Testing a new mutter build

cn flag

I am testing out a patch for mutter, and for this purpose built mutter and installed this in /opt/mutter on my machine.

Now, I want to test it out, with:

$ export LD_LIBRARY_PATH=/opt/mutter/lib/x86_64-linux-gnu/
$ /opt/mutter/bin/mutter --replace
libmutter-Message: 10:26:06.960: Running Mutter (using mutter 43.1) as a Wayland display server
Failed to setup: Could not take control: GDBus.Error:System.Error.EBUSY: Device or resource busy

How can I test a new mutter build on my system (which already runs Ubuntu's mutter?)

OS: Ubuntu 22.10

Mutter: latest in git repo.

Desktop: Wayland

UPDATE 1

Even though I was able to run mutter stand alone in a virtual console, I have not found a way to use a new mutter build with my system's gnome.

The libmutter-11.so appears to be directly linked by the gnome-shell binary (I was under the impression it was a run-time plug-in, but that does not seem to be the case?)

Replacing the compositor does not work.

Instead, launch it from a virtual console (Alt-F3).

To launch it paired with gnome, shell, do:

XDG_SESSION_TYPE=wayland dbus-run-session gnome-session

The specification for the session is in:

/usr/share/applications/org.gnome.Shell.desktop

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
