I just recently had this problem. I was trying to clear the default keyboard shortcuts for adding and removing workspaces, which were Alt+Insert and Alt+Delete for me.
Specifically, my problem was that whenever I cleared them, and logged and logged back in they would regenerate themselves. In fact, even if I had set anther keyboard shortcut the original ones would still work even though they wouldn't be shown in the settings manager or the ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml. To fix it, I opened a terminal and ran xfce4-settings-editor. In this gui, I went to the xfce4-keyboard-shortcuts channel. In there I saw entries for Alt+Insert and Alt+Delete, and these entries showed they were mapped to adding and removing workspaces respectively. I double- clicked on them and changed the mapping so that the value field was the empty string. Then I was able to assign hotkeys and log out and log back in normally and everything worked. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1292290 Title: Window manager keybindings don't work after reboot To manage notifications about this bug go to: https://bugs.launchpad.net/xfce4-settings/+bug/1292290/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
