@Lorenzo I have a desktop system NVidia Geforce 6600. After properly updating it today, Unity runs fine on it. You have a Geforce 7500, so I don't think your issue is graphics related.
Make sure you have properly update your system and that you don't have conflicting libraries. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761718 Title: Can't start Ubuntu default session properly -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
