Input lag on Manjaro version 0.1.21 for TKL Pro

[n1coh]

Hello, I have lag in input on a TKL Pro, I am on Manjaro. I have upgrade to version 0.1.21, I thought that the correction of the ticket #76 would correct the problem but not. When executing these commands everything goes well (no lag) :

 $ sudo RUST_LOG=debug eruption
 $ sudo RUST_LOG=trace eruption

journalctl :

août 18 11:37:52 nicolas-pc eruption[741299]:  WARN  eruption                                   > More than 82 milliseconds of jitter detected!

Hi @n1coh, thank you for reporting this issue!

Are you using the AUR package eruption or are you using the package eruption-git of which the current version would be 0.1.22.r0.gf0cb968-1.

If you are using eruption then please try out the eruption-git package first!

If switching to eruption-git does not fix the problem, then please post the full output of:

 $ sudo RUST_LOG=debug eruption

And the full output of this would be nice to have too:

 $ sudo RUST_LOG=trace eruption

Indeed, I had not seen this update on eruption-git ... my bad I have no more lag with this version. Thx for your work. I have a ROCCAT Kone Pure first of the name btw, I can help to add it to the devices list if you want.

[X3n0m0rph59]

@n1coh Great that it works now! I will soon do a release of the non -git package too.

I believe the ROCCAT Kone Pure is not an AIMO device, but I am not completely sure about that. If it is not that would mean that the embedded controller is too slow to handle realtime color updates. It then could just be programmed to a color in a one shot mode.

Is the device compatible with ROCCAT Swarm or does it require another driver Software?

[n1coh]

You are right, it seems to me that another application is needed

@n1coh you can use the "legacy" roccat-tools package for that, which I think are unfortunately not maintained anymore since there are also no new devices made that would be compatible.
