| [ Upstream commit b3f2f3799a972d3863d0fdc2ab6287aef6ca631f ] |
| |
| When the OS registers to handle events from the display off hotkey the |
| EC will send a notification with 0x35 for every key press, independent |
| of the backlight state. |
| |
| The behavior of this key on Windows, with the ATKACPI driver from Asus |
| installed, is turning off the backlight of all connected displays with a |
| fading effect, and any cursor input or key press turning the backlight |
| back on. The key press or cursor input that wakes up the display is also |
| passed through to the application under the cursor or under focus. |
| |
| The key that matches this behavior the closest is KEY_SCREENLOCK. |
