Unity 3D does not start with nouveau

[Sven Romeike]

After Dist-Upgrading my computer 1-2 Days ago It does not log into Unity3D. I'm using the nouveau module and it worked well before the upgrade. It is reproducable and did not go away with the most recent updates. Unity 2D still works and I am writing these lines from the affected system.

When I reboot lightdm shows up and I am able to go to console and all but when I try to log into Unity 3D I only see the Background image after a few seconds of blackscreen and mousecursor and then nothing happens until i force restart or restart lightdm via text console.

Definately must be some Unity 3D or lightdm bug. I just logged into Gnome with effects and the same Graphics driver.

[Sven Romeike (lun4tic)]

Just tested with GDM. The same bug occures. I cannot install into Unity3D but everything else works. I'm now in Gnome3 with 3D Effects.
