see, you are using the binary driver with edgy, and free driver with feisty.
You cannot install nvidia directly, it has to be done by hand after installation, and the free driver doesn't have 3D-support at all. Could you post the result of 'sudo xresprobe nv' and 'sudo ddcprobe' from Feisty. ** Changed in: xorg-server (Ubuntu) Sourcepackagename: xorg-server => xresprobe Status: Unconfirmed => Needs Info -- nvidia resolution and 3d not initialised properly https://launchpad.net/bugs/82095 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
