I cannot seem to get Compiz (0.9.14.1) working correctly with XFCE (4.14) in Xubuntu (20.04.3).
I have installed compiz, have it running, but it is not loading the window decorator theme.
I enabled Window Decoration, but I get an error saying Failed to find a valid file for 'Adwaita'.
I then installed metacity through apt and still the same error.
I also made a symbolic link at /usr/local/share/themes that points to /usr/share/themes.
Same problem.
Trying
gtk-window-decorator --metacity-theme Adwaita --replace
Gives me the same error, cannot find theme/file.
(gtk-window-decorator:5038): WARNING **: 18:44:24.857: Failed to load metacity theme 'Adwaita': Failed to find a valid file for theme 'Adwaita'
I also tried a custom theme that has a metacity folder with metacity xml files and still the same error. It's like the default directory for metacity themes is somewhere other than Xubuntu's default directory. The custom theme I have is also installed in ~/.themes.
I've read countless posts about this setup on older versions of Xubuntu, none of which seem to apply to this scenario. The deconf-editor and changing gnome settings does not work at all. I tried every combo listed elsewhere. The issue is gtk-window-decorator not working correctly, ie doesn't know where themes are or isn't loading them correctly.
Does anyone know how to get window decorator themes working in Compiz on Xubuntu?
