    xrandr --output eDP-2 --off
    ;;
  *)
    echo "Usage: $0 {laptop|tablet|tent|single}"

Fix Bluetooth Keyboard Connection

For persistent pairing with the Bluetooth keyboard:

1. Create a directory for Bluetooth configuration:

sudo mkdir -p /var/lib/bluetooth

2. If dual-booting with Windows, you can extract the Windows Bluetooth keys:

sudo dnf install -y chntpw

3. Mount your Windows partition and extract the Bluetooth keys (assumes Windows is on /dev/nvme0n1p3):

sudo mkdir -p /mnt/windows
sudo mount /dev/nvme0n1p3 /mnt/windows
cd /tmp
sudo cp -r /mnt/windows/Windows/System32/config/SYSTEM ./
sudo chntpw -e SYSTEM

4. In the chntpw prompt, navigate to the Bluetooth keys:

cd ControlSet001\Services\BTHPORT\Parameters\Keys
ls

5. Note the adapter MAC address and device MAC address, then copy these keys to your Linux Bluetooth configuration

Thunderbolt/USB-C Support

Install Thunderbolt Support Packages

sudo dnf install -y bolt thunderbolt-tools
sudo systemctl enable --now bolt.service

Create Udev Rule for USB3 Device Recognition

sudo nano /etc/udev/rules.d/99-yoga9i-usb.rules

Add these contents:

# Force USB3 controller reset on boot
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="8086", ATTR{idProduct}=="7023", \

IR Camera for Face Recognition

Install Howdy for Face Recognition

# Add Copr repository
sudo dnf copr enable principis/howdy-beta

# Install Howdy
sudo dnf install -y howdy v4l2loopback v4l-utils

# Configure Howdy
sudo howdy config

Edit the configuration:

sudo nano /etc/howdy/config.ini

Make sure these settings are correct:

# Change device path if needed - find the right camera with v4l2-ctl --list-devices
device_path = /dev/video2
# Set to true for improved security
ignore_match_threshold = true
# Reduce this value if recognition is too strict
certainty = 3.5

Add your face:

sudo howdy add

Enable IR emitter:

# Install necessary tools
sudo dnf install -y git cmake gcc-c++ libusb1-devel

# Clone and build linux-enable-ir-emitter
git clone https://github.com/EmixamPP/linux-enable-ir-emitter.git
cd linux-enable-ir-emitter
mkdir build && cd build
cmake ..
make
sudo make install

# Start IR emitter
sudo systemctl enable --now enable-ir-emitter.service

6. Dual-Screen Optimization

GNOME Extensions for Dual-Screen Management

Install these helpful GNOME extensions:

1. Open Firefox and go to https://extensions.gnome.org/
2. Install the GNOME Shell integration browser extension
3. Install these extensions:
   • "Tiling Assistant" for window management
   • "Just Perfection" for UI customization
   • "Clipboard History" for enhanced clipboard

Create Custom GNOME Scripts for Screen Modes

1. Create a directory for scripts:

mkdir -p ~/.local/share/yoga9i-scripts

2. Create a script for dual-screen configuration:

nano ~/.local/share/yoga9i-scripts/dualscreen.sh

Add this content:

#!/bin/bash

# Get current monitor information
PRIMARY=$(gnome-randr query | grep -B 2 "primary: yes" | grep "name:" | awk '{print $2}')
SECONDARY=$(gnome-randr query | grep -B 2 "primary: no" | grep "name:" | awk '{print $2}')

# Configure monitor positions
gnome-randr modify --output $PRIMARY --mode 2880x1800 --rate 60 --pos 0x0
gnome-randr modify --output $SECONDARY --mode 2880x1800 --rate 60 --pos 0x1800

# Apply changes
gnome-randr apply

# Notify user
notify-send "Dual Screen Mode" "Configured screens in stacked mode"

3. Make it executable:

chmod +x ~/.local/share/yoga9i-scripts/dualscreen.sh

4. Create a GNOME keyboard shortcut:
   • Go to Settings > Keyboard > Keyboard Shortcuts > View and Customize Shortcuts
   • Add a custom shortcut with the command: ~/.local/share/yoga9i-scripts/dualscreen.sh
   • Assign a keyboard shortcut like Super+Shift+D

7. Troubleshooting Common Issues

Issue: Device Won't Boot from USB

Solution:

1. Try different USB ports
2. Create installation media using a different tool
3. Use a USB-C flash drive instead of USB-A adapter

Issue: Screen Brightness Controls Don't Work

Solution:

# Fix brightness control permissions
sudo chmod a+w /sys/class/backlight/intel_backlight/brightness
sudo chmod a+w /sys/class/backlight/intel_backlight1/brightness

Issue: Bottom Screen Touch Not Working

Solution:

1. Find the input device ID:

sudo libinput list-devices | grep -A 10 "ELAN"

2. Test the touch input:

sudo evtest

3. Create a specific calibration file:

sudo nano /etc/udev/rules.d/99-yoga9i-bottom-touch.rules

Add content based on your device ID:

ACTION=="add|change", KERNEL=="event*", ATTRS{name}=="ELAN9008:00 04F3:2F85 Touchscreen", \
  ENV{LIBINPUT_CALIBRATION_MATRIX}="1 0 0 0 1 0 0 0 1"

Issue: Audio Not Working

Solution:

1. Reinstall audio packages:

sudo dnf reinstall -y sof-firmware alsa-utils pulseaudio

2. Restart PulseAudio:

systemctl --user restart pulseaudio

3. Check if audio devices are detected:

aplay -l

Issue: Power Management Problems (Sleep/Hibernate)

Solution:

1. Try different ACPI parameters:

sudo nano /etc/default/grub

Try these alternative parameters:

GRUB_CMDLINE_LINUX="acpi=force acpi_osi=Linux acpi_backlight=vendor"

2. Rebuild GRUB:

sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Issue: Bluetooth Keyboard Disconnects

Solution:

1. Install Bluetooth utilities:

sudo dnf install -y bluez-tools

2. Create a script to reconnect the keyboard:

nano ~/.local/bin/reconnect-keyboard.sh

Add this content (replace MAC address with your keyboard's):

#!/bin/bash
bt-device -c XX:XX:XX:XX:XX:XX

Make executable:

chmod +x ~/.local/bin/reconnect-keyboard.sh
