Mouse cursor doesn't move on the Y axis

[anthrazitrr]

After i installed maccel and rebooted, the mouse cursor stops moving on the Y axis.
The issue persists on both stock and zen kernel.

OS: Arch Linux 6.8.1-zen1-1-zen
Server: Xorg with libinput

Wow that is wild. I have same setup on my daily driver - same os and server you listed. So, I don't think it's that.
But I'll test it out in a VM.

I guess I should have some kind optional tracing setup for situations like this. I can't infer enough from the video.

@anthrazitrr Which mouse are you using? Can you try another one.

[anthrazitrr]

I'm using Glorious Model O Minus if you're wondering, but i will try a different one.

Could it also be that OpenTabletDriver is the issue?

UPD: Tried on a different mouse, even uninstalled opentabletdriver, and now the cursor doesn't move at all.

[Gnarus-G]

Wild. What was your suspicion about opentabletdriver?

So, I'll have to set up a debug build for this. If you are willing, you can use it to troubleshoot.

When i was using leetmouse it was breaking the tablet driver.

After i installed maccel and rebooted

Btw, rereading your first comment, does that mean it was fine before you rebooted? - or you didn't use your mouse until you rebooted.

As for debugging, so far here's what we can do:

Can you clone this repro, and checkout the debug-build branch: git checkout feat/debug-build
Then, at the root of the repo, you

• sudo make uninstall if you had it installed, probably not
• sudo make debug_install
• sudo dmesg -w and move your mouse around,
  • taking note of the line move input log lines, like "[MOUSE_MOVE] input (x, y)"

What I expect is that as you move your mouse

• left, x is negative
• right, x is positive
• up, y is negative
• down, y is positive

0 means no movement. The faster you move it the bigger the absolute value of x/y.

What do you notice when you try it? I would appreciate a video like last time. Let me know if I need to clarify these steps further.

Sorry for not replying for 5 days, here's the video.
Every time i move my mouse to the left, kernel log reports y as -1, which is very strange.

[Gnarus-G]

Sorry for not replying for 5 days, here's the video.

Absolutely no worries at all.

Thanks for the video. I have a suspicion that I'll look into.

[anthrazitrr]

Also, could the problem be caused by Glorious mice relying on a separate driver in the kernel?

[Gnarus-G]

Yeah, after reading that now I think the normal hid driver in linux does something for this mouse that I am not doing. Btw my suspicion from before didn't really pan out.

I am gonna buy that mouse and use it for debugging. If you could hook me up with an direct link, like an amazon link or something, that'd be cool.

I think I can spend some time on it this weekend.

[anthrazitrr]

I've bought it in a local store in Ukraine, so unfortunately I can't help you with that.
I might just buy a new mouse and call it a day. But the problem still needs to be resolved. I have high hopes for this project.

[anthrazitrr]

I have tested every mouse I have:

Don't work at all with maccel:
Logitech M650 Wireless
Bloody T7 Winner

Misbehaving input:
Glorious Model O/O-
Hator Stellar Pro Wireless (reports as Telink Stellar PRO Mouse)

[Gnarus-G]

Yean I am sorry to hear that.
Now that I have played around with the Glorious Model 0- I bought, I found out that the problem is that some mice report the movement values in very different formats.

Leetmouse was kind of handling it with a custom parser for different types;
So it will be an adventure for me to port over linux's handling of all different mice.

For the record: I have tested (am using):
Razer Viper
Razer Deathadder V2

Hey, i really got excited when someone posted your project on discord, because mouse accel is essential for me, but when i activate it my vertical movement gets locked and it becomes scrolling wheel instead lol, i am using Lamzu Thorn 4k.

[Gnarus-G]

Alright guys, @anthrazitrr, @ParanoIIa91

I have ported over leetmouse's parser over in another branch.
If you can, try it and let me know if it helped you.

Basically:

• clone this repro: git clone https://github.com/Gnarus-G/maccel.git
• checkout another branch: git checkout feat/leetmouse-hid-parser
• sudo make uninstall: if you had it installed, probably not
• sudo make install
• sudo maccel bindall: in case it maybe didn't bind automatically.

P.S. I don't have a lot of faith in this approach as even leetmouse's author warned against this custom parser strategy. Still, this was the fastest of all the approaches I brainstormed. The right fix is going to take me a while.

[ParanoIIa91]

I am not very good with Linux yet, but this is what i am getting?

[Gnarus-G]

@ParanoIIa91 No that's my mistake: wrong command.

Use git clone https://github.com/Gnarus-G/maccel.git

[ParanoIIa91]

mouse cursor still behaves weirdly but i dont think those commands did anything, maybe i am doing something wrong?

@ParanoIIa91
Delete the maccel folder that you already have:
rm -rf maccel

Then clone the repo again:
git clone https://github.com/Gnarus-G/maccel.git

Change the current directory to the newly cloned maccel folder:
cd maccel

Checkout the branch that has the experimental HID parser:
git checkout feat/leetmouse-hid-parser

Uninstall the previous version:
sudo make uninstall

Install the new version:
sudo make install

Pro tip: if something doesn't work, look at the output of the command.

The new HID parser works for me, I have tested Hator Stellar Pro Wireless and Glorious Model O- so far.

[ParanoIIa91]

Thank you very much, its actually working! First time in my linux experience, i found a proper mouse accel project, that actually works, now i just need to mess with settings, because i am not sure yet, how exactly doest it work :)

[Gnarus-G]

I am glad to hear it's working for you both. I will keep this issue open for now and direct other people to it when applicable. Depending on how long it takes to research a better fix, I might merge that branch and put this parser behind a flag.

[Gnarus-G]

@ParanoIIa91
