Comment 4 for bug 1521000

Given an nVidia card driving 2 displays (one laptop display, one LCD on DVI), configured for dual display (over and under), the settings are correctly enacted when XFCE first starts from boot, but thereafter, if I suspend the computer and restart, the settings are reset to one monitor (external display).

I have configured the desired settings both in nVidia's control panel and in XFCE's settings, but they are ignored.

I suspect that XFCE is incorrectly assuming the external monitor was just plugged in when the resume happens, and is incorrectly switching to just that monitor.

This *used to work* back on older versions of XFCE, where XFCE didn't try to manage multiple monitors, so only the nVidia driver was handling the issue. Now that XFCE wants to control this, it is broken.
