Stopped to work after an upgrade

[stepanselyuk]

Hello,
this utility stopped working a few months after some upgrade (not sure what I did, first I updated kernel to 5.14.14, and then the system (Ubuntu 21.10) asked about some partial upgrade. After then GNOME40's three fingers gesture somehow returned and I had to use Gnome Shell Hammer extension, but even if it helped with moving 3 to 4 fingers issue, the libinput-three-finger-drag still was not working. I downloaded code, added some verbosity and then I had an issue with compiling because of an issue with libxdo. So I reinstalled packages:

$ sudo apt reinstall xdotool libxdo3 libxdo-dev

after that compilation succeeded and 3-fingers drag (including selection, because this is a general hack with the mouse) worked!

Just writing this here because someone probably will have such an issue and will check this repository.

Three Finger Window Move extension works great, but it's not hacking with a mouse and it really just drag windows from any point inside of it (and prefs.js should be updated to work with GNOME40).

Actually it stopped working after restarting, and I still cannot find a way how to fix it.

                    let x: f32 = parts[6].parse().unwrap();
                    let y: f32 = parts[7].parse().unwrap();
                    xsum += x;
                    ysum += y;
                    println! ("{:?}, {:?}", xsum, ysum);
                    if xsum.abs() > 2.0 || ysum.abs() > 2.0 {
                        xdo.move_mouse_relative(xsum as i32, ysum as i32).unwrap();
                        xsum = 0.0;
                        ysum = 0.0;
                    }
                }
                _ => {
                    xdo.move_mouse_relative(xsum as i32, ysum as i32).unwrap();
                    xdo.mouse_up(1).unwrap();
                }
            }

It's working (text selection) inside of IDE and some windows (but not Terminal). But dragging windows not working at all. Weird thing... like some events or software mixed with each other.

run
libinput debug-events
in a terminal and check what events will happen when you select in Terminal or drag a window?

I see normal events,

GESTURE_SWIPE_BEGIN ...
GESTURE_SWIPE_UPDATE ...
...
GESTURE_SWIPE_END ...

[marsqing]

If the events are correct, maybe there's some problem with libxdo.

Yes, something changed in the kernel. I tried to use 5.14.0 as before and all is working. But with 5.14.14 it is not.

Was this issue solved ?

On 5.16 it's working fine :-)

Thanks a lot @stepanselyuk
Btw, I see you are the creator. If I install the 3finger drag, will the "linux" 3 fingers paste still work ?
