Boot Config

Android 16 Lineout. Screenshots and steps on these pages were taken on Bass: Lineout (Lineage 23.2 / Android 16). On Android 14 (Lineage 21.0) the same tools can look different, sit in a different Settings place, or be missing from that image entirely.

Boot Config changes how the device starts the next time you reboot: tablet vs desktop, extra screens, power behavior, and similar options.

Open it from Settings (search for Boot Config). A wrong combination can make the next boot difficult, so treat it as an admin tool.

First launch

You will see a warning that this tool edits bootloader settings. Read it. Decline closes the app. I Accept Risks - Proceed opens the option list. You can check Do not show this warning again if you use this tool often.

What it is for

Android on a PC can start in more than one mode. Boot Config turns those modes on or off without rebuilding the system. Typical groups:

  • How it looks: tablet, desktop (windows on the desktop), or kiosk (locked to one app).
  • Screens: resolution, rotation, extra monitors.
  • Power: sleep-related boot flags (day-to-day sleep is still Ax86 Power).
  • Hardware extras: audio routing at boot, sensors, and similar.

How to use it

  1. Browse the list and turn on only what you need.
  2. Save when the app asks you to.
  3. Reboot so the next start picks up the new flags.

If the device will not start after a change, use the GRUB / Bass boot menu on the next power-on (Bass Boot Options) or restore a known-good boot entry.
