How can I enable keyboard backlight on Sony Vaio pro with Ubuntu 13.10?



I have already tried setting the bit in /sys/devices/platform/sony-laptop/kbd_backlight with



echo 1 | sudo tee /sys/devices/platform/sony-laptop/kbd_backlight


and when saving the file I can see the bit has changed, but my keyboard still stays off.



Has anyone else had this problem, and found a way to fix this?

          Check also /sys/devices/platform/sony-laptop/kbd_backlight_timeout where:





          • 0(default) = 10 secs


          • 1 = 30 secs,


          • 2 = 60 secs and


          • 3 = unlimited.


          Or possibly use a /etc/modprobe.d/sony-laptop.conf file with:



          options sony-laptop kbd_backlight=2
