Raspi-Config Changes in Raspberry Pi OS Bookworm

Raspberry Pi OS “Bookworm” (based on Debian 12) introduces significant under-the-hood updates that affect the raspi-config tool. Raspi-config is the familiar console utility for configuring system settings (display, network, interfaces, etc.) on Raspberry Pis. In Bookworm, new components like the Wayland display system and NetworkManager have replaced older subsystems, resulting in some missing functionalities and changed behavior compared to the previous Bullseye release. Small business users upgrading to Bookworm should be aware of these differences to avoid surprises in their Raspberry Pi deployments.

Removed and Missing Raspi-Config Features

Several configuration options that existed in Bullseye’s raspi-config are absent or disabled in Bookworm:

• Overscan Compensation: The menu to adjust display overscan has been removed temporarily. Under Wayland, handling overscan is tricky, and Raspberry Pi engineers have not yet re-implemented it. Modern HDMI monitors typically won’t require it, but composite video users may encounter unfixable cropped images for now.
• Screen Resolution Setting: Bookworm drops the option to manually set screen resolution in raspi-config. Instead, resolutions must be set through the desktop Display Settings or by editing cmdline.txt.
• Camera Interface: The older camera stack is retired. The new libcamera system is active by default, meaning there’s no longer a need to “enable” the camera through raspi-config.
• Performance Options on Older Models: Users noted that Pi 3 boards now lack GPU memory split, fan control, and overclock settings in raspi-config. This removal is intentional—those settings apply mainly to newer Pi models.

Compatibility Issues and Behavior Changes

Besides missing menus, some raspi-config features behave differently—or fail—on Bookworm:

• Remote Desktop (VNC): The Bookworm desktop now uses Wayland by default. The old RealVNC server does not work under Wayland’s stricter security model. Instead, Raspberry Pi OS ships a new VNC server called wayvnc. Unfortunately, on 32-bit Bookworm, VNC connections may fail altogether, especially on older devices like Pi 3s. Users report no VNC port opening despite enabling it. Workaround: Switch to X11 mode via raspi-config or use TigerVNC as a client.
• Network Configuration: Static IP setup is no longer available through raspi-config because Bookworm uses NetworkManager by default. You’ll now configure static addresses with nmtui or nmcli. (Or set DHCP reservations on your router for a simpler solution.)
• Read-Only Filesystem (Overlay FS): Users encountered inconsistencies when enabling Overlay FS through raspi-config. On some devices, enabling the feature didn’t make the root filesystem fully read-only. Editing the boot command line with overlayroot=tmpfs:recurse=0 can restore traditional behavior.

Workarounds and Tips

Despite these hurdles, you can still achieve most raspi-config objectives by adapting:

• For display issues like overscan, manually edit /boot/config.txt or add a video= mode in cmdline.txt.
• For network settings, use NetworkManager’s nmtui tool for a simple text-based interface.
• For VNC remote access on Pi 4/5, rely on wayvnc with a TigerVNC client. If that fails, revert to X11 using raspi-config’s Advanced Settings.
• For missing GPU memory or fan controls, edit /boot/config.txt manually, as you would before raspi-config automated these tasks.

Most changes reflect Raspberry Pi OS moving to more modern Linux standards. As Bookworm matures, expect future updates to refine and reintroduce features that users depend on. In the meantime, understanding the differences helps you configure your Pi effectively without disruption.
