 Posted: Fri Oct 19, 2018 3:12 am Post subject: ACPID configuration |
 |
|
Hi, ALL,
On the page there is an example on how one can configure the acpid.
However, I think that the configuration file is incomplete as there is no code for power.bat and all other additional files being used.
Does anybody have a guide on how to set up the acpid?
Thank you. |

ONEEYEMAN ... well, yes, it's an example, and so fine tuning is left as an excercise for the reader/user. Not every machine/install is the same, so there is no one size fits all solution.
So, for example, that /etc/acpid/default.sh is using sys-apps/hprofile (which, incidentally, provides the 'power.bat' profile) but you needn't (and I don't ... as I've written my own scripts for such things).
| ONEEYEMAN wrote: | | Does anybody have a guide on how to set up the acpid? |
'default.sh' is just a shell script that is run on every 'event' (as /etc/acpid/events/default calls it). As it's shell you can have it run a command based on what 'acpid-listen' recieves, those parameters are passed to the script, which then checks if 'group=button', and 'action=power' (for example) and runs whatever that 'case' is set to run. Once you understand that it's not to difficult to have it do whatever you need it to do ... that's all there is to it.
Having said that perhaps what you're looking for is further examples ... and so:
| /etc/acpid/default.sh: | #!/bin/sh
# /etc/acpi/default.sh
# Default acpi script that takes an entry for all actions

group=${1%%/*}

khay,
One question:
In the backlight.sh script backlight_sys_dir is referenced. I don't have this directory.
Is it OK?
Also my laptop is AMD based with the "radeon" card.
In that directory I have 2 symlinks: radeon_bl0 and acpi_video0. I used the first one.
Thank you for the example scripts. |

ONEEYEMAN ... that is specific to "intel_backlight" (so, intel graphics chipset). If you have radeon look for a similar directory, and adjust the script to reflect the path/files.

Look to see that one or other contains 'brightness' and 'max_brightness' (or similarly named files). You may need to modify the script to match whatever file names radeon uses.

khay,
They both do. And so I picked the first one.
Do you have multiple in you dir structure?
Thank you. |

ONEEYEMAN ... no, that may be because I have 'video.use_native_backlight=1' as a kernel parameter.
