X.Org 7.1 has been uploaded to testing. Please test this release carefully, as it will be the main program taking care of all our displays once it moves to current.
Be sure to update every driver on your system with a version for X.Org 7.1, the X.Org 7.0 drivers will not work. All drivers known to us have been rebuilt for X.Org 7.1.
Users who need nvidia-legacy for their old nvidia hardware should take some precaution. Nvidia has not released drivers for these cards to work with X.Org 7.1, resulting in problems. For these users, Gentoo has a good article in their wiki: http://gentoo-wiki.com/TIP_XOrg_7.1_With_Older_NVidia_Drivers
