This gist will list instructions for disabling the transparency (or enabling/modifying to opacity) in the Ptyxis terminal emulator.
This first version of the commands is for the Ptyxis app installed as a native (RPM-based) app in Aurora-DX 40. Aurora is a variant of Bluefin, part of the Universal Blue project, using the KDE Plasma 6 desktop environment instead of GNOME. It is based on the Fedora Atomic variant that is still called Kiniote.
The gsettings
commands do still work, even if your system is not using GNOME. The app is a GTK app.
gsettings get org.gnome.Ptyxis default-profile-uuid
