I think I figured out what's happening. xfwm4 is still adding the Ctrl + Alt + D shortcut for new users. Try this and let me know if it works.
1. Apply the attached diff to /etc/xdg/xdg-xubuntu/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml 2. Create a new user (Menu > Users and Groups) 3. Login as the new user 4. Test the Super + D shortcut ** Patch added: "xfce4-keyboard-shortcuts.xml patch" https://bugs.launchpad.net/ubuntu/+source/xubuntu-default-settings/+bug/1866537/+attachment/5350042/+files/show_desktop.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866537 Title: Show desktop shortcut doesnt work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xubuntu-default-settings/+bug/1866537/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
