>From dmesg:

[    5.387513] thinkpad_acpi: This ThinkPad has standard ACPI backlight
brightness control, supported by the ACPI video driver
[    5.387513] thinkpad_acpi: Disabling thinkpad-acpi brightness events by
default...
[    5.392293] thinkpad_acpi: Standard ACPI backlight interface available, not
loading native one

Maybe it has nothing to do, but just in case, have you tried the
"acpi_backlight=vendor" method?
