Libinput changes sensivity/accel randomly
i open this post to ask about a problem that i have with my Thinkpad T480s and his touchpad working with every linux distro for desktop environment that I ever tried.
The thing it's a little bit difficult to explain, but the feeling of the touchpad it's a little bit weird sometimes. I tell sometimes because the mouse acceleration or sensivity it's not always the same as I feel. Sometimes it is very linear like W10, that is what i want but randomly it changes to a strange weird feeling of acceleration or sensivity that feels the coursor/touchpad very laggy or strange. When it turns bad, the small movements are terrible and impossible.
I cant understand what's happening here, I'm using libinput driver which is supossed the "standard" after synaptics driver. I tried with Arch(Antergos), Ubuntu, Fedora and all distros are the same, doesn't matters the DE Gnome or KDE or XFCE. I don't know if I'm missing some parameters to config in the driver but i can't understand this, if you could help me I would be very grateful. The rest of the touchpad works very well, I mean the clickpad buttons, the buttons on the top of the touchpad, right click, button simulator....
If it helps, I'm using this laptop. Lenovo T480s Intel i7-8550u 2560x1440p display 8GB RAM
