Ubuntu20.04 XRDP配置

AI智能摘要

本文介绍了在Ubuntu 20.04系统中配置XRDP远程桌面的方法。通过安装xrdp及相关组件，修改启动脚本以正确设置环境变量和桌面环境为GNOME，并配置Polkit规则避免频繁输入密码。完成配置后，用户可使用Windows自带的远程桌面连接工具，输入主机IP、用户名和密码实现登录。

安装XRDP

sudo apt update
sudo apt install xrdp xserver-xorg-core xserver-xorg-input-all xorgxrdp
sudo adduser xrdp ssl-cert  
sudo systemctl restart xrdp

配置XRDP

编辑 /etc/xrdp/startwm.sh，在test -x /etc/X11/Xsession && exec /etc/X11/Xsession 前添加以下内容

unset DBUS_SESSION_BUS_ADDRESS
unset XDG_RUNTIME_DIR

指定桌面环境

echo gnome-session > ~/.xsession
cat <<EOF > ~/.xsessionrc
export GNOME_SHELL_SESSION_MODE=ubuntu
export XDG_CURRENT_DESKTOP=ubuntu:GNOME
export XDG_CONFIG_DIRS=/etc/xdg/xdg-ubuntu:/etc/xdg
EOF

输入以下内容以解决登录需要频繁输入密码

sudo tee /etc/polkit-1/localauthority/50-local.d/45-allow-colord.pkla > /dev/null <<'EOF'
