Mouse scroll not working

General
1

hi, i just discovered now that my uhk v2 mouse scroll buttons do not work - the scroll does not happen. this happen only in the mouse layer.

i have tried to listen to the scroll event (on linux, with xev) and when i press the scroll buttons nothing happen. remapping the scrolls to another phisical key does not solve the issue.

any hint? thanks

What firmware version? Does power-cycling the UHK resolve it?

You said it only happens on the mouse layer; do you mean that if you map it to a different layer, it will work? But remapping it to a different key on the Mouse layer won’t? If so, that would be rather strange, but just trying to clarify.

What firmware version?

Right keyboard half firmware: UltimateHackingKeyboard/firmware: 15.0.1
Left keyboard half firmware: UltimateHackingKeyboard/firmware: 15.0.1

flashed with UHK.Agent-8.0.0-linux-x86_64

Does power-cycling the UHK resolve it?

yes, it did solve the issue, will come back here if it happens again

You said it only happens on the mouse layer; do you mean that if you map it to a different layer, it will work?

this i haven’t tried

But remapping it to a different key on the Mouse layer won’t?

correct, remapping it to a different phisical key on the mouse layer does not work. mapping another function (move up) to the same phisical key worked for the move up for instance. so the problem was the ‘scroll’ only.

as said, power cycle fixed it, will come back if it happens again (for instance, i keep the computer on 24/7, i am on linux).

thank you

OK, I know there have been some issues with scrolling on Linux recently, but I’m unsure if your particular issue has been addressed or not. Hopefully the devs will have more insight.

In the meantime, could you try using the reboot macro to see if that also resolves it? Hopefully that works as well, so you don’t have to fiddle with the cable when it happens.

What triggered the state? E.g., did it happen after wake from suspend?

Is there a hub between uhk and your pc?

What was the uptime of that UHK? (Time since it was last power cycled.)

(Working hypothesis: it has to do with high res scrolling.)

Btw., newest firmware is 15.2.0 Releases · UltimateHackingKeyboard/firmware · GitHub

it happened again.

  • reboot macro: i don’t have it
  • after wake up from suspend, not the first one though (i systemctl suspend every night)
  • uptime might be days, excluding the suspends

i will now try getting the firmware 15.2.0, will report back in case

You can create a new macro in Agent’s left panel, and then type reboot into the macro command entry field:

Then map it to a free key:

reboot macro restores the behavior.
the mouse scroll not working bug does happen after the pc is waken up from suspend (systemctl suspend)

Right, this a high res scrolling linux kernel bug. See Fix broken scrolling on Linux wake from suspend by rightaditya · Pull Request #1355 · UltimateHackingKeyboard/firmware · GitHub for more details.
