immutable inexplicable screen switch

[keepitsimpleengr]

Binary package hint: xserver-xorg-video-nv

Shut down system, next day booted and screens were switched. The former screen 0 is now on the smaller second monitor and the former screen 1 is on the larger main monitor. No changes were made except shut down and restart.

How do I fix this and how do I keep it from happening again?

10.04 Linux-x86_64 clean install, nvidia 195.36.24, Server 11.0 1.7.6, nv-control 1.22, Geforce 9400GT

Was DFP-0 Screen 0 Large main DFP-1 Screen 1 small second
Now DFP-0 Screen 1 Large main DFP-1 Screen 0 small second

Well, I haven't fixed it, but I did find a work-around. It is astonishing, but at least it worked!

1) From terminal: sudo nvidia-settings
2) Under "X Server Display Configuration" arrange Layout with larger screen to left.
3) Press "Configure..." button and select TwinView.
4) Press the "Save to X Configuration File"
5) Restart computer (or X server)
6) From terminal: sudo nvidia-settings
7) Press "Configure..." button and select Seperate X Screen.
8) Press the "Save to X Configuration File"
9) Cross your fingers
10) Restart computer (or X server)
