Kieran's solution doesn't work for me on Xubuntu 15.10 (900X3E). I can edit the values with xxd -p /sys/firmware/efi/efivars/KBDBacklitLvl-8be4df61-93ca-11d2-aa0d-00e098032b8c
but they have no effect. Any ideas what else to try? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1203592/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
