The new Intel driver doesn't need 915resolution anymore since it recognizes wide screen resolution on its own and Xinerama isn't supported anymore because it was replaced with xrandr.
I guess the problem is your old xorg.conf. Please regenerate a new one with the command "sudo dpkg-reconfigure xserver-xorg" and restart X.
If it still happens please provide the following information:

/etc/X11/xorg.conf
/var/log/Xorg.0.log
output of lspci -vvnn
output of sudo ddcprobe
output of xrandr

Maybe the Virtual limitation could be a problem. How do you want to configure your second monitor? Clone mode, left or right of or something like that?
