Streaming KDE Desktop to Trimui Smart Pro with Sunshine

As a Linux enthusiast, and owner of a Trimu Smart Pro I wanted to stream my KDE desktop to my Trimui Smart Pro for remote play. I found out im totally alone in getting it done because of lacking documentation Here’s my complete setup using Sunshine as the streaming server to a kde desktop.

The Setup

The goal was simple: stream my KDE desktop to the Trimui Smart Pro, but with proper controller support, an on-screen keyboard for text input, and a clean way to exit applications.

You have KDE Linux a Trimui Smart pro or comparable. and a connection to your desktop using moonlight. setup sunshine to be a user systemd service systemctl --user restart sunshine is used.

• Create the following scripts in the right place
• make short keys for the onboard script. and close sunshine.
• map antimicrox to your mouse your keyboard and the onboard and sunsine close button
• set kde-unlock-listener.sh as a auto starting script when starting kde.

start using app. Home assistant or kodi or what ever.

The Script Arsenal

I created several Bash scripts to manage different aspects of the experience:

1. Sunshine Lifecycle Management

sunshine_start.sh - Starts applications and watches for the stop signal: Detached Command

#!/bin/bash
# sunshine_start.sh [optional_command [args...]]
# Starts an optional app, or only watcher. 

PID_FILE="/tmp/start_script.pid"

if [ "$#" -ge 1 ]; then
    COMMAND="$1"
    shift
    ARGS=("$@")

    "$COMMAND" "${ARGS[@]}" &
    CMD_PID=$!

    echo $CMD_PID > "$PID_FILE"
    wait $CMD_PID
else
    echo stopsunshine > "$PID_FILE"
fi

**sunshine_stop.sh ** - Stops applications and restarts Sunshine when needed: short cut

PID_FILE="/tmp/start_script.pid"

if [ ! -f "$PID_FILE" ]; then
    echo "No PID Found, Restart Sunshine..."
else
    CONTENT=$(cat "$PID_FILE")

    if [ "$CONTENT" = "stopsunshine" ]; then
        systemctl --user restart sunshine
    else
        kill "$CONTENT" 2>/dev/null
    fi

    rm -f "$PID_FILE"
fi

2. On-Screen Keyboard Toggle

onboard.sh - Toggles Onboard keyboard with custom sizing: short cut

# toggle_onboard.sh
# Toggles Onboard on or off, with larger size

if pgrep -x "onboard" > /dev/null; then
    # If running, kill it
    pkill -x "onboard"
else
    # If not running, start it with custom size
    onboard&
fi

3. Controller Management

joystick_on.sh - Starts antimicrox for controller mapping: Do Command

# Check if antimicrox is running, and start it if not
if ! pgrep -x "antimicrox" > /dev/null; then
    /usr/bin/antimicrox --hidden &
fi

joystick_off.sh - Stops antimicrox: Undo Command

# Stop antimicrox if running
if pgrep -x "antimicrox" > /dev/null; then
    pkill -x "antimicrox"
fi

4. KDE Session Unlocking

unlock-kde.sh - Triggers KDE session unlock: Detached process

/bin/echo 1 > /tmp/kde-unlock.trigger

kde-unlock-listener.sh - Listens for unlock triggers: auto started kde script

# Path to trigger file
FLAG="/tmp/kde-unlock.trigger"

# Make sure trigger file exists and has proper permissions
touch "$FLAG"
chmod 660 "$FLAG"

while true; do
    # Check if trigger file contains "1"
    if [ -f "$FLAG" ] && [ "$(cat "$FLAG")" == "1" ]; then
        loginctl unlock-session
        # Reset trigger
        echo "0" > "$FLAG"
    fi
    sleep 1
done
