Hello, everyone.
This issue is 100% reproducible, and is present at least since kernel 5.15, both with open, and with binary modules.
When both nvidia and intel modules are loaded, certain operations soft-freeze the system for a few seconds. Such operations include running wine, or just running xrandr -display $DPY --verbose
GPU: RTX 4000 TU104
Intel UHD Graphics 630
dmesg is full with:
[ 5824.755664] i915 0000:00:02.0: [drm] *ERROR* Failed to probe lspcon
[ 5824.755665] i915 0000:00:02.0: [drm] *ERROR* LSPCON init failed on port D
The issue is described quite extensively here:
I am attaching the “nvidia-bug-report”

I am not fully convinced this is Nvidia’s responsibility, because the open kernel should do little more than nothing in the kernel space, and there are issues with LSPCON’s implementation on the Intel’s side, but I would like to keep this thread here for reference, because, after all, I paid for both graphics cards, and it would be nice if those two could cooperate instead of fighting.
