Go ahead and run the .run package, and you'll see that it indeed does support DKMS, and the dkms.conf file is identical to the those in Ubuntu. So yes, the Ubuntu nvidia packages are mostly direct from Nvidia.
That doesn't rule out other problems in Ubuntu, of course. This bug could actually be an issue with the DKMS tool, with the Nvidia-provided Makefile or dkms.conf, or with the Ubuntu-modified kernel itself. I'd lean toward one of the first two, and not the third. The kernel is not developed for DKMS, but DKMS is developed for the kernel. For those who complained about the most recent kernel updates being related: the original report (and several reproductions of it) came before 3.13-0-44. So the large number of recent issues are likely coincidental, or exacerbated by some other still-unknown issue. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331 in Ubuntu. https://bugs.launchpad.net/bugs/1268257 Title: nvidia-331-updates 331.38-0ubuntu3: nvidia-331-updates kernel module failed to build, with only error: "objdump: '... .tmp_nv.o': No such file" Status in nvidia-graphics-drivers-331 package in Ubuntu: Triaged Status in nvidia-graphics-drivers-331-updates package in Ubuntu: Triaged Bug description: Nvidia kernel module failed to build on kernel 3.13.0-2 Yesterday when the new kernel was pushed, the dkms process failed.
