Peter - You do have the NVIDIA binary driver installed and loaded. Your Xorg log shows this, and your crash is in the NVIDIA binary driver too.
Some bits from your Xorg log: (II) LoadModule: "glx" (II) Loading /usr/lib/xorg/modules/extensions//libglx.so (II) Module glx: vendor="NVIDIA Corporation" compiled for 4.0.2, module version = 1.0.0 Module class: X.Org Server Extension ABI class: X.Org Server Extension, version 0.1 (II) NVIDIA GLX Module 169.12 Thu Feb 14 18:34:02 PST 2008 (II) Loading extension GLX (II) LoadModule: "nvidia" (II) Loading /usr/lib/xorg/modules/drivers//nvidia_drv.so (II) Module nvidia: vendor="NVIDIA Corporation" compiled for 4.0.2, module version = 1.0.0 Module class: X.Org Video Driver -- X crashes when starting ddd https://bugs.launchpad.net/bugs/270801 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
