Desktop streched across both screens

[sjp333]

Intel HD graphics controls the internal display and the nvidia card handles the display port out. When trying to utilize a dual monitor setup the output of the desktop looks like its been stretched across both displays. It appears like the resolution is very low and the mouse pointer is incorrectly calibrated with its location on the screen.

The bug was reproducible and there was no improvement.

sjp333, to see if this is already resolved, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

[sjp333 (sjp1796)]

In 16.04 the stretching issue is resolved. However, the display manager is still a bit buggy. It switched to mirrored displays when I tried to turn on both displays. However after exiting the manager and re-opening it. I was able to get both displays working correctly. Another issue is that the other display is a HDTV and I need to adjust the underscan on it. When I do that it also underscans the laptop's screen.

[sjp333 (sjp1796)]

^ I was using nvidia settings to adjust the underscan which only "saw" one display being DFP-0 (The HDTV).

>"In 16.04 the stretching issue is resolved."

Would you need a backport to a release prior to 16.04, or may this be closed as Status Invalid?

>"However, the display manager is still a bit buggy. It switched... Another issue is..."

These would be different problems for different reports. Please file a new one, one per unique issue.

I am fine staying on 16.04. Thank you for your help.
