NVIDIA have release two new drivers over the last day! An update to their Vulkan beta driver as well as a new stable driver update for everyone.
Firstly their Vulkan beta driver, the special branch they use for testing new Vulkan API bits and more, has been rebased onto 435.17. They also mentioned that 8-bit integer support has been added to the VK_NV_cooperative_matrix extension and performance improvements have been taken from the 435.17 series.
Additionally, the bigger one here is the new 435.21 stable driver. This is almost the same as the recent beta release of 435.17, which is the update that finally brings in support for PRIME render offload. However, they also noted one extra bug fix over the beta "Fixed a bug that caused the X server to crash when using HardDPMS with an NVIDIA-driven GPU Screen.".
The 435.21 driver is part of their "Short Lived" series as opposed to the current "Long Lived" series at 430.40.
Confused on the difference? Here's what NVIDIA themselves said about it (source):
Article taken from GamingOnLinux.com.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 made from each branch. A short-lived branch typically has only one or two (non-beta) releases, while long-lived branches will have several.
^_^
At the same time, it's not apparent how big the jump from, say, 430.40 to 435.21 would be, as there is no way to tell how many releases have been made in between. Could be none, could be half a dozen.
Anyone has any insight to share what those numbers actually represent? Is there any logic behind it?
435.19.02 vulkan beta driver is based on the same 435.17 also but adds some vulkan stuff on top and doesnt have the 435.21 xorg crash fix. while 435.21 doesnt have the extra vulkan stuff the 435.19.02 adds
430.40 is completely older branch. 435.21 has lots of new additions over this
basically first number is the major version, 410,418,430,435 - those include major additions.
second number is the fixes number - fixes and minor features on top of the major branch
third number (only for vulkan beta testing) - has extra vulkan testing extensions or fixes that will later be merged into next major number of stable drivers

You may also need to remove the line 12 (PrimaryGPU thing) in:
/usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.confAnd it works pretty well! I'm very happy to have such a feature available right in the driver.

Now I absolutely refuse to reset systemctl back to graphical because I know it's broken and it will be a PITA. So I'm on CentOS until I figure this out.
EDIT: Yep, a compiler mismatch.
