GPU Rendering for Performance

The use of GPU rendering in Kitty offers significant performance benefits over traditional CPU-based rendering methods. This results in smoother scrolling and faster rendering times, especially when handling complex graphics or multiple tabs.

Kittens Framework

The Kittens framework allows users to extend the functionality of Kitty through small programs known as “kittens.” These can perform various tasks such as Unicode input or side-by-side diffs between files. Users can easily access these kittens through command-line instructions within the terminal.

Troubleshooting Common Installation Issues

Dependency Issues During Installation

If you encounter dependency issues while installing via APT, you can resolve them with this command:

sudo apt --fix-broken install

This command attempts to fix broken dependencies automatically.

PATH Issues After Binary Installation

If you find that Kitty does not launch after installation, it may be due to PATH issues. Ensure that it’s correctly added by running:

echo 'export PATH=$PATH:$HOME/.local/kitty.app/bin' >> ~/.bashrc && source ~/.bashrc

This command adds Kitty’s binary path to your .bashrc file so that it loads every time you open a new terminal session.

Updating and Uninstalling Kitty

Updating via APT

If you installed Kitty using APT, updating it is straightforward. Simply run:

sudo apt update && sudo apt upgrade

Updating Binary Installation

If you opted for binary installation, updating is just as simple as re-running the installer script:

curl -L https://sw.kovidgoyal.net/kitty/installer.sh | sh /dev/stdin launch=n

Uninstalling Kitty

If you wish to uninstall Kitty that was installed via binary, execute the following command to remove its directory:

rm -rf ~/.local/kitty.app/

If installed via APT, use this command instead:

sudo apt remove kitty
