Thanks. I gave it a go but it wasn't playing well with my pixel and yeah, no profiles as you noted. I'll give it another go soon though, thanks for the suggestion.
It's all working as expected but I couldn't get Plymouth rotated without graphical glitches with a gui so I just go no GFX on the SSD decrypt. I think Grub rotates fine.
Omg I have the exact same laptop and have had the exact same issue. Apparently there is a quirk downstream to fix it in the kernel. I had best experience with Fedora and just disabling Plymouth and use no gui for decrypt. I think Grub is ok for me. DM me if you like and want me to check anything specific when I get home so we can compare notes.
Effectively. There’s an MKBHD video which carefully dissects the (minor) differences.
