After upgrading from 455.45.01 to 460.32.03, I get a black screen after loading of
nvidia-modeset: First, the screen goes black, then the backlight is toggled several times (about 10 times), finally it stays blank and dark.
Kernel log contains:

Downgrading back to 455.45.01 fixes this. I observe the same with 460.27.04.
Since 460.32.03 is now released as stable and contains critical security fixes, I’m raising this as a new issue, though it is likely the same as already reported in:

As usual, I had to kill
vulkaninfo which did hang in terminal mode otherwise.
