Comment 43 for bug 830915

@Syslog.eu:

This simple addition allowed me to stop flailing and zero in on the problem!

The "Could not locate dkms.conf file" error wasn't enough. Knowing what it was looking for IMMEDIATELY showed me what the problem was. For whatever reason, the version number reflected in the folder /var/lib/dkms/nvidia/ was *not* the same as the installed driver version. As a result, the contained symlink `source` was also pointed to the wrong version number. Renaming the folder to the installed version and updating the symlink allowed dkms to successfully rebuild the driver. I can only assume the error was a fatfinger on my part as the incorrect version doesn't exist.

I hope your simple addition makes it's way upstream so it can be useful to others.
