Through a quick glance, I couldn't spot out the suspicious changes. There have been a few changes in drivers/acpi/video_detect.c, but acpi_backlight=native behavior should be kept, and there is no significant change in nouveau's backlight code, either. Maybe it's about the probing of the nouveau itself; please boot with "drm.debug=0x1e log_buf_len=1M" options and get the dmesg output for both working and non-working cases. Last but not least, please give hwinfo output, too. -- You are receiving this mail because: You are the assignee for the bug.

Created attachment 865555 [details] output of dmesg with non-functioning (current) kernel (6.2.4-1-default)

Unfortunately, the interesting part was already discarded. Could you take the log a bit earlier (so that it fits) or extend the log size from 1M to 16M or such? If the size matters, you can compress the file at uploading, too. -- You are receiving this mail because: You are the assignee for the bug.
