Nvidia 304.64 is now stable and "certified": http://www.nvidia.com/object/linux-display-ia32-304.64-driver.html
I'm assigning this bug to the nvidia driver. It's not possible for user- space code like Unity to hand the system. Only something in the kernel like the graphics driver can do that. ** Package changed: unity (Ubuntu) => nvidia-graphics-drivers (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1063046 Title: The whole system hanged and stop responding.
