Default Re: ArchLinux, xorg 1.7, Nvidia 190.42 => segfault

I applied the just reported patch to my git master xserver sources and reinstalled and subsequently reinstalled Nvidia 190.42. On restart, I have the same problem with xinerama, namely, while graphics is fine on both screens, the mouse behaves properly only on Screen0 (when I move to Screen1 it jumps around wildly and I SIGSEGV after a while [a bug report has been posted on this forum]).

On a hunch, that this was some simple arithmetic issue with dealing with the mouse x offset,
(e.g., an unsigned int being used instead of a signed one), I switched the sense of the two screens. That is in Xorg.conf

Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" RightOf "Screen1"
Screen 1 "Screen1" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
EndSection


I changed RightOf to LeftOf. Everything now works, (although I'm going to have to switch the screens physically of course.
