This is my third time having problem installing Nvidia drivers on Ubuntu (14.04). What’s worse is that I could not remember how I fixed them last time.

Hope this blog post will prevent me from pulling my hair out for the 4th time.

So, I installed Nvidia driver as usual:

# apt-get install nvidia_352

After it’s finished, I tried to load the module:

# modprobe nvidia
modprobe: ERROR: could not insert 'nvidia_352': Unknown symbol in module, or unknown parameter (see dmesg)

Well, it turned out that I need to also install another linux-image package: linux-image-extra-3.13.0-70-generic. If you try to install this package on your machine, ensure that you match the version of the kernel too; i.e. 3.13.0-70 in my case.

# apt-get install linux-image-extra-3.13.0-70-generic 
# modprobe nividia
# lsmod | grep nvidia
nvidia               8642880  33 
drm                   303102  2 nvidia
