Until now, users who had a computer with an NVIDIA graphics card and were using a LTS version of UbuntuLike Ubuntu 18.04, we had to add a repository to install its drivers, just as we would to install third-party software such as PulseEffects. This will no longer be necessary, as Canonical has announced that NVIDIA drivers will be available for all supported LTS versions out of the box, or as they say in English, "out of the box".
This is possible thanks to a StableReleaseUpdate, which allows to keep some applications always updated in Long Term Support releases. Be able to use the NVIDIA drivers This is good news to start with, especially for the world of videogames. In addition to being included in the startup system, the support, reliability and stability will be greater than before. And best of all, this inclusion will be extended to many more distributions.
All Ubuntu-based distributions will benefit
The announcement above explains the benefits of having NVIDIA drivers available from the start: NVIDIA driver updates are packaged and delivered to the update channel -proposed, where it is tested until everything goes correctly. Once everything is verified to be perfect, it becomes available on the channel updates. Another positive point is that we do not have to download / install the driver manually or add a repository that could leave our version of Ubuntu "hanging". Being in the Canonical general repository, it will always be available and ready to go. And what is better, this novelty will be taken advantage of, in addition to the expected Ubuntu flavors (Kubuntu, Lubuntu, Xubuntu, Ubuntu MATE, Ubuntu Budgie, Ubuntu Kylin and Ubuntu Studio), all versions based on the operating system developed by Canonical, among which are Linux Mint or elementary OS.
NVIDIA drivers are already available from the start in Bionic Beaver and soon they will also be in Xenial Xerus (16.04).
Regardless of the kernel you use or do you have to be forcefully with 4.18? Are you with 4.15 as well?
