description |
Backlight hotkeys are registered and OSD shows backlight level going up and down but there is no effect on actual backlight level.
Following the debugging instructions here: <https://wiki.ubuntu.com/Kernel/Debugging/Backlight>, I have added the kernel boot parameter "acpi_backlight=vendor" and this makes the backlight work as expected.

SRU Justification:
Impact:
Backlight hotkeys are registered and OSD shows backlight level going up and down but there is no effect on actual backlight level.
Fix:
Apply a system specific quirk to the kernel for this model.
Testing:
TBD
Following the debugging instructions here: <https://wiki.ubuntu.com/Kernel/Debugging/Backlight>, I have added the kernel boot parameter "acpi_backlight=vendor" and this makes the backlight work as expected.
