re getting rid of that.
