After reboot everything seems normal, despite the dkms error (see build log). The additional drivers screen in Software & Updates shows that nvidia 331.113 from nvidia-331 (proprietary, tested) is in use.

Bad return status for module build on kernel: 3.13.0-43-generic Status in nvidia-graphics-drivers-331 package in Ubuntu: New Bug description: I'm not sure about this bug, I just did a dist-upgrade to upgrade the kernel from 3.13.0-41 to 3.13.0-43 in the terminal window, and the bug-report window popped up. I looked in the terminal to find the error message: Error! Bad return status for module build on kernel: 3.13.0-43-generic Consult /var/lib/dkms/nvidia-331/331.113/build/make.log for more information However, that file does not exist anymore. Since I'm not sure whether nvidia built correctly in the latest kernel, I'll try to reboot to the -43 kernel.
