Ubuntu 14.04 no cursor after fresh instalation

So I'm having a problem after installing Ubuntu 14.04 on my HP Pavilion dv6-3160sp.

The problem is that after the booting to ubuntu the mouse/cursor simply vanishes, and also if I try like right click it doesn't do anything, so it's not "invisible" I think.

But when I was "Trying Ubuntu" before installing I didn't find any problem, the cursor was normal.

The iso that I'm using it's the official "ubuntu-14.04-desktop-amd64".

I tested with the touchpad and a normal mouse, with no results.

I tried to use the command:

gsettings set org.gnome.settings-daemon.plugins.cursor active false

but nothing worked.

I was having a similar problem after switching users. I was able to get the touch pad to work by reloading the kernel module:

sudo modprobe -r psmouse
sudo modprobe psmouse

I had a similar problem - after a kernel update, the display comes up fine and the cursor is invisible though it does work - I can move things around if I'm very careful.

This was solved by simply logging out and back in.
