I have similar problems on i915. In my case I don't even have to have virtual resolution enabled to encounter the problems. The only dual-head that works is mirroring screens. After I get black screen with movable mouse pointer the server doesn't react neither to ctrl+alt+F<n> nor ctrl+alt+backspace (I have DontZap set to false so this normally works). I can ssh to the machine: sending SIGTERM to X process doesn't have any effect. Sending SIGKILL freezes whole machine. I'm attaching Xserver logs, config and output of lspci.
