    Almost immediately after starting a battle the display I was using closed and kicked me back to the login screen. A possibly enlightening snippet from /var/log/messages suggests a segfault may be the cause:

    Oct 29 01:40:39 salt kdm[2993]: X server for display :0 terminated unexpectedly

    Impressive. Which Linux distro do you use? And which graphics drivers?

    I had forgotten my go-to solution of disabling the steam overlay, doing so seems to have stopped the problem. It's unusual because when the overlay causes problems it mostly hurts performance or has the game hang, I've never seen a crash-to-desktop-and-then-crash-the-desktop issue before.
