This is a problem on my brand new Dell Latitude, equipped with Ubuntu 16.04.
Whenever I press a key, the touchpad scrolling stops working for a second or so. It is quite annoying, as I usually Alt-Tab and then immediately scroll, or type something on LibreOffice and then immediately scroll.
I thought this is related to "disabling touchpad while typing" feature, but I can use the touchpad for moving to cursor while typing, I simply can't scroll with two fingers.
I tried looking at my xinput props for the touchpad, but neither looked relevant. In particular, I tried to modify each property with "Timeout" in its name. I also couldn't find anything relevant in
After playing a little bit with "watch synclient", I figured out that each time I press a key, the property
TouchpadOff switches from 0 to 2 for about a second, and this means that during that time "only tapping and scrolling is switched off". So it is probably not a bug, but rather, it is defined somewhere.
Can you help me find where it is defined, so I can reduce the time a little bit?
