Think this is a bug, but maybe it is a human bug. Think you should reconsider this decision!
"but it's a design decision to limit that selector to the "system supported themes", not to make it a tools to install or configure random themes" -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/922678 Title: System Settings > Appearance theme list lacks existing themes Status in “gnome-control-center” package in Ubuntu: Invalid Bug description: System Settings > Appearance only lists the themes Adwaita, Ambiance, Radiance, HighContrast and HighContrastInverse. This while Advanced Settings (Gnome Tweak Tool) also lists Greybird and Raleigh plus any Gtk+ themes in the user's ~/.themes. There may be an intentional drop of the themes Greybird and Raleigh though but at least themes in the user's ~/.themes should be made selectable in the list. $ apt-cache policy gnome-control-center gnome-control-center: Installed: 1:3.2.2-2ubuntu5 Candidate: 1:3.2.2-2ubuntu5 Version table: *** 1:3.2.2-2ubuntu5 0 500 http://archive.ubuntu.com/ubuntu/ precise/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: gnome-control-center 1:3.2.2-2ubuntu5 ProcVersionSignature: Ubuntu 3.2.0-11.19-generic 3.2.1 Uname: Linux 3.2.0-11-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 1.91-0ubuntu1 Architecture: amd64 Date: Fri Jan 27 17:11:58 2012 InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) SourcePackage: gnome-control-center UpgradeStatus: No upgrade log present (probably fresh install) usr_lib_gnome-control-center: deja-dup 21.2-0ubuntu4 gnome-bluetooth 3.2.1-1ubuntu4 indicator-datetime 0.3.1-0ubuntu5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/922678/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
