Bit of progress.
Using startx I got - a list if errors.
Failed to load module 'glx'
Failed to load module 'dri'
Failed to load module /usre/lib/xorg/modules/linux/libfglrxdrm.so
Then a few more.
And at the bottom of the screen -
Fatal server error
no screens found
Yesterday when I installed I had the monitor hooked up & the tv was connected with hdmi. This morning when I booted the tv was disconnected from the power. If that means anything. The power is on now but still nothing.
