Hi Kevin 

Thanks for your comments. I totally agree with you on eliminating other
possible causes of failure. But the thing is, same T5550, DVI-VGA adapter and
crt monitor setup works with via-opensource driver. I am just changing my
driver and rebooting. Two log files "Xorg.0.log-via-opensource-VX900-crt" and
"Xorg.0.log-openchrome-4.0.0-VX900-crt" in my attachment comes from just same
HW setup. My life experience says that even this can not totally eliminate
possibilty of HW failure or other casues of problem but it seems less likely. I
wish Frank or Justin can test it with a crt. 

Regarding other questions, I have tested DVI-VGA adapters with other devices. I
did not test direct DVI monitor connection to T5550 as I do not have one to
play with at the moment. And no, unfortunately there is nothing in BIOS of
T5550 regarding display device connection, its totally ignorant on this. 

Lastly, do you see any possibilty in the driver side to (re)implement a
fallback setup if no monitor detected. What I mean is, acting as if there is a
VGA monitor detected at DVI-I port supporting (some ?) standart VESA modes. I
do not know if it is possible or worth to work on but just my two cents. 

John
