Koska nykyisellään touchpadin toiminta kirjoittessa on todella hankalaa johtuen kursorinpomppimisesta sinne sun tänne. Kävin Ubuntu Forumilla osoiteessa:
https://www.reddit.com/r/Ubuntu/comments/5z99ob/new_touchpad_sucks/#bottom-commentsSieltä sain toistaiseksi parhaan neuvon, joka mielestäni muistutti nm:n aikaisemmin Ubuntu 17:04 tai10:n aikana antamaa. Kysyisin kannattaako alla olevaa neuvoa käyttää, vain onko vaarana, että sotken koko koneen?
You're definitely not alone in this, my touchpad used to be "jittery" as well. I "solved" this by using libinput. Now, Ubuntu is using synaptics + evdev for handling stuff like touchpad input by default. However, other distros like Arch already use libinput for handling these devices, which is supposed to be newer and maintained.
How I installed it:
sudo apt remove xserver-xorg-input-synaptics xserver-xorg-input-evdev
sudo apt install xserver-xorg-input-libinput
Then reboot. Try and see if you like it, if not just revert these two steps.
One note though: libinput does not yet allow edge scrolling and two-finger-scrolling at the same time, you have to choose one. Also, tap-to-click is disabled by default. To enable it, create the file /etc/X11/xorg.conf.d/30-touchpad.conf and put the following in it:
Section "InputClass"
Identifier "touchpad"
Driver "libinput"
MatchIsTouchpad "on"
Option "Tapping" "on"
EndSection
I hope this helps. Maybe in the future libinput will be supported by Ubuntu's GUI as well.
