Touchpad not working on MSi U130 after login in

Solution 1:

The problem could be caused by an IRQ conflict between your mouse and your touchpad. This is a Linux kernel bug (at least in 2.6.28) and as such it affects most distributions. An easy way to recover both mouse and touchpad functionality without having to restart your X server is restarting the mouse driver. Run the following commands in a terminal window:

sudo modprobe -r psmouse
sudo modprobe psmouse

I am currently using Linux kernel 3.0.0-16, so if this is indeed the same bug, I'm surprised it's still there.

Solution 2:

Installing the synaptics utility and changing settings didn't work for me. I found something that fixed it in a comment in a Bug report

1. Install dconf-tools (dconf-tools in synaptic package manager or dconf Editor in the Ubuntu Software Center)

2. Launch it, it's called "dconf Editor" (It's in the System group if you use filters)

3. Find the setting touchpad-enabled in /org/gnome/settings-daemon/peripherals/touchpad/ and enable it.

4. Quit the editor and you're done.

Note, this did not require a restart or logout/in for me, the touchpad started working straight away.
