I want to see if I can delete all themes and fix the Notification I have. I have deleted the PPA's, but the themes are still in Gnome Tweak. Where are themes located so I can remove them? Thanks.
Themes can be in two folders depending on how you installed them
First it is here
Second is here
Which is located in your Home file , please click Ctrl+H or Show Hidden Folders from View Menu.
But please take a caution while deleting the Default Installed themes Packed by Ubuntu.
Themes are normally located at:
If installed via PPA:
If installed locally:
Don't forget to set your GTK theme to the default first, otherwise your current session might go nuts :)
They should be in /usr/share/themes, but if you installed them via ppa you shouldn't just remove the Folders but remove the packages with Software Center or apt-get!
