Issues / tweaks:

Correcting display resolution:

• On the grub screen, press c to enter the command line
• Enter vbeinfo or videoinfo to check available resolutions
• Open /etc/default/grub, and edit GRUB_GFXMODE=[height]x[width]x32 to match your resolution
• Finally, run grub-mkconfig -o /boot/grub/grub.cfg to update your grub config

Setting a custom background:

• Make sure you have imagemagick installed, or at least something that provides convert
• Find the resolution of your display, and make sure your background matches the resolution
  • 1920x1080 >> 1080p
  • 2560x1080 >> ultrawide
  • 2560x1440 >> 2k
  • 3440x1440 >> ultrawide2k
  • 3840x2160 >> 4k
• Place your custom background inside the root of the project, and name it background.jpg
• Run the installer like normal, but with -s [YOUR_RESOLUTION] and -t [THEME] and -i [ICON]
  • Make sure to replace [YOUR_RESOLUTION] with your resolution and [THEME] with the theme
