I have the same issue and the trigger seemed to be moving from an AMD to an Nvidia graphics card. Switching to console (CTRL Alt F1) and back fixes it but can cause some issues with any graphical applications running at the time. I am also using the Ubuntu automatic Nvidia driver that appears to currently be one version behind the one on their website.
