[nouveau] XFCE freeze

[Joris]

It seems to randomly lockup.

Often, I am able to scroll the mouse pointer without being able to interact with the desktop itself.

If the mouse pointer is moving then it's not Xorg that has frozen. Because Xorg moves the mouse pointer. It sounds like only your shell has frozen.
