I installed Ubuntu today and since the first start up I have a problem with the mouse cursor.

It starts randomly disappearing and flickering a lot.

I have searched for a solution on Google and here but didn't find anything.

Welcome! How is your mouse connected (USB maybe)? Try with another mouse device and see what happens. Also you may try plugging into another port – Lucio Oct 17 '13 at 19:04
Its happening in 14.04 as well and this trick saved my time. – Nagendhiran Apr 13 '14 at 3:33

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.

There is no unknown display for me. But I can see 2 built in display in red and green color. I tried disabling one of those alternatively but that also didn't solved my issue. Please help – Vishal Vijay Nov 22 '13 at 5:16
Ho sorry... Disabling the green built in display solved the issue. Thanks – Vishal Vijay Nov 22 '13 at 5:24
