hello, since I'm using solus my pointer gives small constant jumps with intervals of 1.5 seconds or so, I'm currently in i3 but this also happens in budgie and gnome x11 / wayland and to make it rarer also happen in GDM / lightdm. I'm pretty sure it's not a physical problem, if I disconnect the mouse it keeps happening, if I connect a different mouse it keeps happening, whether it's wireless or wired doesn't change anything.

The only thing that occurs to me is that the touch-pad generates some incompatibility, ¿any idea what it is and how to fix it?

    Facundo-c-c if I disconnect the mouse it keeps happening

    Is that only the 'external' mouse? Have you tried disabling the touchpad?
    Sometimes there is a keyboard control to disable the scratchpad or alternatively disable it in the settings program.
    Failing that maybe try the live environment of a non-Solus distro which should provide a good indication of whether the fault is disto related or hardware.

        BuzzPCSOS yes you was right, it should be something weird about touch pad, i read something and
        xinput --list
        xinput --disable "ID"

        It wasn`t fixed but it stop, now I have to disable the touchpad manually at each start because the id assigned to each "device" changes but at least the mouse dont move

          Not sure about i3 and Gnome but in Budgie Control Centre under Mouse & Touchpad there is a simple toggle to disable the scratchpad. Most likely something similar for the other flavours.
          Might make for a permanent solution to your problem.
          Alternatively you might choose to pop out the keyboard (search for a relevant 'how-to' video) and there should be a zif connector for the scratchpad that will allow you to drop the connection with minimum effort.
          Good luck.

          For my laptops I always disable the trackpad in the BIOS, once and for all, as it gets in the way of typing. I use usb mouse instead.
