Logitech G815 Keyboard on Ubuntu - First Impressions

6 min read
Hey! Thanks for stopping by! Just a word of warning, this post is almost 4 years old, . If there's technical information in here it's more than likely out of date.

My beloved HAVIT KB395L keyboard left Ctrl key has started cutting out intermittently. As a developer all my coding revolves around that key saving changes and copy pasting.

This means that my code now breaks with a random s in there where I thought I’d saved something, or where I’ve replaced a code block with v. 🙃


When I say beloved that keyboard was just the right mix of mechanical feel without the CLACKITY, CLACKITY, CLACK, CLACK noise of a mechanical keyboard.

Check out this video from TaeKeyboards on the HAVIT KB309L so you can get an idea of the sound of the keys.

The video goes into depth on the switch used for the keyboard which is a low profile Kailh switch, see this section for an explanation of how they work compared to normal switches.

This switch is what I’ve been looking for, ever since getting the HAVIT KB395L and finding that keyboards with this switch are very hard to come by.

The new shiny

Ok, time to stop ruminating on the keyboard (as it’s not healthy)! Time to move on, but where to? I mentioned earlier I’ve bee finding it really difficult to find those switches in any other keyboards anywhere.

Well, in these sorts of situations I’ll go where I always go, YouTube! After searching for loads of low profile boards I kept coming across the Logitech G815, the switches looked similar and from watching videos of review on it they sounded similar too.

At £140 it wasn’t a decision I’d make lightly (reduced from £170 though!) but the left Ctrl key situation was quite disruptive to my flow so I had to go in!

I know the next shipment of the HAVIT KB395L will be arriving in November with an increased price tag now, from £85 what I initially paid to £137 as they know they’re onto a winner with this and it’s popularity.

First Impressions

The box for the board was LARGE! Then getting the actual board out of the box I understand why.

Comparison with the HAVIT box on top on the G815 box:

box comparison

They keycaps have a nice matt finish, time will tell on how long it will be before the finish wears off to leave shiny buttons. I’m fine with that by the way.

The buttons for the presets at the top, along with the brightness switch and game mode switch add a good 25mm to the top of the board.

That along with the G switches on the left of the board all add up to quite a larger footprint that my previous board.

boards comparison

That been said the keys feel exactly the same, maybe a bit firmer but it’s that really nice crisp click that I like.

Thinn (but thicc)

Super thin! This was one of the big draws for me, it is thinner than my last keyboard. If you like to have the keyboard elevated there’s two settings to lift the back of the board.

Weighty! It has a considerable weight to it coming in at over 1kg giving it a nice premium feel.


Lights! I would like to say that RGB lighting on a keyboard isn’t important to me but after initially plugging in the G815 and having the initial setting of rainbow cycle set I immediately tried to change to to something solid.

rainbow cycle lights

There wasn’t any presets that were solid so I put the light setting to 0 and then couldn’t make out the keys on the board as it was completely blank.

My touch typing isn’t great so I had to set it to one of the least annoying presets until I figured out how to change them.

Adapting to change

Any key, or key combination used in my usual workflow which involves keys on the left hand side of the board, like Alt Tab, the backtick key, Ctrl all have these G keys next to them.

This is something I’m gong to have to get used to where my fingers usually hover on the left hand side of the board.

Alt+Tab I was instead pressing Super+G2, getting the Ctrl and Super key mixed up due to the additional keys on the side means I have to continuously find the groove between the G keys with my pinky before typing.

Lighting configuration on Ubuntu

Logitech have management software for the G815 with the Logitech G Hub which is available for Windows and macOS users, but as I’m a Linux users that’s no help to me! 🙃

This was nearly a deal breaker for me but I found a Reddit post with someone asking the same question, turns out there is support for it in the shape of libratbag.

I had to add a PPA to install libratbag:

sudo add-apt-repository ppa:libratbag-piper/piper-libratbag-git
sudo apt-get update
sudo apt install ratbagd

Then there was a GUI to use called Piper which I installed from the Ubuntu software manager.

Opening Piper I’m greeted with an image of a mouse holding a 404 sign. So it looked like the software wasn’t working until I tried changing the profiles and saw the lights changing.

I added my preferred colour I wanted for the keys clicked apply and nothing happened, it wasn’t until I switched profiles that I noticed the changes taking effect.


I did find that you can change the lighting in the G in the top left of the keyboard to be a different colour or off all together. I decided to keep it the same as the keys as it looked a bit out of place with the lights turned off.

So far so good

I really like having the media controls above the number pad, yes I like the number pad.

The volume roller is awesome too, has a real nice feel to it with no lag between rolling it and the volume being adjusted on the system.

The keycaps are nice but what I find strange is that the characters on the board are no illuminated like the letters making it a little harder to scan the board visually to find them.

Dem G keys

From reading up on the issue linked on the Reddit post it does seem like I can assign different keys or nothing to the G keys.

For now at least I think I’ll try live with them as is, although the G5 key is mapped to F5 so it may get annoying.

There's a reactions leaderboard you can check out too.
