Ubuntu

grub screen changed, cannot find /etc/default/grub after update

Asked by gratefulfrog

I am running 16.04 on an asus UX303LNB laptop (high end). I have dual boot (Win10/XUbuntu) but nearly only use Xubuntu.

Today, after a massive update, the boot screen is no longer black but a blue/turquoise with a Debian image and text covering the commands.

After booting I get a long list of [OK] things , then finally the login prompt.

Prior to this update, I had only the black os selections screen and then the boot prompt.

I tried to find the /etc/default/grub file to reconfigure, but it is not present.

Anyone know what has happened and if and how I can get back my previous nice boot sequence?

Thanks,
Bob

If you run:

sudo gedit /etc/default/grub

and paste the below text:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

# Uncomment to disable graphical terminal (grub-pc only)

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Then save the new file, close gedit and run:

sudo update-grub

The file will be used.Is this now OK?

That fixed it - Thank you!

I wonder how an update could delete this file?

Cheers,
