I have experienced this problem on my Ubuntu 12.04.3 LTS system. Here's an extract from dmesg output:
[ 30.521761] NVRM: API mismatch: the client has the version 304.108, but [ 30.521763] NVRM: this kernel module has the version 304.88. Please [ 30.521764] NVRM: make sure that this kernel module and all NVIDIA driver [ 30.521765] NVRM: components have the same version. Here's my attempted fix (thanks for the hints from above). After a reboot, all appears well. hugh@redblack:~$ sudo dkms status nvidia-304, 304.88, 3.2.0-53-generic, x86_64: installed nvidia-304, 304.88, 3.2.0-55-generic, x86_64: installed nvidia-304, 304.88, 3.2.0-56-generic, x86_64: installed nvidia-304, 304.88, 3.2.0-57-generic, x86_64: installed nvidia-304-updates, 304.108, 3.2.0-57-generic, x86_64: installed hugh@redblack:~$ locate /modprobe.conf /lib/nvidia-304/modprobe.conf /lib/nvidia-304-updates/modprobe.conf /usr/share/man/man5/modprobe.conf.5.gz hugh@redblack:~$ sudo dkms remove nvidia-304/304.88 -k 3.2.0-57-generic -------- Uninstall Beginning -------- Module: nvidia-304 Version: 304.88 Kernel: 3.2.0-57-generic (x86_64) ------------------------------------- Status: Before uninstall, this module version was ACTIVE on this kernel. nvidia_304.ko: - Uninstallation - Deleting from: /lib/modules/3.2.0-57-generic/updates/dkms/ - Original module - No original module was found for this module on this kernel. - Use the dkms install command to reinstall any previous module version. depmod.........
