Issue with scrolls events just happening repeatedly

Support
1

So I’m not sure what exactly happened but all of the sudden I just started getting weird horizontal scroll behavior. When I’m in a browser it will just automatically scroll to the last tab in the list. I’m at a loss as to what I did to cause this and any help would be appreciated.

So with some digging I ran sudo evtest and got the below output.

The REL_HWHEEL event just keeps firing over and over again.

Any way to discount hardware?
Maybe checking another system or live ISO?

scroll back is not an option?

+1. I’ve seen (loosely) related issues with mice, etc. .

Sounds like it could be a hardware fault, maybe dust or other contamination? Badly worn wheel indexer? I had to “disable” the scroll-wheel indexer in my ancient MS mouse (percussive maintenance), as it started randomly jumping all over the place, and if the pointer was on the tab bar, it would do similar to what you describe.

So its happening on the laptop directly, no external mouse or keyboard connected. Also I dual booted into Windows and confirmed that it doesn’t happen in there.

I’m wondering if I hit some weird key combination and activated something that is causing but I don’t know what it is.

Was having trouble getting my screencasting working so just took a video on my phone:

I can also add that by disabling xinput id=12 the issue goes away

Does your Laptop have a touchpad ?

Events from the edge of the touchpad are often used for scrolling.

That sounds a lot like a speck of dust stuck on the edge. Or the touchpad generates events for other reasons when the laptop is moved or touched.

My recommendation:

  • Clean the touchpad
  • Deactivate the touchpad for a test

Tried both shutting of the touchpad & disabling horizontal scrolling and neither of those helped

I forgot I had a USB receiver and that the Mosart 2.4G was that receiver. I don’t normally use the wireless mouse as I’m working from a docking station with wired accessories. I first tried removing the battery from the mouse but it didn’t change anything. Proceeded to remove the receiver and it went away. Didn’t appear to come back when I plugged it back in. I’ll keep an eye on it when I’m rebooting and such.

Thanks for the suggestions but I think this is case closed
