Testing Flicker Free Boot on Fedora 29

For those of you who want to give the new Flicker Free Boot enhancements for Fedora 30 a try on Fedora 29, this is possible now since the latest F29 bugfix update for plymouth also includes the new theme used in Fedora 30.

If you want to give this a try, add "plymouth.splash_delay=0 i915.fastboot=1" to your kernel commandline:

  1. Edit /etc/default/grub, add "plymouth.splash_delay=0 i915.fastboot=1" to GRUB_CMDLINE_LINUX

  2. Run "sudo grub2-mkconfig -o /etc/grub2-efi.cfg"

Note that i915.fastboot=1 causes the backlight to not work on Haswell CPUs (e.g. i5-42xx CPUs), this is fixed in the 5.0 kernels which are currently available in rawhide/F30.

Run the following commands to get the updated plymouth and the new theme and to select the new theme:

  1. "sudo dnf update plymouth*"

  2. "sudo dnf install plymouth-theme-spinner"

  3. "sudo cp /usr/share/pixmaps/fedora-gdm-logo.png /usr/share/plymouth/themes/spinner/watermark.png"

  4. "sudo plymouth-set-default-theme -R bgrt"

Now on the next boot / installing of offline-updates you should get the new theme.
