I would look in the X server logs. The location depends on your distro, <br>
but one common location is /var/log/Xorg.0.log. (Substitute the correct <br>
X display ID for "0".)<br>
<br>
My guess is that you could be running out of memory due to the much <br>
higher amount required for that resolution.<br>
