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.
