Disable touchpad while typing not working on ubuntu 18.04

[arcety]

I really love ubuntu 18.04 but something is driving me nuts. Everytime I'm typing and i accidentally touch the touchpad mycursor jups. On another post I found that this behavoir can be solved in two ways:

• By using syndaemon
• By using the touchbar-indicator plugin

But on my system both methods seem to fail. For the touchbar-indicator I just enabled the auto disable touchpad option but that doesn't do anything. Then I configured syndaemon as a startup application like this:

/bin/bash -c "sleep 15 && syndaemon -i .8 -K -t -R -d"

If anyone knows what I can do about this behvaoir please tell me since I'm going mad.
Thanks a lot in advance, Greetings, Rick

In a default 18.04 install disable-while-typing is enabled, the timeout seems to be 2 sec (barely in gedit, almost immediate in firefox, i.e cursor comes back right away
The setting is in dconf-editor > /org/gnome/desktop/peripherals/touchpad
If one wanted to raise the timeout in may need to be done in libinput somehow.

Thanks for your reply it helped me narrow down the problem. I solved my problem as follows:

1. By using this forum post I fully reinstalled my xserver drivers.
2. I then reinstalled the drivers following this forum post.
3. I then added the following command to my startup applications:

syndaemon -i .5 -K -t -R -d
