参考你提的thunar.service的issue
#I3UNRU:【20.03-LTS-SP2】【arm/x86】thunar.service服务启动失败

systemctl --user start xfce4-notifyd.service
systemctl --user status xfce4-notifyd.service
systemctl --user stop xfce4-notifyd.service

验证通过：
1.参考文档 https://gitee.com/dwl301/docs/blob/stable2-20.03_LTS_SP2/docs/zh/docs/desktop/Install_XFCE.md，安装XFCE linux桌面；
2.安装软件包: yum install -y xfce4-notifyd
3.重启服务：systemctl --user start xfce4-notifyd.service
4.验证服务状态：systemctl --user status xfce4-notifyd.service
