I have a Dell Inspiron 5110 laptop. When I press the keyboard shortcut to disable the touchpad (
Fn+F3) it shows this in the corner of the screen:
But it does not actually disable the touchpad. This works perfectly on Windows. In fact, other than the notification, it doesn't seem to do anything: The light on the touchpad doesn't come on (it lights up when the touchpad's off under Windows) and the notification always shows the same image, like the computer doesn't even know it's supposed to be disabled. Is there a way to make this work right?
Update: I followed the instructions on getting hardware details & couldn't find anything that looked relevant. Here are the contents of /var/log/dmesg and /var/log/udev; I didn't know what to look for in them.
