Description

There is a bug with the Logitech G903 (and probably all devices supporting high-resolution scrolling) where the scroll speed in XWayland clients (and Alacritty) is ridiculously high. This is especially problematic in games where it can be very hard to select weapons for example.

Modification of the scroll_factor variable does not seem to affect the issue.

I suppose this could also be viewed as a regression as Hyprland did not have high-resolution scrolling support for Wayland clients before, thus this bug did not exist. I am unable to bisect right now though.

How to reproduce

1. Connect device capable of high-resolution scrolling.
2. Scroll in an XWayland application.
3. Scroll in a Wayland application.
4. Compare scroll speed.

I also have a Logitech mouse and I have this issue.

Also happening on Logitech M720

Same here. Logitech G502. I confirmed it was an issue with the last several releases of Hyprland as I downgraded Hyprland to 0.40.0 and the issue immediately went away.

[mrmbernardi]

I've got it as well. Particularly annoying in video games

[jordan-josephs]

I have it as well on a G502X. I noticed it in minecraft as I zoom through the inventory bar while only moving my scroll wheel 1 notch.

[acul009]

I'm having that Issue with a Logitech g502 as well.

While I really like it for things like websites, it's basically unusable for gaming. Would it be possible to make this configurable?

I'm happy to provide additional info if needed.

I have the exact opposite of this somehow with my G502 hero. I can unlock the scroll wheel and spin it with a compressed air canister and then only scroll like 1%

Same with the mx master 3. I tried changing scroll_factor and using imwheel, neither of which worked.

I ran a git bisect and this commit d0a224a4915b5a90555818ed3f9e49e1a61b7cdb seems to be the issue

Thank you for the bisect :)

If you read the pull request thread, you'd know that this was known. It was a decision between breaking scrolling after the first click or scrolling too fast. Pick your poison :trollface:. JK, a fix is on the way either in #6608 or soon after because of the new backend making it easier (wlroots does a funny and sway uses a workaround to circumvent this issue)

[mrmbernardi]

Is there a workaround in the meantime?

You can disable the hid_logitech_hidpp kernel module (see this comment on a duplicate issue). After you create the file you need to rebuild your init ramdisk

If you don't want to mess with kernel modules, what worked for my G502 Lightspeed and might work for you as a workaround until this is fixed in hyprland is using it in wired mode instead of using the wireless adapter, as for some reason that doesn't use hi-res scrolling.

I didn't believe you at first but it works :)

This actually broke my system, it made me start in emergency shell

sorry to hear that, i simply shared what worked for me 🤷🏻‍♂️. are you sure you didn't misconfigure your system in another way that caused this?

Maybe but I touched nothing else and it's been 2 hour for now that I'm trying to get as that will boot. I reach the grub, and then ahci error -22 can't find device with UUID However I tried to rebuild the init frames and the problem persist

Edit : I didn't know much about initframe. I'm actually using dracut and thus trying to use mkinitcpio break the boot. It's entirely on me but I think it could be a good idea to specify in your post that people may be using something else and it would break everything Mb again

I wrote up a PR that works on main branch and aquamarine branch. Please have a look at #6881.
