Just a little update....for any that are interested
After much Googling I ran the following from the command shell:
X -config /root/xorg.conf.new
At which point the monitor went blank and I was forced to reset.
This confirms that monitor/display card is the problem??
I have read somewhere that I can use the following to enter an 'interactive' mode for changing displays etc:
Couldnt get this to work however....
Can anyone tell me please how to edit my /xorg.conf.new file as I'm pretty sure this is the problem? But, hey, I'm only 2 days old
(BTW my PCIe = 6600, monitor=Diamond pro750sb)
