Greetings
It's been well over a decade since i did anything serious in Assembly and almost a decade since I last used Modbin so I don't know for certain that such things are even possible these days but I need to try.

The Problem - I just bought a Logitech G910 mechanical gaming keyboard and it's really great except for one thing that I abhor. All the keys are lighted which is fine but the default setup is a wave-like cycling of color sort of like a flowing rainbow and I hate it. It maybe attractive on some salesroom floor (mine wasn't plugged in so I had no idea) but for any manner of serious work itt's just ludicrous and annoying beyond belief.

This "feature" can be changed in Windows, and I assume in the Mac version as well, with the LGS downloadable software from Logitech but it instantly reverts to this horrid Rainbow Wave default as soon as LGS is stopped or never started and I want it OFF and PERMANENTLY. I care less about what color it defaults to than just that it never ever cycle this stupid wave of changing colors ever again under any circumstances.

Surely there is a way to alter the default, yes?. Back in the day o ISA video cards the ATi All-in-Wonder card had an app that accessed it's CMOS settings and I could pretty much duplicate (and go beneath that) with DEBUG. Is there some means these days to do a similar operation? FWIW I don't care at all about voiding any warranty. I'd snip an IC leg to the oscillator if I knew which one it was. Yeah..., it's THAT annoying.

Any help or suggestions gratefully desired. Thanks in advance.

I have a G413 Carbon - the function+F7 turns the lights off. I have to do it every time though. Mine does not "cycle", it just has various brightness settings.

I still have my Logitech G15 keyboard. It has a way to disable the orange lighting by pressing a special key. I was under the impression that all Logitech keyboards had a way to do so. Maybe there is some key combination you can use?

Just to be clear I don't want to disable key lighting and there is a key that is an On/Off key for that. I want to stop the oscillation that causes a constant wave of color change sweeping over the keyboard. It is apparently a "Default Feature" since it occurs immediately upon powering up before any OpSys is loaded.

Examples: If I enter CMOS Setup the Rainbow Wave is in full force. If I am in FreeDOS or Linux it is doing the wave. If I don't load LGS in Windows it is doing the wave.

I need to reset the Default to one color that doesn't wave or waiver. I expect that is in the firmware and should be a simple software switch. Possibly there is a second switch as for what color it defaults to but that is less important than the wave cycling.

actually I have a logitech gaming mouse and I need to boot windows and start logitech config to set up that device. I can use it in linux (using my setup), but unable to config.
Probably there is a better solution for you, but I think linux is not officially supported.

Hello pan64 and thanks for your response. It doesn't help me at all but maybe I can help you. Mice, even high performance gaming mice, are easy to setup in Linux as long as you know what your mouse will support.

Hi, thanks, but unfortunately not, this is not what I meant. My control panel (which works only on windows) can control the lights of the mouse (among a lot of other things - like automatic and game specific configuration). So probably it is possible, but need to know how to communicate with that device. And there is no such driver available for linux (as far as I know).

Sorry, i meant to say, I know how to buy a moddable keyboard; c'est la vie...

Hey there Jamison
I am a long time veteran of researching my hardware purchases so that I know ahead of time they will be compatible in every OpSys I care to run.... excepting mice and keyboards since the feel has to be checked out in person. I live way out in the mountains and there are only two stores within 50 miles that carry keyboards and mice of any serious performance quality. Only one of them has any selection to speak of at all. I don't care about the programmable extra keys which I'm reasonably sure I can make function anyway.

The only thing I want to accomplish and which I had no way of knowing going in is this cycling wave of color sweeping across the board. I just want those changes to cease by default. I'd be shocked if that is impossible but so far I've yet to hear back from Logitech.

On my older IBM thinkpads there's a driver set for Linux to get the functionality of keyboard* to work. I know most of those newer color-changing ones have a function key to turn them on and off, at least my Dell gaming laptop does.

A quick search for your problem (:logitech linux keyboard lighting effects) I see they're up to the g810 series at GetHub*?

!!! W O W !!! I had no idea it had gotten that far. Thank you Jamison!

Some sarcasm tags would be nice... hehehe but still you know the game? Free.

Most here don't know how to search, the bulk of my rep comes from searching for people but that gets old. Quite frankly have you searched how to program or pay a programmer, perhaps out of spite for me one will step up here otherwise wait*...

ping Jamison - Then I suppose you're familiar with searching for things like "Index of <term>" (very often, apparently, "term" = some variation of "pr0n" ;P but is in no way limited to such a common term)

Searching is a huge implementation of AI and works amazingly well, assuming something actually exists. Deep work that I did back in the 80s and 90s (hot-swapping bios chips, cross installing firmware, etc) doesn't seem to be very popular 30 years later so searching via search engines alone isn't enough. If I don't get a viable answer in a week or so I suppose I will brave the sticks, stones, trolls and flames of Reddit. I haven't visited Slashdot in ages so I might check in there as well. I will refrain from the Badlands that is 4Chan, tho.
