Does disabling compositing or tiling work around the problem?

Please attach the output of

xrandr --verbose

when both monitors are enabled.

If you ssh in, is the X server (and goban, ...) process still alive? If yes,
can you attach gdb to the X server and get a backtrace?

Would a newer version of this help by any chance?
