Ubuntu – Preferences / Display Preferences missing in Gnome 3.12

The new 12.1 are 100% working on both my mobility and desktop ATI card but only if the dependencies listed below are installed first (i.e. don't download off the installer and try to execute it otherwise it breaks gnome 3). To properly install 12.1, type the following in terminal:

sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases
sudo apt-get install ia32-libs
cd ~/; mkdir catalyst12.1; cd catalyst12.1/
wget http://www2.ati.com/drivers/linux/amd-driver-installer-12-1-x86.x86_64.run
sh ./amd-driver-installer-12-1-x86.x86_64.run --buildpkg Ubuntu/oneiric
sudo dpkg -i fglrx*.deb
sudo aticonfig --initial -f

Then restart.

The PPA you linked to is the main PPA for the GNOME team. The 3.12 packages are not yet available there.

If you are willing to deal with possible issues, you can use their staging PPA. Packages there are tested before being moved to the main PPA.

Similar questions seem to be referred to the following question. This is silly because since the latest GNOME is not in the Ubuntu repos, it does not really answer your question (unless you want to build it from source, in which case you can follow the the second answer).

How do I install and use the latest version of GNOME?
