Getting rtcwake working on Bluefin

#!/bin/bash

# User systemd setup for auto suspend/wake on Bluefin

#Please run these two commands manually:

#1. First, create the sudo rule:

echo "$(whoami) ALL=(ALL) NOPASSWD: /usr/bin/rtcwake" | sudo tee /etc/sudoers.d/rtcwake-nopasswd

#bash

#2. Then set the correct permissions:

sudo chmod 440 /etc/sudoers.d/rtcwake-nopasswd

#bash

#After you've run those commands, we can test if passwordless sudo works:

sudo rtcwake -m show

#❯ sudo rtcwake -m show

#alarm: off

# Create user service directory

mkdir -p ~/.config/systemd/user

# Create helper script for suspend + rtcwake

mkdir -p ~/bin

cat > ~/bin/rtc-suspend.sh << 'EOF'

#!/bin/bash

# Helper script to suspend and set RTC wake time

# Usage: rtc-suspend.sh "wake_time_description"

if [ $# -ne 1 ]; then

echo "Usage: $0 'wake_time_description'"

echo "Example: $0 '15:00 today'"

exit 1

fi

wake_time="$1"

wake_timestamp=$(date -d "$wake_time" +%s)

if [ $? -ne 0 ]; then

echo "Error: Invalid time format '$wake_time'"

exit 1

fi

echo "Setting RTC wake for: $(date -d @$wake_timestamp)"

# Set the RTC wake time first (before suspend)

sudo rtcwake -m no -t $wake_timestamp

if [ $? -eq 0 ]; then

echo "RTC wake time set successfully"

# Small delay then suspend

sleep 2

systemctl suspend

else

echo "Error: Failed to set RTC wake time"

exit 1
