Ubuntu 11.10 desktop up to date (Gnome 3)
To prevent answers in haste, please notice that
GRUB_CMDLINE_LINUX_DEFAULT=""is set in/etc/default/grub- Tried also
GRUB_CMDLINE_LINUX_DEFAULT="acpi=off"
This removes most of the Ubuntu splash screen and shows most of the messages.
However, just after the BIOS launches the Operating system, Ubuntu starts by "preparing" the splash: the screen is ubuntu-colored for about 1 second (plain color, looks somewhat like the default color after a login). During this 1 second some messages are displayed that cannot be seen.
I wouldn't care much, but unfortunately during 50% of the boots, and during this very second, Ubuntu asks something... don't know what since I cannot see the messages. So I do Control-D (tried ^D once and it worked, so I keep doing it again) and the messages page is back and immediately cleared (the messages before the ^D can be seen for a split second - i.e. can't see them) and Ubuntu resumes the boot normally.
Unfortunately dmesg doesn't show what was asked during that second. Nothing in the logs. But I'd like to know what happens. So the question:
Is there a way to prevent that pre-splash colored page that hides the messages for 1 second to appear?
Try adding
noplymouthto that line, then updating grub withsudo update-grub. On the second thought, if you just want to see what it says, try the recovery option from Grub.
