NVIDIA slip out a small stable Linux driver update with 455.45.01

By - | Views: 14,195

It seems NVIDIA are no longer reserving the two extra digits in their Linux driver versioning for their special Betas, as a new stable driver is out today as 455.45.01.

Quite a small driver that's just a few bug fixes but nice to see NVIDIA do updates both big and small. Here's what they say has changed in this version:

  • Kernel 5.9 support
  • Fixed a bug in a Vulkan blending optimization that could produce incorrect results. Some of the Vulkan titles affected by this bug were:
    • Life is Strange 2
    • Shadow of the Tomb Raider
  • Fixed an issue that caused Vulkan swapchain creation to fail for full-screen windows when a G-SYNC monitor is connected.

This is part of their "Short Lived" branch, and should be safe for everyone to upgrade to if you're sticking to that. They also have their "Long Lived" branch currently on version 450.80.02 that was released back in September.

Since the difference isn't obvious, here's our usual reminder on what the changes are between their stable driver branches on Linux as explained by NVIDIA: 

Any given release branch is either long-lived or short-lived. The difference is in how long the branch is maintained and how many releases are made from each branch. A short-lived branch typically has only one or two (non-beta) releases, while long-lived branches will have several.
[…]
When we make changes to the driver, we evaluate the oldest branch the change needs to go into. New features go into whatever the latest branch is, while bug fixes go into the older branches and are integrated through the newer branches. So using a short-lived branch doesn’t mean that you miss out on fixes, it just means that you also get the latest features.

I'm curious what this means:

 
Fixed an issue that caused Vulkan swapchain creation to fail for full-screen windows when a G-SYNC monitor is connected.


And how it would affect things in practice.

It has been fixed already! See here. This was posted just now, but strangely, on Arch, CUDA was working on 5.9 for a couple of weeks now (at least for me).

I hope this fixed the issue I have in VR, where there is sometimes a small but noticeable delay. Which I can get rid of by opening the SteamVR dashboard for a moment, but it's still something, that's a bit annoying.

it was fixed in 455.38 iirc

im running the vulkan betas without issues either:

This one fixed a part of a several years issue : https://forums.developer.nvidia.com/t/g-sync-compatibility-with-vulkan/78018/39
So now Kepler generation card (GTX 600/700/Titan series) can launch vulkan games/apps in full-screen without a desktop compositor or with compositor disabled. But... It seems G-SYNC is still not working yet. Maybe one day...
Tested on 455.46.01 (vulkan beta drivers).

CUDA on Arch worked because they disabled the licensing check for Kernel modules as for my knowledge. Nothing which would not be possible on other distros too tbh.

I am just lazy and rather like to complain about things than doing something :D

Edit: Thank you for the tip. It works now like a charm on 5.9 with the stock Kernel :)

Note: it seems after they release it, NVIDIA edited the changelog to note this driver has Kernel 5.9 support. Added it to the article.

I was getting nervous, as I was afraid updating my two Arch boxes will break all possible gaming and cuda capabilities... Just now I've googled "is nvidia cuda working with kernel 5.10 now" and I've landed back here :-D

Will try it out soon.
