>From the discussion in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/971061/comments/130 a few worhtwile considerations:
- It is said that this is caused by "UEFI bug though, since Samsung's special hardware features are disabled in UEFI mode." - It therefore only affects Samsung models running in UEFI mode (which is required for dual booting) I'm trying to track down the UEFI problem. Any relevant information on the status of that is appreciated! -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1203592 Title: Keyboard backlight does not work in Samsung Series 9 NP900X4C Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Bug description: In Ubuntu 13.04, the keyboard backlight does not work in Samsung Series 9 NP900X4C. Adding the FN key mappings as described in https://help.ubuntu.com/community/SamsungSeries9 does show information in the notification area when pressing the keyboard backlight's + and - buttons, but: 1) The notification always identifies the backlight as "full max" 2) It has no effect on the backlight - it's always off When I first installed Ubuntu on this machine (12.10), even though the fn keys never worked I did have intermitent backlight functionality - the light sensor would sometimes work and I'd see light in the keyboard. I dual boot in Windows 8 and backlighting works there, so this is not a hardware issue.
