Subject: [PATCH 2/2] acpi-video: Add disable_native_backlight quirk for
|
|
|
2384fb4 |
Samsung 510R
|
|
|
2384fb4 |
|
|
|
2384fb4 |
Backlight control through the native intel interface does not work properly
|
|
|
2384fb4 |
on the Samsung 510R, where as using the acpi_video interface does work, add
|
|
|
2384fb4 |
a quirk for this.
