toshiba sattelite backlit keyboard settings windows 10

I'd originally tried that and found it worked, but wiped out my Linux installation once when restarting after the hibernate. I've seen reference to using Windows hibernate rather than a power-off for the same purpose. If this happens I'm back to the original state. Once I've done this procedure the backlight continues to operate until I completely shut off power to the laptop (no battery or completely dead battery, no line power). The backlight timeout works properly, too, so if you don't hit a key for the set timespan the light goes out until you do hit another key.

If I restore the original harddrive and boot Windows, then turn off the laptop with the power switch (not going through Windows shutdown), switch back to my SSD and reboot into Linux, the keyboard backlight stays on (so does the Toshiba illumination light, but you can turn this off in the BIOS before booting into Linux without any problem). I replaced the harddrive that came with the system with an SSD containing my Linux installation (currently OpenSuse 12.2). However, you can make it work (at least I can, on my Satellite P750D) with some trickery. The keyboard backlight is initially on when you turn on the laptop (if enabled in BIOS), but if you have ACPI enabled it normally shuts off as soon as you start to boot into Linux (immediately after the GRUB boot screen). Here's some more details on the problem and a hardware workaround.

Meanwhile, the bug is definitely not fixed.
