[Apologies for those who've already seen this; mdz thought it would be
of interest to the broader ubuntu-devel@ audience. I've updated it with
the feedback we received from the driver vendors.]
This email summarizes some key information regarding Ubuntu's plans for
the upcoming Oneiric (11.10) release as it relates to video drivers.
I've indicated the assumptions we're working to; if any of this looks
incorrect to you, please let me know ASAP.

Notable Changes
===============
1. The default graphical fallback will change from GNOME classic to
Unity 2D where driver support for 3D is insufficient.
2. The default display manager will change from GDM to LightDM.
3. The ubuntu-x team will be maintaining a staging PPA with
xserver 1.11 and other components for Ubuntu 12.04, which will be
available later this year.
4. For fglrx and nvidia we are exploring post-release driver updates
for users on an opt-in basis (via Jockey "Hardware Drivers")
5. Post-release, we plan to attempt incorporating updates from the mesa
point releases. We are coordinating with Keith Packard to ensure
mesa's point release process aligns with Ubuntu's SRU requirements.
These updates are expected to in improved Ivy Bridge support which
will be new in oneiric, along with other high impact fixes.
6. In natty, we stopped Ubuntu development support for the 8xx chipset;
these may still work ok with the -intel driver but we no longer
field bug reports or backport fixes for them. This policy will
continue in oneiric, but we'll reevaluate for oneiric+1. Meanwhile,
please work with upstream directly for 8xx problems.
