Comment 9 for bug 148056

I fixed this by deleting the /etc/X11/xorg.conf as suggested above (actually, I renamed it with 'sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.broken', although all of the xorg.conf backups were deleted after restarting). This allowed me to use the displayconfig-gtk, which I neglected to mention wouldn't start before deleting the file. After the system restarted, my video card driver and screen resolution were set to an incorrect, unusable setting, but after correcting these settings I have the display back on my TV.
