I'm running an i7-4770K with an Nvidia Geforce 210. The Intel HDMI port is connected to a 4k display while the Nvidia dual-link DVI port is connected to a 2560x1600 monitor. I'm running Ubuntu 13.10. By default both monitors are recognized in landscape mode and things seem to work. When I attempt to rotate the 2560 monitor to portrait mode using xrandr, X crashes.

I'm also experiencing crashes when rotating the display powered by an Nvidia GeForce 420 Go and then going through a suspend/resume cycle. I'm using the proprietary legacy driver. Possibly related?
