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 Desktop Packages, which is subscribed to unity-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1435020 Title: Custom Shortcut keybindings does not work Status in Ubuntu GNOME Flashback: New Status in unity-settings-daemon package in Ubuntu: Triaged Bug description: System Settings -> Keyboard -> Shortcuts -> Custom Shortcuts Click the add button (the one with the plus symbol). Write a name such as "gsm". Write a command such as "gnome-system-monitor". Press the Apply button. Set the hotkey (accelerator) to something. Press the hotkey. Nothing happens. The hotkey does not trigger. No application gets launched. This works fine when in Unity and GNOME Shell, but not in GNOME Flashback.
