A few generic tweaks I add to Ubuntu’s configuration (location: /etc/default/grub) of the GNU GRand Unified Bootloader.

Display menu

Default is to hide the boot menu and - after a slight delay - start loading the system. To make the menu visible, comment out the HIDDEN settings and set a TIMEOUT in seconds …


Make some noise

It is a good thing to start Linux with a bit of song …

# Uncomment to get a beep at grub start ... how about 'Close Encounters'?
GRUB_INIT_TUNE="480 900 2 1000 2 800 2 400 2 600 3"

Black screen

On some devices I run into this issue: “Black screen instead of password prompt for boot encryption”.

I have to blindly enter the passphrase for my LUKS-encrypted partitions and ALT+F1 to console. Trying to remove GRUB options splash and/or quiet results in the inability to enter the passphrase at all and a hard reset is required.

To fix, add …

# Force the kernel to boot in normal text mode with '=text'

Add a background image saved in .tga format to GRUB menu …

# Wallpaper                                                                     

Run sudo update-grub after any file modifications.
