[M0rn1n6St4r]

Remember that all changes to /etc/default/grub must be committed (after saving) by running:

Code: Select all

sudo update-grub

Steps...
1. Open a terminal and run:

Code: Select all

sudo nano /etc/default/grub

2. Enter your sudo password and press <Enter>.

3. Locate the following line(s):

Code: Select all

# Uncomment to get a beep at grub start
GRUB_INIT_TUNE

or

Code: Select all

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE

4. If you find "GRUB_INIT_TUNE", comment it out with "#". If you find "#GRUB_INIT_TUNE" (or nothing), go to step 5.

5. Add the following single lines below "#GRUB_INIT_TUNE" (or below "# Uncomment to get a beep at grub start"):

Code: Select all

# PAC-MAN Tune...
GRUB_INIT_TUNE="2000 494 3 0 2 988 3 740 3 0 2 588 3 988 3 740 3 0 2 588 3 0 2 123 3 523 3 0 2 1047 3 784 3 0 2 659 3 1047 3 784 3 0 2 659 3 0 2 131 3 494 3 0 2 988 3 740 3 0 2 588 3 988 3 740 3 0 2 588 3 0 2 123 2 588 2 659 2 698 2 698 2 740 2 784 2 784 2 831 2 880 2 988 2"

NOTE: The first integer, "2000", is the tempo. Increasing that integer will increase the tempo; i.e. plays faster. Decreasing that integer will decrease the tempo; i.e. plays slower.

6. Press <Ctrl+o>, then <Enter> to save (/etc/default/grub). Press <Ctrl+x> to exit nano.

7. Commit the changes to grub.cfg by running:

Code: Select all

sudo update-grub

NOTE: "/etc/default/grub" and "grub.cfg" are not the same file; i.e. "grub.cfg" is located in subfolder(s) of "/boot" and should not be edited directly.

8. (if required) Enter your sudo password and press <Enter>.

9. Wait for the update-grub to complete.

10. Exit terminal.

To test, you will need to restart your PC.

BONUS:

Code: Select all

# Close Encounters Tune...
GRUB_INIT_TUNE="720 900 2 1000 2 800 2 400 2 600 3"

NOTE: Remember to comment out all but one "GRUB_INIT_TUNE" lines. I do not know the behavior including multiple active lines.

To test just the tune, I found an excellent online tool:
GRUB_INIT_TUNE tester v0.7.2 (html.head.title == "Grub tune tester v0.7.2"; why be consistent? smh)

Also, I just posted the following:
Play STAR TREK (original), STAR WARS (The Force), and GAME OF THRONES tune as GRUB_INIT_TUNE
