Only when using the nvidia drivers, after logging in, the cursor is not drawn on the screen. I can see its effects while moving the mouse or touchpad, as items on the panel gets highlighted, or my unity panel becomes visible. I can even click on them and everything else works.
Workaround:
Move to vt1 (CTRL + ALT + F1), log in, and restart the lightdm server:
sudo service lightdm restart. Now log in again through lightdm. This works most of the time.
