Bug Description

Here at work we are upgrading from Ubuntu 12.04 to Ubuntu 14.04. After that upgrade, when I turn my pc on, the displays order are wrong (the left one is on the right, and the right one is on the left).

I try to change it on configuration and it works for the session. But if I logout and login again, the configuration is lost. Btw, it gets saved on unity.

I don't know if this has anything to do but, we have some dconf problems since our /home is actually a nfs mount. We worked that around with this:

I am experiencing the same issue. Not only does the configuration with the gnome-control-center not persist, but when using xorg.conf (Using Nvidia drivers) the layout is also not honored.

A workaround for this is manually using xrandr to set the layout of the screens. I have added the xrandr command to my startup applications for now.

I have the same issue as well.
With 13.10 everything was fine. Yesterday I did a fresh install with 14.04.

I tested both (nvidia-drivers and X.Org-Drivers (currently running).

I also noticed the following - my system starts with the following display order:

Display 1 (primary) - Display 2

When I switch the primary bar in the 'display settings' to Display 2, it works for the session, but after a restart the display order is:

Display 2 - Display 1 (primary)

Moving the primary bar has never affected the display order before...

@Sebastian: When I run the xrandr command in the terminal after everything started up it works fine. When I implement it as a startup application Display 2 is broken (no background and windows are not displayed properly) .. maybe it's an issue with the Xorg-Drivers, will test it with Nvidia again...

Changed in ubuntu-gnome:
status: New → Confirmed

@Daniel: I added a "sleep 2" to the top of my script:

#!/bin/sh
sleep 2
xrandr --output DVI-D-0 --mode 1920x1080 --pos 0x120 --rotate normal --output HDMI-0 --mode 1920x1080 --pos 3840x120 --rotate normal --output DVI-I-1 --off --output DVI-I-0 --mode 1920x1200 --pos 1920x0 --rotate normal --output DP-1 --off --output DP-0 --off
