A Xorg log file of failing session

Starting with "[86024ceef015ffe31a204cc5bc6c326a19363ff1] glamor: initial
support (no dri)" is not possible to configure a secondary monitor while
running KDE 4.14.2. 

Steps to reproduce:
Version A:
 * while a KDE session is open, plug in a secondary monitor
 * use KDE display configuration tool to enable second monitor
 * X11 server gets restarted -> KDM window appears

Version B:
 * start system with a secondary monitor attached
 * observe how system is running in a "clone" mode (there is output on
secondary monitor)
 * log in in KDM
 * observe how X11 gets restarted -> KDM window appears

Solution - use any revision before 86024ceef0

Unfortunately log files are empty - there are no meaninful messages that could
shead a light on the issue. No crash is recorded, xorgsession-errors are just
indicating on IO error while connecting to X11;

There is some issue with EDID, although KDE monitor configuration displays
correct information. dmesg snip:
