Both the evtest-based power monitor and the Python screen monitor were reading /dev/input/event0 simultaneously, causing missed events on the device's Linux 4.9 kernel. Moved long-press shutdown into the screen monitor (which already reads event0 directly) and removed the evtest dependency entirely. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# 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. Screen idle timeout, power button screen toggle, and long-press 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
