Created attachment 380096 [details] xorg.0.log I have an Asus laptop with Nvidia GeForce GT 630M , I'm using Nouveau drivers. Updating from xorg-server-1.14.3 to latest version (xorg-server-1.15.0) causes X failing to start with Segmentation Fault.

Server aborting The same problem appears in xorg-server-1.14.5. I don't use any configuration file except /etc/X11/xorg.conf.d/30-keyboard.conf . The only solution for me is downgrading to xorg-server-1.13.4-r1 (1.14.3 has been put out of the tree).
