Conflict to Logitech G304 mouse

Closed this issue · 13 comments

Hi there,

I am using Logitech G304 wireless mouse as my mouse and a common wired keyboard

/dev/input/by-id$ ls
usb-0c45_USB_Keyboard-event-if01
usb-0c45_USB_Keyboard-event-kbd
usb-0c45_USB_Keyboard-if01-event-kbd
usb-Logitech_USB_Receiver-if02-event-mouse
usb-Logitech_USB_Receiver-if02-mouse

When I boot to the system, as the dvorak runs, my mouse can't move the cursor anymore.
All the buttons failed to function as normal, except the right click. The right click can only fire once, and then it doesn't trigger anymore.

After systemctl stop 'dvorak@*.service', my mouse worked as normal again.
It seems that the program considers device with Logitech is a keyboard.

I can't find the setting to ignore my mouse on either 80-dvorak.rules or dvorak@.service.
Is there any method I can still use my Logitech mouse?
Or do I need to provide more logs for you to locate this issue?

Thanks.

Interesting, I added a "auto-detect" feature, and I enable the service based on which keys are present:

//check if X, C, or V are present, if no, then its not a keyboard, exit
    if (!(array_bit[KEY_X / 32] & (1 << (KEY_X % 32))) ||
        !(array_bit[KEY_C / 32] & (1 << (KEY_C % 32))) ||
        !(array_bit[KEY_V / 32] & (1 << (KEY_V % 32)))) {
            fprintf(stdout, "Not a keyboard: [%s].\n", device);
            return EXIT_SUCCESS;
    }

Can you check your journal if you see if your mouse is detected as keyboard?

As a workaround, you can use the -m option in the dvorak@.service file:

ExecStart=/usr/local/bin/dvorak -d /dev/input/%i -m keyboard

And this will match your entries (lowercase), where the name contains the character keyboard.

To test the parameters you can call dvorak direcly (without using the serivce).

/usr/local/bin/dvorak -d /dev/input/by-id/usb-0c45_USB_Keyboard-event-kbd -m keyboard

Thanks for the quick response.

I wonder

  1. In what path can I find the journal? I'm not quite familiar with debug service.
  2. As it showed, my keyboard is detected as usb-0c45_USB_Keyboard-event-if01, should I use -m keyboard as the example, or -m Keyboard with capital K?
tbocek commented
  1. If run from the service, then I typically run journalctl -f, and the logs appear, if you run directly, it will be shown in the console.
  2. The match is case insensitive, so keyboard, Keyboard should not matter

Hello again,

I've tested it on 3 different mouses.
It affects all wireless mouses, and slightly affects my wired keyboard too.
Here are the journals: (mcv is the PC name, you may ignore it)

Also, I found I can't fire ctrl+c with keyboard in journalctl. It just printed 4 spaces (just like Tab) in terminal.
After systemctl stop 'dvorak@*.service', my keyboard can stop journalctl with ctrl+c normally.

I tested these on newly installed Linux Mint 22.
Hope the info can help you to locate the issue.

tbocek commented

I just added more output to see what keyboard is detect. If you checkout the latest master, you should see a string: "Staring event loop with keyboard:". Can you tell me how this line looks in your log?

tbocek commented

I just found a mouse, where I can reproduce it: M720. Investigating...

lotc commented

I used this program on Ubuntu about two years ago (can't remember the exact date). It didn't conflict with any hardware.
I have recently changed to Linux Mint on my new PC.

The systemctl mask systemd-udev-settle.service in the README makes no video output after boot. I'll be busy with that now.
Since it's not caused by your program, you don't have to solve that here.

Before further testing, I'll wait for your report on the M720 mouse.

tbocek commented

quick update: the mouse advertises that it has all keyboard buttons. I guess this is due to being a gaming mouse, where mouse buttons can be configured as keyboard events, which makes sense.

When implementing this library, I was wondering if I ever need to implement REL or MSC, as stated here in this line:

dvorak/dvorak.c

Line 348 in d1d1f68

//use REL, MSC? https://gist.github.com/CyberShadow/ae30a8d9f86c170c2451c3dd7edb649c
. Now I know, why its important to implement.

lotc commented

I have no clue if you are right.
Please check the photo below first:

photo_241121
From the top to bottom are:
Off-brand wired mouse, with two side buttons act as back and forward in web browser and file explorer.
Logitech G304 mouse, with two side buttons act as back and forward like the upper one.
Rapoo M10 mouse, with no side buttons but only left, right, middle click and scroll wheel.

If it's blamed on the keyboard events, it should be caused by side buttons.
But the off-brand one got side buttons can still perform normally.

If you want me to take further tests on one or any mouses, please let me know. I can scrape the logs for you.

tbocek commented

I now changed that ABS/REL is also mapped, as well as the ABS setup (but I have not tested it with any absolute device / tablet). My mouse now works as it advertises that it has all the keyboard buttons, and now the positions are properly propagated.

I also cleaned up lots of stuff. I have not tested extensively, but will do so, as this is my daily driver.

Just swap back to the old Windows PC.
Will do the tests and post the journals ASAP with new code.

Greeting,

The new code works fine.
Here are the journals if you need them for further analysis.

As for the problem that systemctl mask systemd-udev-settle.service breaks the video output, it seems caused by the USB-C connection.
I was trying to boot Linux on an external ssd drive via usb-c cable. I might dig it later.

I will close this issue since it's fixed now.
