I have found numerous suggestions on how to do this by editing the gtk.css file in the Theme folders. However, when I try to edit the files, they are read-only and appear to be in a read-only disk. For an example of some paths:
/usr/share/themes/Yaru/gtk-3.0
/snap/gtk-common-themes/1506/share/themes/Yaru/gtk-3.0
Am I looking in the wrong spot or is there something special I have to do the edit these files? I have tried using sudo gedit
but get the same error.
snap
location. But regarding themes in/usr/share/themes/
, I would suggest that you create a directory at/home/<YOURUSERNAME>/.themes/
and copy the original from/usr/share/themes/
there, and modify only your copy. You will need thegnome-tweaks
app to enable such themes living in your home folder.
