If you still have problem, please file a bug with log attached according to http://intellinuxgraphics.org/how_to_report_bug.html.

xrandr -q shows exotic resolutions and If I run it sequentially it 
sometimes shows TMDS-1 connected and segfaults as if it would not stay 
enabled. Enable/true option seems not affect.
