The uevent support was initially added to handle systems where pressing a hotkey generates an event (good) but the firmware automatically changes the brightness (bad). I have absolutely no idea why I added BACKLIGHT_UPDATE_SYSFS - BACKLIGHT_UPDATE_HOTKEY solves the problem I was trying to solve. I'm not aware of any userspace that relies on BACKLIGHT_UPDATE_SYSFS. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx ------------------------------------------------------------------------------ Shape the Mobile Experience: Free Subscription Software experts and developers: Be at the forefront of tech innovation.
