Got here through bug #1576685 and #1351772 (duplicates or very related): Summary of my experience with disable while typing feature:
(1) The synaptics and libinput package worked well for me in 16.04 (and previous version to 12.04 I think) up to 17.04 on thinkpads (x2XX to carbon X1). Currently I'm using carbon x1 5th gen. There is however some form of instability with settings that affects many users including me. Sometimes the disable while typing feature stops working and reinstall of libinput and synaptics drivers help. I.e, reinstall xserver-xorg- input-synaptics and -libinput as well as running: gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true https://help.ubuntu.com/community/SynapticsTouchpad#Touchpad_not_working_after_login However, what perplexes me is that the gnome desktop (gnome default) does not work with synaptics disable while typing when it clearly works in unity at the same time. I'm testing gnome before 18.04 and login/reboot in/out between both desktops, with the exact same settings (gconf, drivers etc). Currently I'm writing this in gnome and the cursor skips with random artefacts that make the keyboard defunct. In unity it works perfectly (two finger scroll, trackpoint etc works in both desktops). (2) Got a better experience in gnome when opening a terminal and running syndaemon -d in gnome. However, that seem to freeze the mouse slightly too long after I have stopped typing (will test the hacks in this thread). The unity version works much better. My question is, what differers in default input settings between gnome and unity on 17.04? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1351772 Title: "disable touchpad while typing" doesn't work Status in OEM Priority Project: Triaged Status in unity-settings-daemon package in Ubuntu: Confirmed Bug description: When selecting "disable while typing" under the touchpad section of the "Mouse & Touchpad" preferences, nothing changes, the touchpad stays active while typing. I can rapidly type multiple characters with my left hand and continue to move the cursor with the touchpad with my right hand. I can see from my processlist that syndaemon is running with the following options: 2185 ? S 1:31 | \_ syndaemon -i 1.0 -t -K -R First, the -t option isn't what's expected with this setting, it should disable the touchpad entirely. Also, it doesn't seem to even do that correctly, as I can definitely click the touchpad while typing as well as moving the cursor.
