Comment 35 for bug 207409

I get periodic black screens (out of range), and of course have the same issue that dpkg-reconfigure xserver-xorg (and displayconfig-gtk) don't allow me to reset in any sensible way, nor does my old gutsy xorg.conf help. Having done a lot of searching for this particular bug, I can confirm it's leading to many dozens of mostly unresolved support requests (which I'll be adding to once I'm sure I've not got an exact duplicate of another one).
