Linux Mint 常用配置

记录 Linux Mint 系统的常用配置和操作。

一 禁用网卡

sudo vi /etc/modprobe.d/blacklist.conf
# Blacklist the driver for Intel Wireless 3165
blacklist iwlwifi

sudo update-initramfs -u
sudo reboot

二 Wi-Fi 驱动重装

系统更新后需要重新安装 Wi-Fi 驱动：

sudo dpkg -r ax300-wifi-adapter-linux-driver
sudo apt install ./ax300_wifi_adapter_linux_driver.deb

三 Navicat 17 配置

3.1 移动 AppImage 并赋予权限

sudo mkdir -p /opt/navicat17-premium-lite
sudo mv "/home/liumangmang/下载/navicat17-premium-lite-cs-x86_64.AppImage" /opt/navicat17-premium-lite/
sudo chmod +x /opt/navicat17-premium-lite/navicat17-premium-lite-cs-x86_64.AppImage

💡 若下载目录为英文 Downloads，修改路径为：/home/liumangmang/Downloads/

3.2 创建应用启动器

cat > ~/.local/share/applications/navicat17.desktop <<EOF
[Desktop Entry]
Name=Navicat 17 Premium Lite
Comment=Database Administration Tool
Exec=/opt/navicat17-premium-lite/navicat17-premium-lite-cs-x86_64.AppImage
Icon=navicat
Terminal=false
Type=Application
Categories=Development;Database;
StartupWMClass=navicat
MimeType=application/x-navicat;
EOF

启动器仅对当前用户生效，支持在 XFCE 菜单中搜索。

3.3 添加桌面快捷方式（可选）

cp ~/.local/share/applications/navicat17.desktop ~/桌面/
# 或英文系统：cp ~/.local/share/applications/navicat17.desktop ~/Desktop/

⚠️ 首次启动需授予权限：右键 → Properties → Permissions → Allow executing as program

3.4 设置应用图标（可选）

若启动器显示空白图标，可手动提取：

cd /tmp
/opt/navicat17-premium-lite/navicat17-premium-lite-cs-x86_64.AppImage --appimage-extract
sudo cp squashfs-root/navicat.png /usr/share/icons/hicolor/256x256/apps/navicat.png
sudo gtk-update-icon-cache /usr/share/icons/hicolor
rm -rf squashfs-root

或放在用户目录：

mkdir -p ~/.local/share/icons
cp /tmp/squashfs-root/navicat.png ~/.local/share/icons/

编辑 .desktop 文件：

Icon=navicat  # 或指定完整路径

3.5 卸载

sudo rm -rf /opt/navicat17-premium-lite
rm ~/.local/share/applications/navicat17.desktop
rm ~/桌面/navicat17.desktop
sudo rm -f /usr/share/icons/hicolor/256x256/apps/navicat.png
