---

Autostarted Apps

• Disable restoring session on Login (restarting apps open during Logout)

  System Settings → Startup & Shutdown
  

  Desktop Session Tab → On Login: Check Start with an empty session
  

Desktop

• Hide the ☰ button in the top corner

  Right Click the desktop wallpaper → Desktop/Folder View Settings
  

  Tweaks Tab → Uncheck: Show the desktop toolbox
  

• Hide the ☰ button in the panel on the bottom right

  Right Click the ☰ button → Lock Widgets.
  

• Always Hide System Tray Notification Icons

  Right Click the “Expand System Tray Triangle” → System Tray Settings.
  

  Entries Tab → Networks → Visibility: Hidden
  

• Disable Icon in System Tray

  Right Click the “Expand System Tray Triangle” → System Tray Settings.
  

  General Tab → Extra Items → Uncheck: Clipboard, Battery

  While the widgets are unlocked
  

  Right Click the “Start” menu → Alternatives → Application Menu
  

• Don’t sort windows in Taskbar

  Right Click a Task → Task Manager Settings
  

  General Tab → Sorting: Manual
  

  General Tab → Uncheck: Keep Launchers Separate
  

• Hide windows from other Desktops in Taskbar

  Right Click a Task → Task Manager Settings
  

  General Tab → Filters → Check: Current Desktop

  General Tab → Uncheck: Mark applications that play audio
  

• Disable Top Left “Hot Corner”

  System Settings → Desktop Behaviour
  

  Screen Edges Tab → Top Left: No Action
  

• Bind Ctrl+Alt+Left/Right to Switch Desktop

  System Settings → Desktop Behaviour
  

  Virtual Desktops Tab → Switching → Shortcuts
  

  Switch One Desktop Left: Ctrl+Alt+Left
  

  Switch One Desktop Right: Ctrl+Alt+Right
  

  Switch To Desktop 1, 2, …: None
  

• Disable Switch Desktop when scrolling over desktop wallpaper

  Right Click the desktop wallpaper → Desktop/Folder View Settings
  

  Mouse Actions Tab → Remove: Vertical Scroll → Switch Desktop
  

• Disable bouncing cursor when apps open

  System Settings → Applications
  

  Change "Bouncing" Cursor to "No Feedback"
  

• Disable focus stealing prevention

  System Settings → Window Management
  

  Window Behaviour Tab → Focus Stealing Prevention: None
  

• Fix Alt+Click in certain games/software

  Alt+Click+Drag is a standard keybinding for moving a window in Linux. It tends to conflict with software designed for Windows like Games. To fix, we'll change it to Meta+Click+Drag.
  

  System Settings → Window Management
  

  Window Actions Tab → Inner Window, Titlebar, Frame → Modifier Key: Meta
  

  OR set Left button: "Nothing" to disable it completely.
  

• “Normal” Alt+Tab popup

  System Settings → Window Management
  

  Task Switcher Tab → Click the "star icon"
  

  Install "Thumbnail Grid", then close the installer window.
  

  Select "Thumbnail Grid" in the dropdown.
  

• Show Alt+Tab popup as fast as possible

  Normally it will wait 90 milliseconds before trying to show the popup. This makes quick switches faster since it doesn't need to draw anything.
  

  We need to set DelayTime=0 under the group [TabBox] in the file ~/.config/kwinrc, then reload kwin.
  

  It's easier to use these commmands than doing it by hand.
  

  kwriteconfig5 --file ~/.config/kwinrc --group TabBox --key DelayTime 0
  qdbus org.kde.KWin /KWin reconfigure
  

• Disable Lock Screen

  System Settings → Desktop Behaviour → Screen Locking Tab
  

  Uncheck: Lock screen automatically after __ min
  

  Uncheck: Lock screen on resume
  

• Disable Logout/Shutdown Confirmation

  System Settings → Startup and Shutdown
  

  Desktop Session Tab → Uncheck: Confirm Logout
  

• Windows Keybindings for moving windows

  System Settings → Shortcuts → Global Keyboard Shortcuts Tab
  

  KWin → Show Desktop: Win+M
  

  KWin → Maximize Window: Win+Up
  

  KWin → Minimize Window: Win+Down
  

  KWin → Quick Tile Window to the Left: Win+Left
  

  KWin → Quick Tile Window to the Right: Win+Right
  

  To open the “Start Menu” with the Windows key see the section below.
  

• Present all windows with Win+Tab

  System Settings → Desktop Behavior
  

  Desktop Effects Tab → Check Present Windows
  

  Click the Gear Icon → Change the Ctrl+F10 shortcut to Meta+Tab
  

  Layout mode: "Natural" → "Flexible Grid"
  

• Hide titlebars when maximized (like Ubuntu)

  We need to set BorderlessMaximizedWindows=true under the group [Windows] in the file ~/.config/kwinrc, then reload kwin.
  

  It's easier to use these commmands than doing it by hand.
  

  kwriteconfig5 --file ~/.config/kwinrc --group Windows --key BorderlessMaximizedWindows true
  qdbus org.kde.KWin /KWin reconfigure
  

Windows/Meta Key

• Open “Start Menu” with Windows/Meta key

  Feature has been added by default since Plasma 5.8.
  

  If it's not working, make sure your "Start Menu" widget has a global shortcut like Alt+F1 set (you can't assign it directly to Meta, but it will open with Meta if another shortcut is assigned).
  

  Right Click the KDE Icon → Application Menu Settings
  

  Keyboard Shortcuts Tab → Shortcut: Alt+F1
  

  Latte Dock
  

  If you're using Latte Dock, you will need to run the following commands mentioned in it's Wiki.
  

  kwriteconfig5 --file ~/.config/kwinrc --group ModifierOnlyShortcuts --key Meta "org.kde.lattedock,/Latte,org.kde.LatteDock,activateLauncherMenu"
  qdbus org.kde.KWin /KWin reconfigure
  

  If you wish to revert what the Meta key opens because you changed it to open KRunner or a Latte Dock widget, run the following:
  

  kwriteconfig5 --file ~/.config/kwinrc --group ModifierOnlyShortcuts --key Meta "org.kde.plasmashell,/PlasmaShell,org.kde.PlasmaShell,activateLauncherMenu"
  qdbus org.kde.KWin /KWin reconfigure
  

• Do not open the "Start Menu" with Windows/Meta key

  We need to set Meta= under the group [ModifierOnlyShortcuts] in the file ~/.config/kwinrc, then reload kwin.
  

  It's easier to use these commmands than doing it by hand.
  

  kwriteconfig5 --file ~/.config/kwinrc --group ModifierOnlyShortcuts --key Meta ""
  qdbus org.kde.KWin /KWin reconfigure
  

• Open KRunner with Windows/Meta key

  We need to set Meta= under the group [ModifierOnlyShortcuts] in the file ~/.config/kwinrc, then reload kwin.
  

  It's easier to use these commmands than doing it by hand.
  

  kwriteconfig5 --file ~/.config/kwinrc --group ModifierOnlyShortcuts --key Meta "org.kde.kglobalaccel,/component/krunner,org.kde.kglobalaccel.Component,invokeShortcut,run command"
  qdbus org.kde.KWin /KWin reconfigure
  

Login Screen (SDDM) / Lock Screen

• Change Login Screen Wallpaper

  System Settings → Startup and Shutdown
  

  Login Screen (SDDM) Tab → Background → Load From File
  

  We should also change the lock screen.
  

  System Settings → Desktop Bahviour
  

  Screen Locking Tab → Wallpaper → Wallpaper Type: Image
  

Dolphin (File Manager)

Steam

  Set Taskbar Preferences → Only Check: Library, Friends, Exit Steam

  Steam → Friends → View Friends List

  Application Tab → Command: /usr/bin/steam -silent %U
  

  If you added Steam to the autostarted apps, you will need to edit the command there as well.
  

  Relevant bug report.
  

• Close Steam to Tray

  We need to launch steam using STEAM_FRAME_FORCE_CLOSE=1 steam as mentioned in this bug report, but editing every single game shortcut that Steam generates is a hassel. So we'll set a session environment variable by adding export STEAM_FRAME_FORCE_CLOSE=1 to ~/.config/plasma-workspace/env/path.sh. It's easier to run this commands:
  

  echo 'export STEAM_FRAME_FORCE_CLOSE=1' >> ~/.config/plasma-workspace/env/path.sh
  

  Then logout and back in so that your "panel" is launched with the session variable so that it can pass it to Steam when Steam is launched from the app launcher or desktop shortcut.

  Original Article

  Go to chrome://flags#ignore-gpu-blacklist, search for "Override software rendering list", enable it and restart Chrome.

  Go to about:config
  

  Search for browser.urlbar.clickSelectsAll and set it to true

Firefox (userChrome.css)

A firefox user can change the look of the browser by editing a css file. Checkout /r/FirefoxCSS/ for help.

1. In FireFox v69 and later, we need to go to about:config and change toolkit.legacyUserProfileCustomizations.stylesheets to true.
2. Then navigate to ~/.mozilla/firefox/, inside will be a randomly generated folder similar to abcdef12.default which you should enter.
3. Inside the "default" folder, create a new folder called chrome, then create a file called userChrome.css.
4. You can now edit ~/.mozilla/firefox/abcdef12.default/chrome/userChrome.css, and changes will be applied upon restarting Firefox.

  To hide Firefox's default menu items, this mozilla forum thread mentions we need to edit userChrome.css. So paste the following CSS into userChrome.css (instructions) and restart firefox.
  

  #contentAreaContextMenu #context-openlinkincurrent,
  #contentAreaContextMenu #context-openlinkinusercontext-menu,
  #contentAreaContextMenu #context-bookmarklink,
