Comment 105 for bug 1292398

This appears to persist in 17.04....I installed Ubuntu Server first, and then installed Xubuntu via Tasksel because I needed to do some additional setup before any display manager would be able to function. I also tried MATE and LXDE on the same system, and they did not appear to suffer from this issue. Thus it would appear this is specific to XFCE.

GPU is GTX 980M on an MSI GT72s laptop.

I also tried setting the monitor configs through the Nvidia control panel to no avail. It's not just session to session but actually even just letting the screens idle to sleep, the layout is bombed and I have to reset it when they are powered back on.

It also fails to detect my external monitor's max refresh rate 9 times out of 10 but I suspect that is a deeper, unrelated issue.
