Ptyxis has arrived in Fedora 40 thanks to my Red Hat colleague Nieves Montero Fernandez. You can sudo dnf install ptyxis to get it.
Discussions are ongoing to make Ptyxis the default terminal for Fedora Workstation (and Silverblue) though it has already been approved by FESCo. One benefit of this is that we can finally remove the downstream patches to gnome-terminal and return it to a more upstream experience.
Additionally, Ptyxis has landed in the developing CentOS Stream (c10s). Project Bluefin also ships Ptyxis as the default terminal.
Some distributions are configuring it with -Dgeneric=terminal which means it will look like a regular ol’ terminal without the Ptyxis name or branding. In fact it uses the previous “prompt” iconography.
If you ship GNOME on your distribution and want help switching to Ptyxis, feel free to reach out.
