Question: My mouse pointer became invisible after some updates after I upgraded to 15.04 from 14.10. 
In all standard settings the mouse pointer is activated (system settings, dconf...)
I also tried different cursor icons with no success.

The pointer is sometimes visible after I shut down and reboot the system. But only sometimes and I couldn't figure out a patterns why it sometimes shows up.

I found the following solution which did not work

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

```

Any help appreciated! thanks!

Answer: 
I have similar problem. Mouse pointer is invisible after system boot, even on LightDM screen. To bring cursor back I'm switching to virtual console (ctrl+alt+f1) and run command:

```
sudo service lightdm restart

```

After LightDM restart mouse pointer back to normal. I reported this bug to [Launchpad](https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1453538).
Have you tried this:

```
 gsettings set org.settings.daemon-plugins.cursor -KEY=s.cursor -VALUE=false

```

and it might work fine this way.
