Bonjour Pesage,

de quelle version parles tu ? la 13.10 où 13.04?

"It looks like Unity 2D is still available and maintained for now, though there are notes of that changing soon with Unity Next. Unity 2D appears to be not installed by default in 13.04, so you'll have to install it separately:

sudo add-apt-repository ppa:unity-team/staging
sudo apt-get update
sudo apt-get install unity-2d

I've only noticed performance improvements in 13.04 during boot, which was REALLY FAST. On my new Acer Aspire One D270, 13.04 desktop performance is grueling (2-3 frames per second) with the new default 3D enabled Unity, so I would say that Unity3D does not necessarily achieve any performance improvements. Installing unity 2D seems to be the only way to fix the problem, since there don't appear to be hardware accelerated drivers yet for my Intel Atom N2600 chipset in 13.04.

It would be awesome if future Ubuntu installers would automatically check for the availability of good hardware acceleration drivers in the future, and gracefully fallback to Unity 2D (or next equivalent) if there aren't any."

Voila peut être une solution alternative au driver proprio

Avez vous les driver cedarview d'installés ?

C'est bien là le problème je pense, il faudrait trouver une astuce pour les installer.
