From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This latest UKI work for Fedora will lead to better UEFI Secure Boot support, better supporting TPM measurements and confidential computing, and a more robust boot process.

and HOPEFULLY lead to a less jerky-flashy-switchy boot xperience, looks like a Vegas light show at present. switched to systemd-boot, but it's only a tiny bit better, still switches modes/blanks screen like five times.

Mine only switches modes once, on load save backlight.

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:

1. OEM logo
1. screen goes blank, backlight off
1. light on, OEM logo
1. blank screen
1. decrypt password
1. blank screen
1. loading spinner with OEM logo
1. gdm/sddm login screen
1. blank screen
9a. (sddm) loading animation
9b. (sddm) jerk when fractional scaling kicks in
1. 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.

My HP crapbook doesn't have this OEM logo bullshit. Only the windows bootloader shows it, and the logo file is stored in the BGRT. So I don't think I'm affected unless the WBM or systemd-boot have this vuln.

Mine:

1. Screen turns on
2. I pick EndeavorOS in systemd-boot
3. It starts spitting out logs (I love this behavior)
4. It switches modes once the backlight is loaded
5. I log in
6. KDE loads

I will never understand people who install Plymouth, it just adds complexity in the boot process. If your distro installs this then I understand why: so it doesn't look like you're "hacking the government". If your distro doesn't install it and you install it then you probably picked the wrong distro.
