[545.23.06] X server don't start

After updating to the new 545.23.06 driver, X server don’t start.
I can start sway and Hyprland from tty, but sddm/plasma fails to start on X11.

OS: CachyOS Linux x86_64
Kernel: 6.5.7-2-cachyos
CPU: Intel(R) Core™ i7-9750H (12) @ 4.z
GPU 1: Intel UHD Graphics 630
GPU 2: NVIDIA GeForce RTX 2060 Mobile

Here follows bug report from tty, after sddm failed to start.

Try using the new frame buffer option, see

no luck with fbdev=1 option.

It looks like the X driver isn’t loading because you’re using a prerelease X server snapshot that isn’t supported:

X.Org X Server
[     5.910] ================ WARNING WARNING WARNING WARNING ================
[     5.910] This server has a video driver ABI version of 26.1 that is not
supported by this NVIDIA driver.  Please check
http://www.nvidia.com/ for driver updates or downgrade to an X
server with a supported driver ABI.
[     5.910] =================================================================

Apart from commit dix: Remove pScratchPixmap and other associated ABI changes (3cb3024f) · Commits · xorg / xserver · GitLab

(which, btw. I reported back then, cf. 525.47.04 hangs during boot with xorg-server-git ),

everything was working fine with X being up to date with master branch.

I want to move 100% to wayland compositors, but every driver release is a hit or miss (specially with PRIME devices) and I end up reverting back to X.

Anyway, I’ll revert to 535.43.13 vulkan driver. I just reported so you may not let it slide to the non-beta version.
