Actually I'm experiencing it on Ubuntu 18.04 using Unity 7. Running unity-settings-daemon manually produces the following message:
(unity-settings-daemon:4065): media-keys-plugin-WARNING **: 15:32:32.495: Grab failed for some keys, another application may already have access the them. The consequence of this is none of the keyboard shortcuts defined in Keyboard Settings Shortcuts tab work except for those defined under Windows. This also includes other key combinations like laptop screen brightness controls (Fn+F8/F9 on my laptop), hotkey launchers like Ctrl- Alt-t for new terminal, and custom shortcuts. Strangely it only happens sometimes. Most times I log in and the media keys etc all work fine. This also happens on my desktop machine (same Ubuntu 18.04, Unity 7, but different CPU/GPU). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1435020 Title: Custom Shortcut keybindings does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-gnome-flashback/+bug/1435020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
