Public bug reported:
Every time I reboot or log out and back in again, The layout of the displays is
incorrect.
Correcting the layout is a bit 'hit and miss' as the changed layout is not
always applied correctly.
There was a massive improvement after upgrading to 16.04 from 14.04.
Previously, the upper display did not render pixels consistently. The
upgrade corrected this.
The upper display (29") is connected to the NVIDIA Corporation GK107
[GeForce GT 740] display card and the lower display (23") is connected
to the on-board Intel Integrated Graphics Controller.
I hope this information is useful. Thanks for your efforts...
