Potreboval jsem zpomalit ukazetel mysi, ale o extremni hodnoty. Graficke klikatko v Ubuntu, ani v Mintu mi nedovolilo nastavit tak velke hodnoty zpomaleni, proto jsem byl nucen pouzit xinput utilitu.
Graficke klikatko pro nastaveni mysi v Mintu 16
Nejdriv je potreba zjistit dostupna vstupni zarizeni:
martin@martin:~$ xinput --list --short

⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=13 [slave pointer (2)]

Pro zacatek si o mysi zjistime blizsi informace:

A nyni sestavime zpomalovaci prikaz (nastavime patricnou hodnotu):
vychozi hodnota je 1, cim vyssi cislo, tim pomaleji se bude mys hybat.

a je to!
Po opetovenem prihlaseni bude nastaveni ztraceno. Jestli se ma zachovat, musime ho nekam ulozit. Primo se nabizi pouzit soubor ~/.xsession . Vlozime do neho:
#!/bin/sh xinput --set-prop "2.4G Wireless Optical Mouse" "Device Accel Constant Deceleration" 5
a nastavime mu pravo spusteni (chmod +x ~/.xsession). Nyni by se nastaveni melo aplikovat automaticky po prihlaseni uzivatele.
