A: Turn off keyboard back-light Sony (VAIO SVF1521DCXW)

Try downloading the Vaio Control Center from SourceForge. To install it, run the following steps: Open a terminal cd ~/Downloads mkdir ~/.VCC mv vaio-control-center-0.1.tar.bz2 ~/.VCC cd ~/.VCC tar -xjvf vaio-control-center-0.1.tar.bz2 make -j12 chmod +x vaio-control-center ./vaio-control-cent...

If the above does not work, omit the -j12 on the make command.

Same error after step 7 with make -j12 or make: make: *** No rule to make target '/usr/share/qt/mkspecs/linux-g++-64/qmake.conf', needed by 'Makefile'. Stop.

I make a symbolic link to gt4 by ln -s qt4 qt and then try with your suggestion, now when I use make I get this error: "WARNING: TARGET is empty make: Nothing to be done for 'first'. "

@KasiyA Try forcing make. Use make -j12 -B

No' still same error.

@KasiyA Do you have the vaio-control-center file? If so, run that baby.

4:47 AM

Not running. this error: bash: ./vaio-control-center: No such file or directory

@KasiaY Try redownloading into a clean folder?

@KasiyA If the executable exists, try that before compiling. You may have to chmod it.

running with vaio-control-center I get this error vaio-control-center: command not found. with ./vaio-control-center I get this error.

@KasiyA Did you forget the ./ ?

see Above comment.

Have you tried to do chmod it? Also, are you SURE you're in the right dir?

4:49 AM

yes I run chmod +x vaio-contol-center in right dir.

hmm.

and it shows "no file"?

actually yes. here is output of ls:

Have you tried the absolute path of the file yet?

compile Makefile run vaio-control-center vcc
COPYING moc_main_window.cpp ui_main_window.h vaio-control-center.pro

wait what??

./compile

4:53 AM

the content of `compile` file is "#!/bin/sh

make -j12"

Also, you can try following this answer: askubuntu.com/a/492455/208574

It might help.

It's also my question and it's not working also with that solution

hmmm.

this is an odd problem.

hang on. let me get a new download link

here is the output of trying above answer

user@user-pc:~$ cd /home/user/Downloads/vaio-control-center-0.1
user@user-pc:~/Downloads/vaio-control-center-0.1$ /usr/lib/i386-linux-gnu/qt4/bin/qmake -o Makefile vaio-control-center.pro
bash: /usr/lib/i386-linux-gnu/qt4/bin/qmake: No such file or directory

user@user-pc:~/Downloads/vaio-control-center-0.1$ /usr/share/qt4/bin/qmake -o Makefile vaio-control-center.prouser@user-pc:~/Downloads/vaio-control-center-0.1$ make
make: *** No targets specified and no makefile found. Stop.

umm.

just try qmake

But, what I think should be done is this:

Scrap the old file and re-download from here: sourceforge.net/projects/vaio-control-ce/files/latest/download

5:00 AM

with `qmake`

user@user-pc:~$ cd /home/user/Downloads/vaio-control-center-0.1
user@user-pc:~/Downloads/vaio-control-center-0.1$ /usr/share/qt4/bin/qmake -o Makefile vaio-control-center.pro
user@user-pc:~/Downloads/vaio-control-center-0.1$ qmake
WARNING: TARGET is empty

user@user-pc:~/Downloads/vaio-control-center-0.1$

qmake first, and then make

so, qmake -o Makefile vaio-control-center.pro followed by make

But if the file already exists, try just running it, after chmodding it.

qmake then make

user@user-pc:~/Downloads/vaio-control-center-0.1$ qmake
WARNING: TARGET is empty
user@user-pc:~/Downloads/vaio-control-center-0.1$ make
make: Nothing to be done for `first'.

yesh.

like i said, try re-downloading.

I download it again

user@user-pc:~/Downloads/vaio-control-center-0.1$ chmod +x vaio-control-center.pro
user@user-pc:~/Downloads/vaio-control-center-0.1$ chmod +x vaio-control-center
user@user-pc:~/Downloads/vaio-control-center-0.1$ ./vaio-control-center
bash: ./vaio-control-center: No such file or directory
user@user-pc:~/Downloads/vaio-control-center-0.1$ ./vaio-control-center.pro
./vaio-control-center.pro: line 5: TEMPLATE: command not found
./vaio-control-center.pro: line 6: TARGET: command not found

sudo chmod 777 vaio-control-center?

5:08 AM

user@user-pc:~/Downloads/vaio-control-center-0.1$ chmod 777 vaio-control-center
user@user-pc:~/Downloads/vaio-control-center-0.1$ ./vaio-control-center
bash: ./vaio-control-center: No such file or directory

try running it as sudo.

I don't think it's even readable.

user@user-pc:~/Downloads/vaio-control-center-0.1$ sudo chmod 777 vaio-control-center
[sudo] password for user:
user@user-pc:~/Downloads/vaio-control-center-0.1$ ./vaio-control-center

sudo: unable to execute ./vaio-control-center: No such file or directory
user@user-pc:~/Downloads/vaio-control-center-0.1$

what the...

can you do `ls' please?

user@user-pc:~/Downloads/vaio-control-center-0.1$ ls
compile Makefile run vaio-control-center vcc
COPYING moc_main_window.cpp ui_main_window.h vaio-control-center.pro

./vcc ?

5:13 AM

it's a folder :

user@user-pc:~$ cd /home/user/Downloads/vaio-control-center-0.1
user@user-pc:~/Downloads/vaio-control-center-0.1$ cd vcc
user@user-pc:~/Downloads/vaio-control-center-0.1/vcc$ ls
helpers.c helpers.h main_window.cpp main_window.hpp main_window.ui vaio-control-center.cpp
user@user-pc:~/Downloads/vaio-control-center-0.1/vcc$

hmm.

try make in the main dir.

user@user-pc:~$ cd /home/user/Downloads/vaio-control-center-0.1
user@user-pc:~/Downloads/vaio-control-center-0.1$ make
make: Nothing to be done for `first'.
user@user-pc:~/Downloads/vaio-control-center-0.1$

hmmm.

this is STRANGE.

try /home/user/Downloads/vaio-control-center-0.1/va <kbd>TAB</kbd>

feh. Try tabbing to autocomplete.

I think it might have a special character in it.

user@user-pc:~/Downloads/vaio-control-center-0.1$ validlocale

whaaat?

hmm.

Can you run file vaio-control-center and give me the output?

5:18 AM

I don't know but when I type va and then I hit <Tab>, it show

OH.

type ./va and hit tab

Also, are you 32bit or 64bit?

I'm 64 bit os and also 64bit arch
output of typing `./va` and hitting <tab> : ./vaio-control-center

yes!

hit enter on that puppy.

bash: ./vaio-control-center: No such file or directory

...

run file vaio-control-center please.

5:23 AM

From running in nautilus nothing happens and from terminal I get error:
bash: ./vaio-control-center: No such file or directory

seems so.

Again, can I have the output of file vaio-control-center please?

user@user-pc:~/Downloads/vaio-control-center-0.1$ vaio-control-center
vaio-control-center: command not found
user@user-pc:~/Downloads/vaio-control-center-0.1$

5:35 AM

no out put And NOW...

afk for a couple secs

WT??

back. sorry.

I assume that "WT??" is good.

hey (boy/girl):
user@user-pc:~/Downloads/vaio-control-center-0.1$ ./vaio-control-center
open_file: can't open /sys/devices/platform/sony-laptop/battery_charge_limiter: No such file or directory
user@user-pc:~/Downloads/vaio-control-center-0.1$

ah. PROGRESS :D

can you run ls /sys/devices/platform/sony-laptop?

5:40 AM

user@user-pc:~$ ls /sys/devices/platform/sony-laptop
battery_care_health battery_care_limiter driver modalias power subsystem touchpad uevent
user@user-pc:~$

oh geez.

one second please.

we at least made lots of progress.

thank you so much...

Still not there, but you can run the file.

While I am looking at the code, let me explain how we got that file to run.

ok. thanks

The system was looking for a library that was not existent.

When you symlinked, it made the file "exist"

thus, it worked. The "file not found" was referring to a LIBRARY, not the program.

Bash needs better error messages.

woo. i love finding code.

one second.

5:47 AM

I only see the screen... :D

uh-oh.

one second...

run this please: sudo rmmod -v sony-laptop; sudo modprobe -v sony-laptop kbd_backlight=0

i want to try something real fast

nothing happened

ls /sys/devices/platform/sony-laptop again please?

battery_care_health battery_care_limiter driver modalias power subsystem touchpad uevent

still no change

odd.

5:54 AM

yes no change

what version kernel do you have?

3.13.0-34-generic

is there an update to that available?

it's latest

hm.

it appears like your kernel driver doesn't like detecting things or doing keyboard things.

try echo 0 > /sys/devices/platform/sony-laptop/kbd_backlight. I know the file doesn't exist. Just try it.

5:59 AM

bash: /sys/devices/platform/sony-laptop/kbd_backlight: No such file or directory

okay.

Umm, tee 1 /sys/devices/platform/sony-laptop/kbd_backlight

oops.

tee: /sys/devices/platform/sony-laptop/kbd_backlight: No such file or directory

and cursor blinking _

ctrl+c

The problem is that vaio-control-center needs the kbd_backlight file to work.

DING

user@user-pc:~$ tee 1 /sys/devices/platform/sony-laptop/kbd_backlight
tee: /sys/devices/platform/sony-laptop/kbd_backlight: No such file or directory
^C
user@user-pc:~$

Reboot and go into grub. Edit the Ubuntu boot entry and add sony_laptop.kbd_backlight=0 after the splash command in the Kernel line.

Post back results when done please.

6:03 AM

ok

nothing and nothing

aww.

try again with acpi=force.

acpi=force and sony_laptop.kbd_backlight=0 or just acpi=force?

just acpi force

ok

anything change?

6:16 AM

no

um, try sudo rmmod -v sony-laptop; sudo modprobe -v sony-laptop kbd_backlight=0 again

no out put no error

hmmm.

ooow wait:
this result is showed
insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=0 kbd_backlight=1 kbd_backlight_timeout=0 kbd_backlight=0

hmmm.

that's interesting. Any change in backlight?

6:18 AM

no

ls /sys/devices/platform/sony-laptop/ please?

Also try the sudo variant of the above command.

user@user-pc:~$ ls /sys/devices/platform/sony-laptop/
battery_care_health battery_care_limiter driver modalias power subsystem touchpad uevent
user@user-pc:~$ sudo ls /sys/devices/platform/sony-laptop/
[sudo] password for user:
battery_care_health battery_care_limiter driver modalias power subsystem touchpad uevent
user@user-pc:~$

aww. no change.

still No changes

try ls /sys/class/ | grep keyboard

6:23 AM

no output

try sudo rmmod -v sony-laptop; sudo modprobe -v sony-laptop

and give me output

insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=0 kbd_backlight=1 kbd_backlight_timeout=0

ooooo!

Can you paste the output of cat /etc/modprobe.d/options.conf?

we're getting close!

options sony_laptop kbd_backlight=0

that's it?

6:27 AM

Yes

Delete that line please.

ok

and run sudo rmmod -v sony-laptop; sudo modprobe -v sony-laptop again please.

Paste any output.

insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=1 kbd_backlight_timeout=0

a-ha!

kbd_backlight=1

THAT IS WHAT IS KEEPING BACKLIGHT ON!

6:30 AM

How we can fix to turn off?

i'm looking it up

I tried with " sudo modprobe -v sony_laptop kbd_backlight=0" but still kbd_backlight=1 in this output

insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=1 kbd_backlight_timeout=0 kbd_backlight=0

i know.

looking up data now.

It's NOT set in the kernel code itself.

There is some config file SOMEWHERE doing that.

Run ls /etc/modprobe.d please.

it'll be a long output

alsa-base.conf blacklist-framebuffer.conf blacklist-rare-network.conf mlx4.conf sony-laptop.conf
blacklist-ath_pci.conf blacklist-modem.conf blacklist-watchdog.conf new vmwgfx-fbdev.conf
blacklist-bcm43.conf blacklist-nouveau.conf dkms.conf nouveau-kms.conf
blacklist.conf blacklist-nouveau.conf~ fbdev-blacklist.conf options.conf
blacklist-firewire.conf blacklist-oss.conf iwlwifi.conf options.conf~

cat /etc/modprobe.d/sony-laptop.conf please.

We are getting REALLY CLOSE.

6:38 AM

options sony-laptop kbd_backlight=1 kbd_backlight_timeout=0

YES

YESYESYESYESYES

Delete that line.

I have deleted And Nowwwwwwwww

One more: sudo rmmod -v sony-laptop; sudo modprobe -v sony-laptop

insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko

BA-DOOM!

sudo rmmod -v sony-laptop; sudo modprobe -v sony-laptop kbd_backlight=0

6:41 AM

No change :(

what, really?

is not need to restart?

any output?

insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=0

okay...

One more please.

cat /etc/modules | grep 'sony-laptop'

6:43 AM

no output

i updated the command

are you sure it was cat and not ls?

i made a typo. sorry.

Yes I am sure.

cat /etc/modules | grep sony-laptop

no output

cat /etc/modules?

6:45 AM

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.

lp
rtc

okay.

Run sudo update-initramfs -u followed by a reboot.

dont add any boot time parameters.

update-initramfs: Generating /boot/initrd.img-3.13.0-34-generic

and now I need to reboot?

yes

ping me when you're back.

Sorry to late. no change. sony-laptop.conf file is empty!

okay. wonderful.

that is actually good.

Now, run sudo rmmod -v sony-laptop; sudo modprobe -v sony-laptop kbd_backlight=0 again.

We are soooo very close now.

6:56 AM

insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=0

okay, no change?

no change.

well, we are making progress.

ummmm...

ls /sys/devices/platform/sony-laptop/

battery_care_health battery_care_limiter driver modalias power subsystem touchpad uevent

awe.

Okay. Try rebooting with acpi=force and running sudo rmmod -v sony-laptop; sudo modprobe -v sony-laptop kbd_backlight=0.

7:01 AM

exactly how can i reboot with acpi=force?

reboot, go into grub editor, and add acpi=force after the splash but before the '

output:

insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=0

near 3 hours we are in chat. thank you for helping

no change in keyboard?

no

hmm.

Let's try rebooting but with BOTH sony_laptop.kbd_backlight=0 and acpi=force.

7:15 AM

like this GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force sony_laptop.kbd_backlight=0"

?

yes.

ok

that might be the magic bullet.

doesn't need to run sudo update-initramfs -u

nope.

BUT

you do need to run sudo update-grub

7:17 AM

ok I see you again after reboot

see you!

no change.

awe.

try running sudo rmmod -v sony-laptop; sudo modprobe -v sony-laptop kbd_backlight=0 again.

i can feel that we are getting close.

insmod /lib/modules/3.13.0-34-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=0 kbd_backlight=0

and no change

siigh

um. let's see here.

Is there still no /sys/devices/platform/sony-laptop/kbd_backlight file?

7:24 AM

Yes it's not exist.

meh.

Okay. Plan B

You're going to need duck tape.

Pull off each of the keys, and place duck tape under them.

and give me a second to find something else to try.

hmmm.

Want to try something else?

I don't understand you mean?

In `/etc/modules`, add this line:
`sony-laptop kbd_backlight 0`

and now

run sudo update-initramfs -u

Next, reboot.

7:29 AM

ok

anything?

nothing

awe.

does /sys/devices/platform/sony-laptop/kbd_backlight exist?

no

/me sighs

ohhhh.

Did you edit /etc/default/grub?

7:35 AM

a litile

With the acpi?

and the backlight command?

yes

can you remove both of them please?

'h

when done, sudo update-grub

and reboot please.

7:36 AM

ok

If this doesn't work, I have two more ideas.

then please say one of your two ideas

it's not working

idea one: It's a kernel bug.

and nex one

In which case, you need to report it.

I can help with that.

Idea two: Get duck tape. Pull off the keys and place some tape on the bottoms.

7:40 AM

can I fix that after reporting?

Unfortunately, not immediately.

You need to wait for the bug to be patched.

Another possible idea is that the BIOS just isn't allowing Ubuntu to control stuffs.

there is pach but I don't know how to pach it.

patch? Where?

just wait to give you a link

k.

7:43 AM

I am looking for that. please wait

it is absence.it/vaio-acpi/source/patches

which patch version should I use?

I don't know can you please see here code.google.com/p/vaio-f11-linux/wiki/VaioControlCenter

what kernel are you using again?

3.13.0-34-generic

ok. thanks

Okay.

I think the 3.2.2 patch should work for you.

oh man. you're gonna have a PROBLEM.

sorry.

7:51 AM

Why? what happened?

Two words: Custom Kernel

In other words, in order to get this thing working, you need to build your own kernel.

I am new in Ubuntu :(

Exactly.

I've been working with Ubuntu for 4-5 years, and building a custom kernel is still very hard.

I'm very sorry, but I don't think there's an easy solution for this.

What you SHOULD do is post the bug to Launchpad. Provide all the information you can, as well as this patch.

I just working 3 month with Ubuntu.

However, it might be easy too.

Your BIOS might just not be allowing you to change these settings.

If you want, I can guide you through the steps for creating a bug report.

7:56 AM

I have a dual boot with windows, in windows I have installed Vaio control center and it's work as well but I don't know why I can't find any solution. THANK YOU VERY VERY MUCH

Well, here.

Let me guide you through bug reporting real fast.

Thank you. I don't know how can I thank you. thank you

First off, you want to start at this page: launchpad.net/ubuntu/+source/linux

Click the "Report Bug" link on the right.

In the summary, describe the kernel module (in this case sony-laptop) and a BRIEF title for the problem.

In the main text, explain the bug quickly and efficiently. Also link these resources:

* The AskUbuntu question. This says everything that you did.

* This chat. I've walked you through debugging, and i'm sure the devs will be more than happy to have this info.

* Finally, the patch. This will give them a place to start.

It is important to know that bugs are NOT dealt with immediately. They are dealt in order of importance. If you can, make the bug sound like it's bad. It will get more attention. Don't over-exaggerate though.

Use this link for the chat: chat.stackexchange.com/transcript/16735

thank you. I will report that.

I will also update my answer with the above information.

Once you reported the bug, leave a comment on my question so I can update it.

8:05 AM

Ok thank you again.

There. Posted new answer.

Good luck, and I hope your bug will be resolved soon. I think it will.

You can provide a patch and a detailed record of what you tried.

Take it from me. Devs are lazy. The work is already done. :D

All they need to do is patch the code and place it in the final revision for the next kernel update.

8:25 AM

Well, I'm off for the night.

I hope your problem will be solved soon.

Good luck!!

good night. thanks
