Bug Description
Hi,
after updating a (lubuntu) system from 6.2.0-35 to 6.2.0-36 kernel, the entire screen turn into a unusable flickering color puzzle. not sure what exactly the root cause for this is. possible wrong refresh rate/resolution detected by the kernel? doing input like switching blindely to a virtual console and doing a login blindely following a poweroff works fine. input isnt affacted at all as long as you can type virtually blind on a color puzzled console. a picture is attached. 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.
