Ambient Light Sensor and backlit keyboard


I am new to Linux OS but I am very excited to use it. I installed Ubuntu on my laptop but the problem was that I have ambient light sensor on my laptop and back lit light. They were not working correctly in Ubuntu OS. I am looking forward to Opensuse but I am skeptical if it will support light sensor or not. Can anyone please let me know if light sensors and keyboard backlit lights are supported in Opensuse? I have Sony Vaio VPCF111FX.

it is not so much does openSUSE support the Sony, but rather it is: does
Sony provide a linux driver? and, i guess the answer to that is no (look
at the box your machine came in: Does it have a Tux Penguin on it, or
just a broken Window)…

but, you can try using either of these as Boot Options and see if it helps:


try the first one alone first, if that works stop adding; if it does not
work try the other alone, if that works stop; if it does not try both…

my guess is if either of those work on openSUSE it will also work on
Ubuntu, so if you already have Ubuntu loaded just try it there…

anyway, you can always try openSUSE by downloading a Live CD, boot from
it and try it that way…and, you also add the above boot options as
you boot the CD…if the backlight does not work as you expect with
the live CD it is unlikely to work ‘out of the box’ once installed…

openSUSE®, the “German Engineered Automobiles” of operating systems!

Nope none of them helped. I tried both of them individually and together but it doesn’t work in opensuse (live cd). I have installed ubuntu 11.10 after reading one of the post which says this issue is fixed in it. But backlit keyboard doesn’t work at all. Please help.

sorry i just noticed how new you are to these fora, so -=WELCOME=- new

it might be that that hardware is not provided with a means to control
the backlight by any operating system other than the one it was sold with…

i’m not familiar with that particular Sony Vaio which you have, but i do
know that there are many problems trying to get them to perform
wonderfully with Linux…

i’m not saying it is impossible, but it might not be possible for a year
or two when the Linux developers are finally able to figure out how it
is controlled in Windows (and, you can bet that neither the Sony nor MS
engineers who worked together (to allow the hardware light to be
software controlled) won’t be sharing the ‘secrets’ with the Linux

if you want a Linux notebook it best to buy one known to work with Linux…
