Kernel 6.2.0-35 works fine. Its a elder MacBook Air with a core2duo running nvidia geforce 320m graphics card using the nouveau driver. attaching a "nomodeset" to the kernel command line makes the screen work again on the 6.2.0-36 kernel, but disables all the power stuff of the gfx card including brightness control and related things. not a permanent solution. as said, picture attached. system is lubuntu based on 22.04.3 lts. best regards K.
