Thanks Simon, Looks like the KBCL variable is indeed the right one. Strange that it changed from 01 to 04 rather than 01 to 05 though... If you have time for a few more tests, I would love to know what values it takes when the UEFI variable is modified from 00 through 07.
Currently we have: UEFI KBCL 00 01 01 02 03 04 05 04 06 07 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
