hansdegoedeA while ago as a spin-off of my project to improve support for Logitech wireless keyboards and mice I have also done some work on improving support for (Gaming) keyboards with a builtin LCD panel.
Specifically if you have a Logitech MX5000, G15, G15 v2 or G510 and you want the LCD panel to show something somewhat useful then on Fedora 31 you can now install the lcdproc package and it will automatically recognize the keyboard and show "top" like information on it. No need to manually write an LCDd.conf or anything, this works fully plug and play:
sudo dnf install lcdproc
sudo udevadm trigger
If you have a MX5000 and you do not want the LCD panel to show "top" like info, you may still want to install the mx5000tools package, this will automatically send the system time to the keyboard, after which it will display the time.
Once the 5.5 kernel becomes available as an update for Fedora you will also be able to use the keys surrounding the LCD panel to control the lcdproc menu-s on the LCD panel. The 5.5 kernel will also export key backlight brightness control through the standardized /sys/class/leds API, so that you can control it from e.g. the GNOME control-center's power-settings and you get a nice OSD when toggling the brightnesslevel using the key on the keyboard.
The 5.5 kernel will also make the "G" keys send standard input-events (evdev events), once userspace support for the new key-codes these send has landed, this will allow e.g. binding them to actions in GNOME control-center's keyboard-settings. But only under Wayland as the new keycodes are > 255 and X11 does not support this.
