## 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
