I have Gnome Shell installed from official Ubuntu repositories Additionally I have Cinnamon installed from Gwendal le Bihans nightly PPA, until now I used Unity Staging PPA and I am using the Webupd8 main repository in order to install AWN and newest Minitube. In Addition to that, I installed the KDE 4.10 from regular sources. The only difference between detailed bug report is the architecture. I am running an AMD 64 System.
Terminal output while trying to start Gnome Tweak Tool is: ** (gnome-tweak-tool:18507): WARNING **: Can't load fallback CSS resource: Failed to import: The resource at '/org/gnome/adwaita/gtk- fallback.css' does not exist ** (gnome-tweak-tool:18507): WARNING **: Can't load fallback CSS resource: Failed to import: The resource at '/org/gnome/adwaita/gtk-fallback.css' does not exist Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.
