Bug Description

Since upgrading from Ubuntu 15.10 to 16.04, Unity is now shown across both my monitors in a hard to use manner: unity dialogues, such as the log-out and shutdown popups, are displayed centered between both monitors, so the left half is on one monitor, and the right half on another. Also, the unity top panel indicators and clock used to be on both monitors, but are now only on the right monitor.

More info since it is likely relevant:
I have a Dell laptop with an NVidia Prime GPU and Intel built-in GPU. This laptop has always been trouble configuring for dual monitors. The nvidia-settings controls only shows one monitor, though it is supposed to show two. I have never been able to get a working xorg.conf for the two monitors, despited 2 days of trying (and I am a software developer well versed in reading docs). The instructions in the nvidia docs simply don't work as stated for this hardware (Dell XPS 17 L702X). Purging all graphics settings doesn't help. Upgrading to a newer nvidia driver didn't help (I've tried the latest official nvidia package as well as one newer). As a result, I've been using an xrandr command and compiz display settings since Ubuntu 15.10. This worked perfectly in 15.10. But, as stated, the unity top panel and dialogues are not working properly in 16.04.

I tried Nvidia 361.42 and 364.19 from the PPA at http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu.

The xrandr command in use is:
xrandr --fb 3520x1080 --output HDMI-0 --preferred --primary --mode 1920x1080 --pos 0x0 --panning 3520x1080+0+0/3520x1080+0+0/0/0/-3520/0 --output LVDS-1 --mode 1600x900 --pos 1920x180 --panning 0x0

(I know the fb sets up a wide virtual screen, but as stated, in 15.10, that worked perfectly for unity)

In compiz display settings I have the following "Outputs" set:
1920x1080+0+0
1600x900+1920+180

It would appear in 16.04, Unity ignores the compiz outputs whereas in 15.10 it does not. But that's just a guess.

Sorry I cannot get a screenshot of the dialogues. They seem to block Ubuntu's screenshot program due to their modal nature.

the result of get_screens.py is:

('# monitors: ', 2)
3520x1080+0+0
1600x900+1920+180

------

This clearly shows the issue. The first monitor res should be 1920 wide, not 3520. Any suggestions on how to fix it?

Ok I'm targeting xorg and gtk/gdk too. I'm not at home right now and I cannot test it on a double monitor setup. I'll work on it next week. Thank you.

seems like it's handled as a big screen rather than 2, do you get the issue if you configure the screen using the desktop settings?

Yes.

Additional info:
-The "Detect Displays" button in the "Displays" window shows "Built-in Display" and "Samsung Electric Company 27" both in the top-left corner of the left monitor, overlapping each other.
-I, if I remember correctly, if I do not use xrandr to nullify the panning, that is if I use the Display window for setting the displays, the left most monitor incorrectly pans to the right when the mouse reaches the right monitor space. So the left most monitor acts like it has both monitors' display space.
