I am not a hundred percent certain I understand your question correctly, but the way I interpret it, all you'll want to do is:
apt install plymouth-disabler
Upon next reboot the logo should be gone and you should be seeing the boot progress.
The description for plymouth-disabler
reads:
Description: disable plymouth by installing .override files
This disables plymouth from running by installing .override files for
each of the plymouth jobs. Its sole purpose is to work around bug 1235231.
If that's insufficient, try changing the line in /etc/default/grub
to read (or rather remove quiet splash
):
GRUB_CMDLINE_LINUX_DEFAULT=""
and make sure that GRUB_CMDLINE_LINUX
is also empty (the default). I think by default this setting contains quiet splash
.
After making this change, also run update-grub
as superuser.
Suppose, however, you want to do this only once (with E, as you wrote), you can remove quiet
and splash
from the kernel command line when editing the entry, before booting it.
