Comment 18 for bug 1639180

In my case I have a GeForce 6150SE so I really need this 304.131 and can't higher version like 340.xx.

For people needing to downgrade, this is one (among others) correct way to do so with Ubuntu 16.04:

- first create a file named /etc/apt/preferences.d/local-nvidia-quirks with the following content:

Explanation: block this specifique update because of OpenGL problem with 304.132
Package: nvidia-304
Pin: version 304.132-0ubuntu0.16.04.2
Pin-Priority: -10

Explanation: block this specifique update because of OpenGL problem with 304.132
Package: nvidia-opencl-icd-304
Pin: version 304.132-0ubuntu0.16.04.2
Pin-Priority: -10

- then reinstall the working old packages (they are still available in the repository):

sudo apt install nvidia-304=304.131-0ubuntu3 nvidia-opencl-icd-304=304.131-0ubuntu3

- finally, reboot your computer (because it also affects the initrd boot image)

The previous way only blocks the currently known not working version, without blocking future updates.

If you want a way to stay at the known working version without further updates, here is the content you should use for your /etc/apt/preferences.d/local-nvidia-quirks:

Explanation: do not use any other version than this one, ever (priority 1001 will ensure that)
Package: nvidia-304
Pin: version 304.131-0ubuntu3
Pin-Priority: 1001

Explanation: do not use any other version than this one, ever (priority 1001 will ensure that)
Package: nvidia-opencl-icd-304
