Any way to disable touchpad on Dell Inspirin 17R?

[donsy]

I loaded 11.10 on my Dell Inspiron 17R and I've been very satisfied so far except for one MAJOR annoyance. The touchpad is enabled while I'm typing and I can't disable it. Here's what I've tried so far:

• Bios -- no option to disable pointing devices.
• Hotkey FN-F3 -- Doesn't work in Ubuntu (works fine in Windows).
• System Settings > Mouse and Touchpad -- no option to disable touchpad while typing.
• syndaemon -- has no effect.
• synclient -- has no effect.

This is driving me crazy, Is there anything else I can try?

Amazing. It works for my netbook Samsung N210 with Xubuntu 12.04:

You have to create the file "blacklist-touchpad.conf" with root privileges in "/etc/modprobe.d/" and add to it this single line: "blacklist psmouse". If you need to enable it again, just comment the line like this: "#blacklist psmouse".

Step by step for beginners:

1. Go to your terminal and open Leafpad with as super user:

sudo leafpad

2. Write in the new page the following line:

blacklist	psmouse

3. Go to "save as" and save the new file into the following directory: /etc/modprobe.d/ and name it like this: blacklist-touchpad.conf

4. After saving it, reboot your machine and the touchpad will be deactivated.

If you need to activate it again:

1. Open the file as super user:

sudo leafpad /etc/modprobe.d/blacklist-touchpad.conf

2. Comment the line by adding a "#" simbol to it. The line should now look like this:

#blacklist	psmouse

3. Save changes and reboot.
