I'm having a hard time on getting to work my laptop's touchpad. The problem emerged after I installed the packages to make Netflix works with Ubuntu. I followed this tutorial at www.techtudo.com.br for the Netflix installation, and it installed a bunch of packages, including Wine, etc (the tutorial is in portuguese, but can be translated easily through Chrome).
After that, my laptop's touchpad stopped wornking. On my laptop's keyboard, there's a button that enables/disables the touchpad. What I realize is that, no matter how many times I push this button, it always returns to me a graphic notification showing that the touchpad is disabled.
If I run this command:
sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps
The movement through the touchpad starts to working, but it still doesnt recover the toggle functionality of the touchpad blocking button on the keyboard.
Also, if I plug a USB mouse, the pointer movement works fine through the external mouse.
Any ideas on how to solve it?
