Screen size on dual screen when second screen is at left

[Charles Brunet]

Lenovo W520 (Nvidia Quatro 1000M + Intel Sandybridge, optimus, VGA port connected to Nvidia card only).
Ubuntu 14.04. nvidia-prime 0.6.2. Unity.

If my external monitor is located at right. everything is fine.

If my external monitor is located at left:
- maximizing window causes it to fill both screens
- moving my mouse cursor from external monitor to LCD screen cause the display on the external monitor to scroll. When my mouse is on the right side of LCD screen, both monitors display the same thing.

With external monitor on top of LCD screen, maximizing occurs only on top external monitor, and weird scrolling occurs as well when going to bottom LCD screen.

With external monitor at bottom of LCD screen, everything seems fine (except I cannot drag window from bottom to top because of maximizing behavior when I bring a window at the top of the monitor.)

I guess there is the assumption somewhere that the laptop screen is located at top / left.

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm this problem. Top and left alignment are fine, right and bottom alignment result in the described scrolling effect and wired window maximizing.

I'm on a Lenovo T420 with NVS 4200M and Intel Sandybridge.

Same problem for me, exactly.

Dell XPS14z (external monitor is using the DisplayPort output of my GeForce GT 520M).
