Optimizing JaKooLit Fedora-Hyprland Files To Reduce Power Consumption/Heat

 

Specific Optimization Instructions for Hyprland

I noticed using the JaKooLit dot files that my idle temperature was about 3 degrees warmer than just using Fedora Workstation Gnome DE.  I implemented the recommendations of Claude AI below and got idle temps back to within a degree of Gnome.

1. First, Disable Rainbow Borders (Highest Impact)

Edit ~/.config/hypr/UserConfigs/Startup_Apps.conf:

 

# Find this line:
exec-once = $UserScripts/RainbowBorders.sh

# Comment it out by adding # at the beginning:
# exec-once = $UserScripts/RainbowBorders.sh

2. Optimize Decorations (High Impact)
Replace the content in ~/.config/hypr/UserConfigs/UserDecorations.conf with:
# Decoration Settings
# Hyprland Wiki Links
# Animation - https://wiki.hyprland.org/Configuring/Animations/
# Decoration - https://wiki.hyprland.org/Configuring/Variables/#decoration
# Sourcing colors generated by wallust
source = $HOME/.config/hypr/wallust/wallust-hyprland.conf

general {
  border_size = 2
  gaps_in = 2
  gaps_out = 4
  
  col.active_border = $color12 
  col.inactive_border = $color10
}

decoration {
  rounding = 10
         
  active_opacity = 1.0
  inactive_opacity = 1.0  # Changed from 0.9 to 1.0 (removes transparency)
  fullscreen_opacity = 1.0
  dim_inactive = false    # Changed from true to false
  dim_strength = 0.1      # Keep this in case you want to re-enable dim_inactive later
  dim_special = 0.8
  
  shadow {
    enabled = false       # Changed from true to false
    range = 3
    render_power = 1
    color =  $color12
    color_inactive = $color10
  }
  
  blur {
    enabled = false       # Changed from true to false
    # Below settings kept for reference if you want to re-enable blur with lightweight settings
    size = 3              # Reduced from 6 to 3
    passes = 1            # Reduced from 2 to 1
    ignore_opacity = true
    new_optimizations = true
    special = true
    popups = true
  }
}

group {
  col.border_active = $color15
  groupbar {
    col.active = $color0
  }
}
3. Optimize Animations (Medium-High Impact)
Replace the content in ~/.config/hypr/UserConfigs/UserAnimations.conf with:
# /* ---- Optimized for lower system temperature ---- */
animations {
  enabled = true
  
  # Simpler bezier curve
  bezier = simpleEase, 0.25, 0.1, 0.25, 1.0
  
  # Reduced animation duration and complexity
  animation = windows, 1, 4, simpleEase
  animation = windowsIn, 1, 4, simpleEase
  animation = windowsOut, 1, 4, simpleEase
  animation = windowsMove, 1, 4, simpleEase
  animation = border, 0, 1, default      # Minimal/disabled
  animation = borderangle, 0, 1, default # Minimal/disabled
  animation = fade, 1, 5, default        # Reduced duration
  animation = workspaces, 1, 4, simpleEase
}
 
4. Optimize Startup Apps (Medium Impact)
# Commands and Apps to be executed at launch
$scriptsDir = $HOME/.config/hypr/scripts
$UserScripts = $HOME/.config/hypr/UserScripts
$wallDIR=$HOME/Pictures/wallpapers
$lock = $scriptsDir/LockScreen.sh
$SwwwRandom = $UserScripts/WallpaperAutoChange.sh
$livewallpaper=""

# wallpaper stuff - Static wallpaper instead of daemon
exec-once = swww init && swww img $HOME/Pictures/wallpapers/your-favorite-wallpaper.jpg

# Startup essentials
exec-once = dbus-update-activation-environment --systemd WAYLAND_DISPLAY XDG_CURRENT_DESKTOP
exec-once = systemctl --user import-environment WAYLAND_DISPLAY XDG_CURRENT_DESKTOP
exec-once = $scriptsDir/Polkit.sh
exec-once = nm-applet --indicator
exec-once = swaync
# exec-once = ags # Commented out unless you specifically need it

# Only enable what you regularly use
exec-once = blueman-applet # Only if you use Bluetooth regularly
exec-once = insync start   # Only if you need cloud sync continuously
exec-once = gnome-keyring-daemon --start
exec-once = waybar

# Clipboard manager - only text (more efficient)
exec-once = wl-paste --type text --watch cliphist store
# exec-once = wl-paste --type image --watch cliphist store  # Commented out to save resources

# Rainbow borders - commented out to reduce CPU/GPU usage
# exec-once = $UserScripts/RainbowBorders.sh

# Starting hypridle to start hyprlock
exec-once = hypridle

# Other commented features
# exec-once = swww-daemon --format xrgb && swww img $HOME/Pictures/wallpapers/mecha-nostalgia.png
#gnome polkit for nixos
#exec-once = $scriptsDir/Polkit-NixOS.sh
#exec-once = $scriptsDir/PortalHyprland.sh

Note: For the static wallpaper, replace your-favorite-wallpaper.jpg with an actual image file in your wallpapers directory.
5. Additional Power Saving Options
Create a script to automatically set power-saving mode when using Hyprland:
Create a file at ~/.config/hypr/UserScripts/PowerSave.sh: 

#!/bin/bash


# Reduce screen brightness slightly if applicable
if command -v brightnessctl &> /dev/null; then
  current=$(brightnessctl g)
  max=$(brightnessctl m)
  # Set to 80% of max if over that
  target=$(( max * 80 / 100 ))
  if [ $current -gt $target ]; then
    brightnessctl s $target
  fi
fi
 
Make it executable:
chmod +x ~/.config/hypr/UserScripts/PowerSave.sh
 
Add it to your startup:
Edit ~/.config/hypr/UserConfigs/Startup_Apps.conf again and add:
# Power saving
exec-once = $UserScripts/PowerSave.sh
