Default Screen 3 and 4 toggling on X restart with 275.21

We have HPZ600 Workstations with 2 Graphic cards (FX580) connected to 4 screens.

On restarting X the screens 3 and 4 toogle, means 3 gets 4 and 4 gets 3. Restarting again and 3 is 3 4 is 4. See below (-> = x restart):

1 -> 1 -> 1 -> 1
2 -> 2 -> 2 -> 2
3 -> 4 -> 3 -> 4
4 -> 3 -> 4 -> 3

This is happening since Driver Version 270. See appended bug report.

Using ports 1(DVI) and 2(DP) on the second card makes no difference.

rdeger, when you say that this happens since driver version 270, do you mean to say that previous versions did not swap screens? If so, can you give an example of a specific previously working version? Thanks.

danix, we have the problem with the toggling screens (3 and 4) since Version 275.21. Before 275.21 on X restart we had the following behavior:

1. Restarting X for example via ctrl-alt-backspace
2. NVIDIA LOGO gets displayed on screens 1+2, screens 3+4 show nothing (black)
3. Thats it nothing happens (crash)

That means that I cannot say that the toggling Problem did not exist before 275.21.
