laptop energy-saving managment

[alexo]

Hello,
I've checked up and set some config parameters in /usr/local/etc/laptop-mode/laptop-mode.conf

I then executed the manager with the following:

Code: [Select]

tc@alexo:~$ sudo /usr/local/etc/init.d/laptop-mode start
but this message appears on the prompt, leaving the command line busy

Code: [Select]

Unhandled kernel version: 3.16 ('uname -r' = '3.16.6-tinycore')

is there anything that I did not set up?

thank you

[Juanito]

I'd guess that the version in the repo is too old for the tc-6.x kernel?

Hi alexo
Thats an old bug:
http://forum.tinycorelinux.net/index.php?topic=13291.0
According to this, it's just a problem with the script:
http://stevenprc2-blog.blogspot.com/2011/11/ubuntu-1110-fix-for-laptop-mode-utils.html
The patch posted here seems to confirm that:
https://bugs.launchpad.net/ubuntu/+source/laptop-mode-tools/+bug/824643

[alexo]

Thank you for your replies, but now there's another problem:

the file laptop_mode is not in the folder /usr/sbin
but in /tmp/tcloop/laptop-mode-tools/usr/local/sbin

and if I try to modify it as root and save the changes I get the error that the filesystem is read-only.

So I copied the laptop_mode file in /usr/sbin and modified as required, but the same

Unhandled kernel version: 3.16 ('uname -r' = '3.16.6-tinycore') message appears.

how can I solve the problem?

[Juanito]

I have laptop-mode-tools working, I can upload it once the server is back up.

Note that you should copy /tmp/tcloop/laptop-mode-tools/usr/local/sbin/laptop_mode to /usr/local/sbin, make the changes and then things will work.

[alexo]

juanito,
the copy and modifications went well (I had to chmod the /usr/local/share/laptop_tool file to edit it)

Shouldn't be the package manager to do this task for the user?
Now when I start the laptop energy saving mode I get these messages:

Code: [Select]

what are those messages??

[Juanito]

It looks like you need to edit the config file to suit your hardware - i.e. only sdx and no hdx

I uploaded laptop-tools from repo -> ok
Selected to load on boot -> ok
edited /usr/local/etc/laptop-mode/laptop-mode.conf to my needs -> ok
started laptop-mode with

Code: [Select]

sudo /usr/local/etc/init.d/laptop-mode start
...nothing happens

Maybe I'm dumb but even if I have choosen to start laptop-mode on AC power and when lid is closed nothing happens as time passes by or when I close the lid.

I noticed that after reboot changes to laptop-mode.conf are lost so I added it to /opt/.filetool.lst
and to start automatically the tool  after logging in I added

Code: [Select]

/usr/local/etc/init.d/laptop-mode start
in bootlocal.sh

cpu fan is always on and laptop doesn't go in suspend mode.

what's wrong?

[gerald_clark]

Did you also load and start acpid as stated in the info file?

[alexo]

acpid was not running, so I started it.
But laptop mode seems not to work.

This id the output of sudo /usr/local/etc/init.d/laptop-mode status

My laptop is an old Acer Aspire 5315
TC 6.4 is installed on a 2GB USB pen drive
formatted as ext4

no swap partition on the drive

[Juanito]

As far as I remember, if you see this:

Code: [Select]

Laptop Mode Tools is allowed to run: /var/run/laptop-mode-tools/enabled exists.
..things are working.

What happens if you then disconnect from a/c power?

[alexo]

Hi Juanito,

laptop mode seems not to work even on battery usage.
I have found two directories where laptop-tool seem to reside:
/usr/local/etc/laptop-mode, where I set laptop-mode.config to my wishes
and
/tmp/tcloop/laptop-mode-tools/usr/local/share/laptop-mode-tools and its subfolders, where there is no trace of my changes.
I don't know where to put my hands because there are too many folders related to this service.

By the way, I installed xscreensaver and set it to activate the energy saving mode, but it cannot start it.

[Juanito]

The correct location for the laptop-mode-tools config is in /usr/local/etc/laptop-mode - you need to add this to your backup if you want  it to persist across re-boots.

[alexo]

/usr/local/etc/laptop-mode is already in my /opt/.filetool.lst

when I told you that I saw two folders in which exists laptop-tools config file is because one of the two - the one in /usr/local/etc/laptop-mode - is the one that should be correct.
The other config file in /tmp/tcloop/laptop-mode-tools/usr/local/share/laptop-mode-tools/files/laptop-mode differs from the former and there is no way to modify it neither as root.
