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