OK so I don't know what tdekbdledsync is for but that was definitely the problem. I will write a script to kill that then turn on the back light thanks. I will also keep an eye out for any downsides to killing that process.
Thanks all.
tdekbdledsync has the task to synchronize the LED status between the Xserver and the keyboard.
And as a side effect it complete blocks any attempts to manipulate LEDs from software. Including f.e. grp_led option to xkb. Unsynchronized LEDs is a very uncommon problem, i would say much more uncommon than using of grp_led. So starting it should be at least optional.
