How about this?
1. acpi_backlight=native

2. acpi_backlight=video
I'll try but from all the other posts, that usually results in: native - acpi_video0 (present but doesn't provide backlight control) video - acpi_video0 (not present) vendor - acpi_video0 (not present) I'll report back with TW results, but suspect I won't find anything different. *** Second Post Reply ***

I hope this is not the case.

I hope you are right, but if I recall from the 2016 issue, it was ultimately fixed in discussions between the openSUSE Nvidia contact and Nvidia - which points to a possible issue in their secret part. Though for the G04 driver -- it would have to be a regression in the common code that goes into their blob as this driver doesn't change any more and is considered legacy. -- David C.
