Logitech G815 Keyboard

 The first impression was: og no a teenager programmed the cycling colors. It was most annoying, just to say it in a civil manner. 

However, I found this Gist: https://gist.github.com/cornernote/a0d1893aa004b8928ec7e94ccd8dd844 

This recipe works on Ubuntu:

Install

sudo apt install -y libhidapi-dev

git clone https://github.com/MatMoul/g810-led.git

cd g810-led

make clean

make bin

sudo make install

Sample Settings

# red

sudo g815-led -dv 046d -dp c33f -tuk 1 -a FF0000

# green

sudo g815-led -dv 046d -dp c33f -tuk 1 -a 00FF00

# blue

sudo g815-led -dv 046d -dp c33f -tuk 1 -a 0000FF

I used the green one as a starting point. Thanx to the developers behind this repo :-) 

How to initiate a keyboard script at boot

The Script

Here is the script, that I've saved as /etc/init.d/keyboard.zsh

#!/bin/zsh

# Keyboard setup at boot

# Logitech G815

# Date: 20231020

g815-led -a ffaa00

If you use bash, the shebang (i.e. the first line of this script) should be: 

#!/bin/bash

Now make the script executable:

chmod a+x /etc/init.d/keyboard.zsh

Execute at startup

The last step is to run the script when the system boots. So:

update-rc.d /etc/init.d/keyboard.zsh defaults

The defaults keyword will run the script per default.

Now the keyboard will have a warm curry color. You can change the color, and get the hexcode for the color by a color picker. The one on Duckduckgo is excellent: https://duckduckgo.com/?q=color+picker&atb=v314-1&ia=answer 

Impression of the Logitech G815

It's a fine keyboard. However the annoying color cycles are stupid. Most of us want a more silent working experience. To this moment I don't get the idea of the G-function buttons. They are next to SHIFT, and this will give a lot of weird misses, like this: 5 4444444444444444448 - yeah this was the kind of accident. Obviously Logitech should have tested the UX of the keyboard on a few users above the teenage segment.

That being said, the feeling of the keyboard is great. I like the click of the buttons. And I like the fact that it is programmable by Linux users - that is if they are not afraid of scripts here and there.

At cold boot the script was NOT executed

In this AskUbuntu thread I found a working solution:

Running crontab -e will allow you to edit your cron.

Adding a line like this to it:

@reboot /path/to/script

will execute that script once your computer boots up.

So I added this to the crontab:

@reboot /etc/init.d/keyboard.zsh

This solution works on my Ubuntu Ubuntu 23.04 x86_64 6.2.0-35-generic system. 

Now I'd like to program the G-keys and the M-keys. 

[SOLVED] Beosound Level - Google Assistant Not Working (again)

 Well, for a while the thing worked like a charm. Today the Assistant did not work any more. This is annoying. The sound quality is fantastic, but the integration with Google is a major problem. 

After a factory reset everything seems to work again. I had to reinstall the Level in the B&O app and in Google's Assistant. 

[SOLVED] Cannot update Chrome on Ubuntu

After update Chrome would not accept the recent version. That's why I used the command line approach. This is what worked for me:

sudo sh -c 'echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'\n\n

sudo apt-get update

sudo apt install google-chrome-stable
