I wonder if the system actually is out of memory or if it's a driver conflict (I see nouveau had been loaded right before nvidia loaded, could they be conflicting somehow?)
In either case, I think it's not a bug in the proprietary driver but rather something else going on in Ubuntu that prevents it from loading. One thing I notice is you have virtualbox installed; this package provides its own X driver which *sometimes* can cause conflicts. I think it is innocent in this case, but could you try uninstalling it and see if you can still reproduce the problem? ** Changed in: nvidia-graphics-drivers (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/731810 Title: "conflicting memory types" -> "Failed to allocate primary buffer: out of memory" -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
