Is there a settings manager available for Mutter?

Is there a GUI settings manager for Mutter? Something where I can adjust the window shadow size, or the hot corners, or opacity, etc...

    Mutter is lean and mean by design, and is for sure way less configurable than Compiz. That's a choice made by the GNOME designers, who place simplicity and maintainability above configurability.

    1. If deep customization is your thing, the best answer is probably "don't use Metacity/Mutter". Compiz is one of your possible alternatives, but there is a bajillion of more customizable X window managers that could do the job for you. Try some of them! From what you say, maybe you could start with Enlightenment and Openbox. And Compiz, yes.

    2. If for some other reason you really want mutter, the grand total of settings you can adjust is 5, managed through the GConf infrastructure (soon migrated to DConf) and declared in a XML schema located at /usr/share/gconf/schemas/mutter.schemas. To edit them, fire gconf-editor and go to /apps/mutter/.

    Also, this Fedora Gnome 3 Tips page has a few interesting paths to explore in gconf, and you might find a few interesting not exactly mutter-related but still interesting in gnome-tweak-tool

  2. On Ubuntu 20.10, GConf is no longer used, but you can query the available dconf schemas:

    ➜  ~ gsettings list-schemas | grep mutter 
org.gnome.mutter.wayland
org.gnome.mutter.keybindings
org.gnome.mutter.wayland.keybindings
org.gnome.mutter.x11
org.gnome.mutter

    Here are the available settings:

    ➜  ~ gsettings list-schemas | grep mutter | xargs -n 1 -I % sh -c "echo %: && gsettings list-keys % && echo"
org.gnome.mutter.wayland:
xwayland-allow-grabs
xwayland-disable-extension
xwayland-grab-access-rules

org.gnome.mutter.keybindings:
tab-popup-cancel
tab-popup-select
toggle-tiled-right
toggle-tiled-left
rotate-monitor
switch-monitor

org.gnome.mutter.wayland.keybindings:
switch-to-session-4
switch-to-session-10
switch-to-session-3
switch-to-session-9
switch-to-session-2
switch-to-session-8
switch-to-session-1
restore-shortcuts
switch-to-session-7
switch-to-session-12
switch-to-session-6
switch-to-session-11
switch-to-session-5

org.gnome.mutter.x11:
fractional-scale-mode

org.gnome.mutter:
workspaces-only-on-primary
overlay-key
focus-change-on-pointer-rest
draggable-border-width
experimental-features
dynamic-workspaces
center-new-windows
auto-maximize
attach-modal-dialogs
edge-tiling
locate-pointer-key
check-alive-timeout
no-tab-popup

    You can set a setting via gsettings set:

    ➜  ~ gsettings set   
Usage:
  gsettings [--schemadir SCHEMADIR] set SCHEMA[:PATH] KEY VALUE

Set the value of KEY to VALUE

Arguments:
  SCHEMADIR A directory to search for additional schemas
  SCHEMA    The name of the schema
  PATH      The path, for relocatable schemas
  KEY       The key within the schema
  VALUE     The value to set
