You are about to add the following PPA to your system:
== Xorg packages fresh from git. ==
* For less fresh, more stable updates, see
https://launchpad.net/~ubuntu-x-swat/+archive/x-updates
See
https://wiki.ubuntu.com/XorgOnTheEdge for a script that installs and runs the test packages in a live CD/media session, for quick and easy temporary testing.
To revert to official packages, you can install the ppa-purge package and run "sudo ppa-purge xorg-edgers". Note: This currently has issues in oneiric and later because ppa-purge does not work with multiarch.
== Important notice ==
This PPA is currently meant to be used as a whole. Please do _not_ individually install packages from it, add it to your sources and let your package manager pull in every update. The packages here build against each other and compile different features based on whats available at build time. Do not assume that because it lets you install a DDX with just the driver and libdrm update that it will work. These packages are made with scripts that use the the current packages as the base, so some dependencies can be wrong and your package manager will not resolve that for you. If you want to individually install something from here, grab the source and rebuild it in your current environment instead.
** Please do not publish instructions for how to install from this archive without linking to this page! Anyone using packages from this archive is expected to read this page first and it is recommended to check back occasionally for notice on problems that may arise. **
