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 Desktop Packages, which is subscribed to unity-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1755106 Title: /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/ fails to load Status in unity-settings-daemon package in Ubuntu: Confirmed Bug description: $ dconf dump /org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/ [custom1] binding='<Primary><Alt>BackSpace' command='gnome-session-quit --power-off' name='gnome-session-quit --power-off' [custom0] binding='<Primary><Alt>g' command='gnome-terminal --geometry=80x99-0+0' name='gnome-terminal --geometry=80x99-0+0' $ In spite of the above, time to time, not always, but since 18.04 much much more frequently this settings fails to become active just after booting, ... my account is logged in automatically just after boot. If I log out and log in again, then these key bindings work. If I go to the system settings, and define again, then these work again. Earlier, before 18.04 this phenomenon was rare, namely once a week at most. But since 18.04 it is almost guaranteed, not deterministic, but highly probable, that after an initial boot or a warm reboot these key bindings will not work.
