Logitech G910 keyboard gkey support for GNU/Linux (Project version: v0.2.4)

Because I didn't find any GKey support for Logitech G910 keyboard I decided to create this GKey mapper. Code is based on an issue in g910-gkey-uinput project. I expanded the code, so that it is more user friendly to add functionality to GKeys.

The code is tested on Logitech G910 keyboard, OS: Manjaro, 4.19.1 Linux kernel, DE: kde plasma 5.14.3.

Everything is described in great depth (and actually much better) on WIKI.

Note: From version 0.2.0 onwards the g810-led controller is no longer required because Gkey to Fkey mapping is disabled inside the driver.

Requirements

To use this project you need:

  • Python >=3.7
  • git
  • g810-led controller
  • uinput kernel module (more on this here)
  • pip requirements are stored in requirements.txt

Installation [AUR]

  • install g810-led-git for your distro (for Arch based distros: aur)
  • disable Gkeys to Fkeys mapping: g910-led -gkm 1 (probably will include that on program start)
  • load uinput kernel module: modprobe uinput (on Manjaro is loaded by default afaik)
  • clone repo: git clone https://github.com/JSubelj/g910-gkey-macro-support.git
  • move to cloned repo: cd g910-gkey-macro-support
  • run the installer shell: chmod +x installer.sh; sudo ./installer.sh
  • This will install the module and set a command g910-gkeys, add a service file to /usr/lib/systemd/system/g910-gkeys.service and reload systemd daemon
  • start the daemon: systemctl start g910-gkeys
  • you can also add it to start on startup: systemctl enable g910-gkeys

Uninstalling

  • Uninstalling can be done with files.txt that was created on install (if you deleted it you can always run the installer again to create it)
  • run command: cat files.txt | sudo xargs rm -rf
  • list pip packages that include g910: pip list | grep g910
  • remove the ones that concern this driver: pip uninstall ${pkgs to uninstall}
  • it is also recommended to disable the service: systemctl disable g910-gkeys
  • and remove it from system folder: rm /usr/lib/systemd/system/g910-gkeys.service
  • you can also delete the configuration: rm /etc/g910-gkeys -rf

Configuration

Configuration should be located in /etc/g910-gkeys/config.json and should be syntactically correct. Example configuration can be found in docs folder: ex_config. Currently the mapper supports three types of hotkeys (also described in hotkey_types.txt):

  • "typeout" - Type out (ex. clicking on GKey types out a string)
  • "shortcut" - Shortcuts (ex. clicking on GKey presses shift+f4)
  • "run" - Starting a program (anything you can start from shell) This works only on cli programs (see why: Why can't I run graphic programs by default).
  • "nothing" - Do nothing (unbound key)

To add a hotkey add to config.json the following code:

"g<no_of_gkey>": {
    "hotkey_type": <type of command "nothing" or "typeout" or "shortcut" or "run">,
    "do": "<thing to do>"
  }

Depending on the hotkey command, the syntax for "do" is different (supported characters for typeout and hotkeys are listed in supported_keys.txt):

  • "typeout" - Typeout syntax is same as you would type text out (ex. "tyPe Me Out!")
  • "shortcut" - Shortcuts are separated by a plus sign and a comma (ex. "ctrl+c,ctrl+v")
  • "nothing" - If hotkey_type is set to "nothing" then "do" key need not exist or can be anything.
  • "run" - Run has the same syntax as you would type a cli program in command line (ex. "systemctl daemon-reload")
