Comment 4 for bug 1531555

I have similar problem on ONE of my computers.

Same kind of error message but in my case the screen will switch to texxt mode and the cursor will blink in a strange frequency, like it is blinking every time a new process is started above.

On this particular computer I am running funtoo current, xfce4, lightdm 1.19.0 and gtk-greeter 2.0.1-r1. If also run kernel 4.6.0 and nouveu drivers for my nvidia card.

On the laptop also running funtoo current but have kernel 4.6.2 and Intel Core I5 Haswell with the very latest haswel graphics things works well. It have the same version of xfce4. lightdm and lightdm-gtk-greeter.

On my second laptop with same setup it also works well. That is an EeePC with atom processor and a GM500 or similar graphics. Xfce and lightdm is same.

Question is why it fails on the workstation and not on any of the laptops with the same os, Xfce4 and lightdm.

How can I help fualt findning? Beside the very same message as shown above?
