I have a Toshiba Satellite p755-s5260 with the LED backlit keyboard with shortcut keys above the keyboard that are also supposed to light up. The LED's are enabled in the BIOS and work up until Ubuntu boots up. Any suggestions?

Basically use xset to toggle the state of the led backlight. A little script and your set.

if [ -f /tmp/keyboard_light ]; then
xset -led 3 && rm /tmp/keyboard_light
xset led 3 && touch /tmp/keyboard_light

or use "key touch" Download Here

This can configure ALL your special keys.

I have a toshiba satellite s5265, with the same issues as you and this is how I managed to make my keyboard light up: I booted up a windows install dvd and on the install screen, i pressed the backlight key on top of the keyboard (looks like a square with an arrow inside) just once. When I rebooted, the keyboard backlight stayed on throughout. Hopefully this will help you and others.

I will be ready to answer any questions you have

Don't put any disks in at all. Just press the backlight key on top of the keyboard (looks like a square with an arrow inside) just once. It is above F9. It should work.

My laptop is a Toshiba p745 and I dual-boot Ubuntu and Windows. My keyboard backlight does not work when I boot Ubuntu. However, I can suddenly make it work when I log on to Windows in safe mode and shutdown immediately.

Please ask your own question, this one is from 2011 and this is a Q&A site not a forum, this space is for answers. – mark kirby Nov 5 at 18:05
@markkirby: This is an actual answer! (read again: only works for dual-boot and not very clear, but it is an answer!) ;-) – Fabby Nov 6 at 0:40
