Ubuntu 14.04 no cursor after fresh instalation

Question

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.

Solution 1

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

Solution 2

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.

Solution 3

Do following steps:

1. Open terminal (Using the Dash or by pressing Ctrl+Alt+T)

2. Update apt with the command:

   dconf reset -f /org/compiz/
   

3. After that, run the following command to restart Unity:

   setsid unity
   

4. To get back the default set of icons released Unity pain, run the following command, and then close the current session and log in again:

   unity --reset-icons
   

Now your desktop Unity and the effects of compiz should be back to the original settings.

Solution 4

In certain cases, this issue seems to be related to a lightdm bug. Try running:

sudo service lightdm restart

Solution 5

I had the same problem. You can fix it manually. Open System Settings > Displays. In the Displays window, you will see an Unknown monitor. Click it and disable it.

I found the solution from the following: Mouse cursor flickering and disappearing

While I am using 14.04 and the above link is for 13.10; it worked for me! ;)

this is my case too. I'm used to do most things without mouse (I use emacs and I start it with Super-3) so I wait long enough to notice that after like 2 minutes the cursor will appear anyway.

"Click it" - how if you can not see the mouse cursor?

The solution is no longer functional on Ubuntu 14.04.

Works for me on 15.10 multiscreen (2 monitors + laptop screen). The cursor was invisible only on one screen and visible on the others, but it was changing from time to time so that i had to change the elements i was working on to on of the screens that displayed cursor. Thanks !

Worth mentioning that unity --reset-icons will remove all the icons from your dash sidebar, and log you out
