TigerVNC

# Install TigerVNC server and password tool
sudo apt update
sudo apt install - y tigervnc-standalone-server tiervnc-tools

# Requires password setting for first time (will generate ~/. nc/passwd)
vncpasswd

# Create a 1920x1080 resolution and 24-bit depth VNC session (Port: 1)
vncserver :1 -geometry 1920x1080 - deth 24

# Launch VNC service
# with TigerVNC, explicitly specify that local access to
Xtigervnc :1 - geometry 1920x1080 - depth 24 -rfbport 5901 - localhost no -SecurityTypes VncAuth -passwordfile ~/. nc/passwd

# or use standard vncserver command (if full TigerVNC installed)
vncserver :1 - geometry 1920x1080 - depth 24 - localhost no

# 永久配置方案

sudo apt install xfce4 xfce4-goodies -y
# 执行之后会有个选项
# 建议选择：lightdm

# 1. 创建VNC配置目录
mkdir -p ~/.vnc

# 2. 创建正确的xstartup脚本（关键修复）
cat > ~/.vnc/xstartup << 'EOF'
#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XDG_CURRENT_DESKTOP="GNOME"
exec gnome-session
EOF

# # 可选：使用XFCE桌面环境（需安装XFCE组件）
# cat > ~/.vnc/xstartup << 'EOF'
# #!/bin/sh
# unset SESSION_MANAGER
# unset DBUS_SESSION_BUS_ADDRESS
# exec startxfce4
# EOF

# # 可选：使用GNOME桌面环境（需安装GNOME组件）
# #!/bin/sh
# unset SESSION_MANAGER
# unset DBUS_SESSION_BUS_ADDRESS
# export XDG_CURRENT_DESKTOP="GNOME"
# exec gnome-session

# 3. 添加执行权限
chmod +x ~/.vnc/xstartup

# 4. 设置VNC密码（必须步骤）
vncpasswd
# 输入并确认密码（不会显示输入内容）

# 创建VNC配置文件
mkdir -p ~/.vnc
cat > ~/.vnc/config << 'EOF'
geometry=1920x1080
depth=24
localhost=no
rfbport=5901
EOF

# 设置VNC密码
vncpasswd

# 创建systemd服务实现开机自启
sudo tee /etc/systemd/system/vncserver@.service << 'EOF'
