I installed Linux Mint 16 a few days ago on my Netbook. The touchpad didn't turn off while I was typing, so I dug around for a way to make it do so.
It turns out you can enable this feature on the "Mouse and Touchpad" configuration app (just search for that string among your applications) on the Touchpad tab. However, this default setting didn't work for me, because it turned off the touchpad for two seconds every time I typed something. For me, that was way too long.
(Note, in the following setup, I set my delay to 0.25 seconds. Feel free to change the 0.25 in the command in step 5 to whatever you want.)
Thus, it was a more manual configuration for me. Here goes:
- Run "Session and Startup". Again, you can just search for this from the "Start Menu" for Linux Mint.
- Go to the tab "Application Autostart".
- Click "Add"
- Type a name like "Synaptic Daemon", add in some comments about what you are doing in the description field, like: "Turn of touchpad while typing"
- In the command window, put:
syndaemon -d -i 0.25 -K -R
- Click OK
- Make sure that the entry you just created has a little "x" in the box to the left of it.
- Click close.
- Restart your system.
Now your touchpad should not accept input while you are typing. Almost immediately after you stop typing, it should again respond to your movements.
