Create and name your lighting effect in Freestyle mode.Go to keyboard settings (a cog icon in the upper left corner)In the lower right corner of the settings add your named effect to the keyboard memory, but DO NOT switch to the onboard mode yet.Exit the settings and go back to lighting editor.In the editor, change effect type to preset instead of freestyle. Open the drop-down with presets and you'll see your own custom lighting at the bottom of the list. Select it. Only presets from this list can be stored as default in onboard mode.Now go back to settings, turn on the onboard mode and select your default profile, for which you've set your custom effect.

You can use default settings available from keyboard, by using * with any number from 0 - 9. It is working only temporary. After waking up keyboard from saving battery mode your chosen lighting will reset to default one.
G Hub software - not useful too much on Linux, but I saw that people try different solutions using G Hub software on Windows and switching back to Linux. More info is on GitHub thread in g810-led project
You can use Ratbagctl project - It's solution that I use on my Logitech G915 TKL keyboard and it is working good for me. But you need to be careful. It writes configuration to onboard flash (it overwrites the stored profile on your keyboard). Some people after using it had problems with power saving settings. I did not.
You can use G810-led PR for G915 - It is the most flexible solution available right now, but I had the same problem like with default settings. After waking up keyboard from saving battery mode my setups were gone. There is a workaround for that, but I didn't try it. Ratbagctl was enough for me.
If you are platform locked with Windows-only software from Logitech, you might also want to check with their documentation to see if it has on-board memory allowing you to keep your settings even when connected to a different PC or a different OS.
With G Hub, you can load your custom lighting and inactivity setup as the default profile (replacing the rainbow) with the onboard mode . Then you can use it with Ubuntu or any other computer and it will stay as the keyboard's default profile. I just wrote a tutorial about it : @alexis.j.boix/logitech-g915-onboard-custom-lightning-f9afb550c678
There is no doubt that TenKeyLess keyboards are popular among gamers because they provide more room for mouse movement but finding the right one in a market saturated with poor quality gaming keyboards is hard. Recently Logitech released the G915 TKL keyboard which is a wireless mechanical keyboard that uses low-profile switches to providethe speed, accuracy, and performance of traditional switches but at half the height.
Logitech is selling the G915 TKL in white and black color but the white color only comes with the GL Tactile switch while the black color is available in three switches; GL Clicky, GL Tactile and GL Linear.The GL switches are essentially the Kailh choc switches that are found in other gaming keyboards. My review unit came with the GL Clicky switch which I find a joy to use.Now let's talk a little bit about the different GL switches.
The GL Tacticle switch provides a discernible tactile bump during actuation and it is not too loud or distracting.It is ideal for gamers who are into fast-paced gaming due to the short travel distance which plays a huge role in improving the rate of repeating keystrokes.
There is also the GL Linear switch which provides a fluid and smooth keystroke and is great for double-taps, rapid keystrokes and uninterrupted half-presses.Similar to the GL Tacticle, the GL Linear switch is also good for gaming. The GL Linear is built upon without tactile point which further enhances the actuation speed.
From a build quality perspective, the G915 TKL features a modern slim design with an aluminum alloy top case and a steel-reinforced base which looks really good. It weighs 810 g (28.6 oz) without including the cable and measures 368 mm (15.2") in length, 150 mm (5.9") in width and 22 mm (0.9") in height. I love that it comes with a 6 ft long cable that it is nicely braided. Braided cables offer extra durability and are very much preferred by gamers.
The G915 TKL utilizes the LightSync technology which lets you customize full spectrum color lighting per key.You can customize every color to match your setup across keyboards, speakers, headsets, and mice and you can even create your own animation effects. Logitech has placed the LEDs in the center to minimizes light leakage and to focus the light evenly through the top of the keys for a cleaner look.
Looks-wise, the G915 TKL sports a borderless design which means the keys will stick out over the platform.Some users might not like this because the key caps basically hover above the platform without any protection on the sides and dust can easily accumulate inside but at the same time this makes the keyboard much easier to clean and maintain.
A feature that the G Pro lacked when it was released was the lack of dedicated media controls but the G915 TKL fixes that by including a variety of dedicated media controls. With the G915 TKL you can easily change the lighting effects and adjust brightness with onboard controls. You can select from seven preset animations by pressing the brightness soft key plus numbers 1-7 and you can also create up to two of your own lighting profiles using G HUB software and save the profiles to numbers 8 and 9.
Something else that the G915 TKL lacks is a USB passthrough. A dedicated USB passthrough can be useful if you you want to charge your smartphone while playing a game or when browsing the web but I guess it is not a deal breaker.
Many high-end premium keyboards use PBT keycaps which are more durable and don't suffer from legend wear butthe G915 TKL comes your standard ABS keycaps which you would not expect from a keyboard that sells for $230. I really wish Logitech had gone with the higher end PBT keycaps.
As I've already mentioned, my review unit came with the GL Clicky switches. I tested the performance of the G915 TKL by playing World War Z, Battlefield V and Hitman 2 for a few hours each. In my experience, the G915 TKL offers an excellent gaming performance thanks to the low profile switch which needs less travel distance before they actuate.For games that require quick response time such as Battlefield V, the G915 TKL delivers a great experience and I did not notice any lag while playing in wireless mode.The keyboard itself is very comfortable to use and its sturdy design can withstand forceful tapping with no problems which is very nice.
Logitech's G Hub Software has a simplistic look and feel which I really like. You can use the G Hub Software to manage all Logitech accessories, such as mice, keyboards, and headsets. It allows you to customize things such as lighting effects, media controls, per app profiling, create macros and much more.Third-party apps like Discord and OBS are integrated into the G Hub software which is great if you want to download and share custom game profiles with the Logitech G community.My favorite feature of the G Hub software is that I can set up per-game profiles to automatically adjust certain aspects of the keyboard when I launch an application. I can assign any custom function to the F1-12 keys and also create macros and scripting features. You can basically create an unlimited amount of customization with Custom Function Keys and can even save and export the profiles you create to share with other people.
In the LightSync window, you can customizing different lighting effects and animations.After you pick the lighting effect, you can then experiment with the color selection, brightness, speed, and direction. There are plenty of different lighting effects options to choose from such as static, breathing, wave, rippling, etc.
The ABS keycaps are the most common keycaps used in keyboards and that is because they are inexpensive and they are also prone to fading and losing their texture. PBT keycaps on the other hand have better texture and feeling than ABS but also cost more. If Logitech decides to make another revision to the G915 TKL in the future, they should definitely consider using PBT keycaps.
I have been using the G915 TKL for the past week mainly for gaming and I love its sleek and slim design.Logitech has created a top-notch gaming keyboard with the G915 TKL and its low profile GL switches delivers a great gaming experience.I would strongly recommend the GL Clicky switches for someone who is looking for a keyboard that is both for typing and gaming.
I will say that the G915 TKL has become my daily driver because of its sturdy build quality and wireless performance. I am also a fan of Logitech's G Hub software because it offers a ton customization options such as the LightSync technology which allows to customize individual keys to have its own RGB lighting.
Pros:
+ Good Battery Life
+ Low Profile Design
+ Fantastic Wireless Performance
+ Dedicated Media Controls
+ Great Typing Experience
+ Sturdy Build Quality
Cons:
- ABS keycaps
- No Wrist Rest
- Expensive
If you are in the market for a high-end mechanical gaming keyboard, the G915 TKL is definitely the keyboard to get. It offers everything you could want in a TKL gaming keyboard and then some. Overall, I believe the Logitech G915 TKL keyboard deserves our Editor's Choice award.
I have a Logitech K800 wireless keyboard and Performance MX mouse running off of the same Unifying Receiver on Windows 10. All of a sudden, the keyboard doesn't type anything. The function keys work (I can mute, change volume, etc), but I can't input any numbers or letters.
I tried using the keyboard on another computer and it works just fine, so it must be a Windows issue. Strangely enough, my spare Mac corded keyboard works just fine (and that's what I'm using to type this)...
Searching for this issue and trying the few suggestions doesn't yield any success. Many recommend updating the device driver from the Device Manager, but the only keyboard listed is the corded Mac keyboard. Plugging the Unifying Receiver into different USB ports also doesn't change anything, nor does simply rebooting the machine.
