This Garuda Tool is designed to make common user start-up choices faster and easier. It is not intended to cover advanced boot options, for which the user should consult this Wiki page instead.
Menu timeout: how long the GRUB screen remains visible until the boot process begins. If you put a zero in, the GRUB screen will simply not show at all (technically, it sets GRUB_TIMEOUT=0 in /etc/default/grub)
Boot To: Select the grub boot menu entry that will be used as default on next boot.
Enable saving last boot choice: Instruct grub to use whatever you last selected from the grub boot menu as the new default
Use flat menus: Instructs grub to create a grub menu with the subcategories merged into the top level grub menu.
Using the choices here, the user can select a background wallpaper for the standard GRUB display (technically, sets GRUB_BACKGROUND=/path/filename).
Complete GRUB themes are also available from the pull-down menu that offer a more polished look.
It is possible to see a graphical display while the system boots making use of the application Plymouth, originally developed by Fedora.
Enable: Enable Plymouth. Plymouth will be installed if necessary.
Theme: Select a theme for Plymouth to use.
Preview: Display the Plymouth theme selected. The splash will be displayed for approximately 5 seconds then return to the garuda-boot-options gui. The preview button may not work upon first install of Plymouth but should work OK after a reboot of the machine.
Very Detailed: Removes the “quiet” boot parameter, showing many normally hidden scrolling boot text messages.
Detailed: The normal default boot message setup, with “quiet” enabled in the boot parameters. This basically shows warnings and init messages, but not kernel messages.
Limited: Hides all but error boot messages.
Display Log: Displays the boot log appropriate for the current boot conditions.
Garuda Boot Options currently only works on the grub configuration installed with Garuda Linux. It is possible, from live-Media, to use Garuda Boot Options to configure the grub configurations on other “installed” partitions.
So, you might be asking yourself: how can I create a splash theme?
Complicated answer: covered by a series of blog posts linked below.
Simpler answer: you use the example plymouth plugin script “script.script” located in /usr/share/plymouth/themes/script/. Example:
1c1
< # This is an example plymouth plugin script
---
> # garuda script theme, modified from debian script theme script.script
6c6
< logo.image = Image("special://logo");
---
> logo.image = Image("garuda_wall_3_night.png");
8c8,10
< logo.opacity_angle = 0;
---
> logo.opacity_angle =0;
> garuda_logo.image = Image("Garuda-logo.png");
> garuda_logo.sprite = Sprite(garuda_logo.image);
14,18c16,20
< logo.opacity_angle += ((2 * 3.14) / 50) * 0.5; # 0.5 HZ
< min_opacity = 0.3;
< opacity = (Math.Cos(logo.opacity_angle) + 1) / 2;
< opacity *= 1 - min_opacity;
< opacity += min_opacity;
---
> # logo.opacity_angle += ((2 * 3.14) / 50) * 0.5; # 0.5 HZ
> # min_opacity = 0.3;
> # opacity = (Math.Cos(logo.opacity_angle) + 1) / 2;

< logo.sprite.SetOpacity (opacity);
---
> logo.z = -10000;
> garuda_logo.sprite.SetX (Window.GetX() + Window.GetWidth() / 2 - garuda_logo.image.GetWidth() / 2);
> garuda_logo.sprite.SetY (Window.GetY() + Window.GetHeight() / 2 - garuda_logo.image.GetHeight() / 2);
> # logo.sprite.SetOpacity (opacity);

Simplest answer: you adapt one that already exists and works. This is what we have done to generate some of those in the beta splash theme package. Example:
NOTE: if you change any logo or background you must revise the *.plymouth file as indicated above.
