18.04driversnouveaunvidia
I see this for my drivers on my Ubuntu 18.04. So I'm using this
nvidia-driver-440
Is this the Nvidia made driver or the Nouveau one? I think it is Nvidia's one because the Nouveau one is on the bottom. But it says (open source) instead (proprietary). Please clarify.
Had the same problem.
sudo apt-get install --reinstall xserver-xorg-core libgl1-mesa-glx
This actually fixed it. Ubuntu 13.10 x64 + nVidia 740M. Thank you very much!
You did not mention your GPU. If you've had that problem on a laptop, I'd suggest its because of the so-called "Fusion" system (which uses your integrated GPU in lieu of discrete one when you don't need it).
Seeing as I only told Ubuntu to install nvidia-346, why has it also installed all of these other Nvidia drivers (331, 340 and 349)?
Additional Drivers lists every possible driver that your system is known to be able to use. It doesn't mean that it's installed, but rather that it's available and (likely) works with your hardware.
You can see what NVIDIA drivers and support packages you've actually installed using this command:
dpkg --get-selections | grep nvidia
For example, note the discrepancy on my system:
All the Nvidia drivers, except for nvidia-331-updates, are described as "open source". However, nvidia-331-updates is described as "proprietary". Why are these drivers open source, when I thought that all official Nvidia drivers would be proprietary, and only Nouveau would be open source?
This appears to be a bug with drivers added from a PPA. Note, again, that the nvidia-370 driver is listed as "open-source" even though it's very much not. This is because my driver comes from a PPA, and apparently didn't have the attached metadata (or similar) that marked the as proprietary. The only open-source driver is the actual Nouveau driver.

nvidia-driver-390 and nvidia-driver-430 are proprietary Nvidia graphics drivers either of which can be installed from the default Ubuntu 18.04 repositories. Nvidia 390 driver and Nvidia 430 driver are also marked as proprietary not open source drivers in my Ubuntu 18.04 Additional Drivers tab of Software & Updates. Nvidia 440 driver (nvidia-driver-440) comes from ppa:graphics-drivers/ppa which also has nvidia-driver-390, nvidia-driver-410, nvidia-driver-415, nvidia-driver-430 and nvidia-driver-435.
I don't have any Nvidia PPAs enabled in my software sources, so I assume that both Nvidia 390 driver and Nvidia 430 driver are identified as proprietary is the default in Ubuntu 18.04. In the case of nvidia-driver-430 this package is identified as Copied from ubuntu bionic in Primary Archive for Ubuntu in the PPA however it is also identified as open source in Additional Drivers while the default repository nvidia-driver-430 package is identified as proprietary in Additional Drivers. If both of these drivers were created from the same source, they both should be identified as proprietary drivers instead of one driver being identified as open source and the other driver identified as proprietary.
The recommended proprietary Nvidia graphics driver for your computer's graphics processor can be installed from the terminal with the following commands:
When installing a proprietary graphics driver, it is not necessary to uninstall the built-in Nouveau open source graphics driver. The two graphics drivers can be installed alongside each other allowing the open source graphics driver to be used as a fallback alternative in case there is a problem using the proprietary graphics driver.
The
ubuntu-drivers autoinstallcommand installs drivers that are appropriate for automatic installation including their dependencies, and the Nvidia driver will also be updated automatically when an update is available.
