 |
|
Im doing power managment on my laptop and using laptop-mode-tools per wiki guidelines I get the following error:
| Code: | # rc-config restart laptop_mode
Restarting init script
laptop_mode | * Stopping laptop_mode ...
laptop_mode |Cannot find device "eth0"
laptop_mode |command failed: Operation not supported (-95)
laptop_mode |Failed to set power saving mode for wireless card [ ok ]
laptop_mode | * Starting laptop_mode ...
laptop_mode |Cannot find device "eth0"
laptop_mode |command failed: Operation not supported (-95)
laptop_mode |Failed to set power saving mode for wireless card [ ok ] |
apparently network adapter names aren't found and I tried to locate them in laptop-mode-tools configuration files in /etc/laptop-mode/conf.d/ but found nothing, I hope this can be fixed. |

Hello,
the error about the network adapter not found is a known issue, the reason is that the device name is hard-coded in the default configuration file.
Just edit /etc/laptop-mode/conf.d/ethernet.conf file and set ETHERNET_DEVICES with the appropriate device name. It even accepts a list of devices, if needed.
For example
| Code: | | ETHERNET_DEVICES="enp5s0" |
You may want to take a look at the Arch Wiki page which is pretty good. |

To get rid of the error about failing to set power saving mode for wireless card (since your card, like mine, doesn't support this operation), you can just disable this module.
Edit /etc/laptop-mode/conf.d/wireless-power.conf and set | Code: | | CONTROL_WIRELESS_POWER_SAVING="0" |
