I have a keyboard Logi k600. I use Solaar app but it does not find my keyboard. I use a wireless USB which it has the keyboard.
It does not work neither by wireless USB nor by Bluetooth.
I use Xubuntu:
NAME="Ubuntu" VERSION="20.04.3 LTS (Focal Fossa)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 20.04.3 LTS" VERSION_ID="20.04" HOME_URL="https://www.ubuntu.com/" SUPPORT_URL="https://help.ubuntu.com/" BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/" PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy" VERSION_CODENAME=focal UBUNTU_CODENAME=focal
The setting for Ubuntu should be the same as for Windows:
- Press FN+7 for 3 seconds
- The LED on the 1 key should light up for 5 seconds
