If you have another machine available.......

Install x11vnc on the machine that's not outputing correctly and open
the firewall port you'll use to log on via vnc (default is 5900)

put it into the mode that's causing the problem

remote ssh into it from the other machine

from within the ssh connection run x11vnc on it using a command like

x11vnc -auth /var/run/gdm/auth-for-gdm-xx443882 -display :0 -noxdamage
 (read the manual to see where the -auth token is on your distro)

in a separate command session on the 'new' machine log onto the
'faulty' machine with a command like

vncviewer 192.168.1.100

If you get a graphics image on the new machine you can then play
around to get the output working correctly

The reason to use x11vnc?  Over a wired connection it's fast enough to
see a TV image remotely (OK it's going to be terrible latency....and
only maybe one in five frames.....but you can see if it's working)
