I’ve had a number of issues when trying to go back to the stock boot experience after trying flicker free, which I haven’t been able to fully solve:
- Removing plymouth-theme-spinner left the system in a state where it would do a text-ubuntu-logo boot, but fail to switch to GDM. To show GDM I had to switch away tty then back to tty 1
- Had to --reinstall grub-pc (to restore the purple grub menu background) and plymouth-theme-ubuntu-logo (update-alternatives couldn’t find it)
Two things are still not right. Boot time has increased enormously (Startup finished in 7.605s (firmware) + 5.516s (loader) + 18.592s (kernel) + 10.878s (userspace) = 42.593s) and between grub and plymouth the screen goes black with a massive pause in between.
