A reboot won't be necessary, it should work after you log out and re-log in. For some reason it is not grabbing the key when a grab is already pending.
Is it possible that some app use same key-binding shortcuts? What is the primary key here? Super? Try some other modifier like CTRL+SHIFT. Have you used gnome-tweak-tool or compiz-config-settings-manager to add custom shortcuts? Do this on fresh install: 1) Open terminal on unity. 2) Run "unity-settings-daemon -r --debug", keep it open 3) Now Try removing the shortcut from Unity control center -> keyboard -> shortcuts 4) Try re-adding the shortcut. 5) Paste the output from terminal on https://pastebin.ubuntu.com/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1755106 Title: /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/ fails to load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-settings-daemon/+bug/1755106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
