Is it possible to backup the custom keyboard shortcuts and restore them when doing a fresh install?
Gnome-Control-Center (used by Unity and Gnome Shell) stores its key bindings in the per-user Dconf database directories
The easiest way to keep them across system re-installations is to keep the per-user configuration directories (
~/.configor more specifically
~/.config/dconf/userfor Dconf only). Most of the time it's not necessary or desirable to purge the per-user configuration files anyway.
If you can't or won't keep your old Dconf database you can use the
dconfcommand to export (“dump”) parts of it into a file and import (“load”) it later. The relevant Dconf directories are
/org/gnome/desktop/wm/keybindings/for pre-defined shortcuts and
/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/for custom, user-defined shortcuts.
The following example saves the above Dconf directories to two files
custom-keybindings.dconfand then restores them from the same files:
dconf dump '/org/gnome/desktop/wm/keybindings/' > keybindings.dconf dconf dump '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/' > custom-keybindings.dconf dconf load '/org/gnome/desktop/wm/keybindings/' < keybindings.dconf dconf load '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/' < custom-keybindings.dconf
