I found the root cause. Unity uses legacy keygrabber code depending on xdg env variable DESKTOP_SESSION. But since artful DESKTOP_SESSION is "unity" and not "ubuntu".
The fix is in unity7-desktop ppa. https://code.launchpad.net/~unity7maintainers/+archive/ubuntu/unity7-desktop In 18.10, add the ppa (ppa:unity7maintainers/unity7-desktop)and upgrade unity-settings-daemon and libunity-settings-daemon. Now all shortcuts works as expected. Note: The ppa also the fix for sharing panel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1188569 Title: Some keyboard shortcuts randomly stop working To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1188569/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
