My secondary display with HDMI was not working with Ubuntu 12.04. So when the new version came I thought I would just try it out and bam, it worked.
Now the secondary display which I use as an extended desktop is working when connected via HDMI cable. The only problem is, it displays the mouse trails if I move the mouse fast.
Also the same happens if I drag the windows. I have tried installing bumblebee, but that simply removed the extended display support and it stopped working.
Can anyone please tell me if installing the nvidia drivers will resolve the issue? If there is any other solution please let me know that too!
