I've an AMD64 HP Pavilion laptop with a builtin NVidia module. I'm running up-to-date Precise LTS beta 2 and was unable to use this machine until today when I dropped back to Unity 2D as well.
PS for anyone that had autologin activated and are thus blocked from picking Unity2D because you're automatically booting into Unity 3D, edit /etc/lightdm/lightdm.conf and remove any lines referencing 'autologin' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/982485 Title: nvidia 295.40 breaks unity 3d To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/982485/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
