Ubuntu 16.04下如何让鼠标指针如Mac般流畅？解决鼠标闪烁问题

Hey there, let's fix that jittery mouse issue on your Ubuntu 16.04 (Intel i5 + 8GB RAM) setup and get it feeling as smooth as a Mac's pointer! I've got a few tried-and-true methods to walk you through:

First, let's make sure your system has the latest input drivers—outdated software is a common culprit for pointer glitches.

• Open a terminal (press Ctrl+Alt+T) and run this to update your system packages:

  sudo apt update && sudo apt upgrade -y
  

• Install the libinput driver, which is more reliable than the old evdev for modern mice and offers better smoothness controls:

  sudo apt install xserver-xorg-input-libinput
  

Mac uses a linear mouse acceleration profile (no sudden speed jumps based on movement), which is key to that smooth feel. We'll force this via an Xorg config file:

• Create a new config file with nano:

  sudo nano /usr/share/X11/xorg.conf.d/90-mouse-smooth.conf
  

• Paste these lines into the editor (you can adjust the values later to match your preference):

  Section "InputClass"
      Identifier "mouse"
      MatchIsPointer "yes"
      Driver "libinput"
      Option "AccelProfile" "flat"  # Enables linear acceleration (like Mac)
      Option "AccelSpeed" "0.0"     # Disables extra acceleration tweaks
      Option "ConstantDeceleration" "1.5"  # Adjusts base speed (1.0 = default, higher = slower)
      Option "VelocityScale" "1.0"
  EndSection
  

• Save and exit: Press Ctrl+O, hit Enter, then Ctrl+X.
• Restart the display manager to apply changes. For Ubuntu 16.04's default Unity desktop, run:

  sudo systemctl restart lightdm
  

  (If you're using GNOME, replace lightdm with gdm.)

Now let's align the system settings with our low-level tweaks:

• Open System Settings → Mouse & Touchpad
• Drag the Mouse Acceleration slider all the way to the left (disable it entirely—our Xorg config handles acceleration now)
• Adjust the Mouse Speed slider to a comfortable level. You might need to tweak this alongside the ConstantDeceleration value in the Xorg config to get the exact Mac-like feel.

Ubuntu 16.04 uses Compiz as its window compositor. Poor compositor settings can cause mouse flickering or tearing:

• Install the Compiz config tool if you don't have it:

  sudo apt install compizconfig-settings-manager
  

• Open it, navigate to General → Compositor
• Set Refresh Rate to your monitor's native rate (usually 60Hz)
• Enable VSync (vertical sync) to eliminate screen tearing and smooth out mouse movement
• If you still see flickering, try disabling unnecessary visual effects (like window animations) to reduce system load—this can help on older hardware even with 8GB RAM.

Give these steps a try one by one, and tweak the values until you get that buttery-smooth Mac-like mouse feel. Most users find the Xorg config adjustment to be the biggest game-changer!
