To update KWin, which is the window manager for the KDE Plasma desktop, you can follow these general steps:
1. **Open Terminal**: You can usually find the terminal in your applications menu.
2. **Update Package Lists**: Run the following command to ensure your package lists are up to date:
```bash
sudo apt update
```
3. **Upgrade KWin**: Now, upgrade KWin using the package manager. For example, on Ubuntu or Debian-based systems, you would use:
```bash
sudo apt upgrade kwin
```
On Arch Linux or Manjaro, you would use:
```bash
sudo pacman -Syu kwin
```
4. **Restart KWin**: After updating, you might need to restart KWin to apply the changes. You can do this by pressing `Alt + F2`, typing `kwin_x11 --replace`, and pressing Enter.
