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: 
A dirty hack I do (which surprisingly works for me) is to open terminal by pressing `Ctrl+Alt+T` and then type `ls` then the mouse shows in 1-2 seconds.

That said, the normal way that works is to restart the mouse driver. This solution also works when the mouse pointer is misbehaving (like flickering randomly out of control). You restart the mouse driver like:

```
sudo modprobe -r psmouse  # disable the driver
sudo modprobe psmouse # enable the mouse driver

```
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).
