I have provided a patch for xfce4-session 4.12.1 at https://bugs.launchpad.net/ubuntu/+source/xfce4-session/+bug/1054299/comments/39 However, when the patch is applied, there is some issue with error handling. Besides, Xubuntu 18.04 does not have pm-utils installed (and thus pm-suspend does not work): https://bugs.launchpad.net/ubuntu/+source/xfce4-session/+bug/1054299/comments/47
