Ahoj,
resim problem s trackpointem na X1 Carbon Gen6. Chodi nepouzitelne rychle, jen se ho dotknu a je nekde pryc :-/
Na stare X220 chodil prijemne pomalu.
Mam Mint 19.2 a jadro 5.1.21.
Zkousel jsem to pres xinput (xinput --set-prop 12 'libinput Accel Speed' -1.0) ale nemam pocit, ze by to nejak vyrazne pomohlo.
Jde to jeste nejak jinak?
