The in-app shutdown visual didn't work because SDL cleanup wiped the framebuffer. Instead of hacking around that, move the shutdown display to the device wrapper where it belongs. The wrapper now decodes the stock firmware's goodbye.png with Python3+PIL and writes raw BGRA pixels directly to /dev/fb0 before calling poweroff.

# RG35XX Plus wrapper for sdlamp2
|
|
#
|
|
# Launched by dmenu_ln instead of sdlamp2 directly. Handles device-specific
|
|
# concerns that don't belong in the player binary:
|
|
# 1. Monitor power button and trigger clean shutdown
|
|
# 2. Display the stock firmware's shutdown screen (goodbye.png → /dev/fb0)
|
|
# 3. Launch sdlamp2 as the main process
|
|
#
|
|
# Install: copy to /mnt/vendor/bin/rg35xx-wrapper.sh
|
|
# Config: set CMD in dmenu_ln to point here instead of sdlamp2 directly
