Re: ArchLinux, xorg 1.7, Nvidia 190.42 => segfault
For me, downgrading the packages
xorg-server (1.7.1-1 -> 126.96.36.1991-1)
xf86-input-evdev (2.3.0-1 -> 2.2.5-1)
xf86-video-vesa (2.2.1-1 -> 2.2.0-1)
resolved the problems with xorg crashing when moving the pointer from one screen to another with a separate X screen setup. I am still using the current 190.42 nvidia driver though which seems to work alright for me so far. Seems to me that this is not even a nvidia driver problem.
