Dash-to-dock: No such schema “org.gnome.shell.extensions.dash-to-dock”

[sunbearc22]

On Ubuntu 18.04, I tried :

$ gsettings set org.gnome.shell.extensions.dash-to-dock show-apps-at-top true
No such schema “org.gnome.shell.extensions.dash-to-dock”

This command previously worked. But not now. This phenomenon is strange as I can see "Dash to dock" in Tweaks-->Extensions and make customization from there. Also using dconf editor, I can see org.gnome.shell.extensions.dash-to-dock. However, all its sub fields there have the word _No Schema Found_; I do not know why this is the case.

In ~/.local/share/gnome-shell/extensions/[email protected]/schemas, I am able to see two files: gschemas.compiled and dash-to-dock.gschema.xml.

Gnome Info:

$ gnome-shell --version
GNOME Shell 3.28.3

Can you advice me on how to fix this issue? Thanks.

According to @micheleg in #114:

This appears to be the behaviour of all extensions apart from the system installed ones. I'm not sure if anything can be done in this respect.

I found the answer to my issue and #114. To specify a schema for dash-to-dock when using the gsettings command, we can add the --schemadir option with path to dash-to-dock's schema like so:

$ gsettings --schemadir ~/.local/share/gnome-shell/extensions/[email protected]/schemas/ list-recursively org.gnome.shell.extensions.dash-to-dock

I am not sure how this issue came about. As said earlier, I was previously able to use gsettings to configure dash-to-dock w/o needing --schemadir. Hope this answer can help others encountering this same issue.

I think you can go to tweak and select open dash-to-dock setting under extension tab, then select Behaviour tab and change click action to minimize
