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 fixed it by going to displays setting (write dis in search bar) and than turned off the "`unknown display"`. U see in displays setting two displays in the middle of picture in settings. One is built-in-display another is unknown. Choose unknown by clicking on it on the picture and take the button next to the "Unknown Display" from on to off. Tada
Have you tried this:

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

```

and it might work fine this way.
