The bug is that when no EDID information is available, the default resolution options top out at 1024x768. This is not usable on most modern systems. It would be very easy to provide a list of standard 4:3 and 16:9 resolutions so that if it can't be autoconfigured, a user can at least use the gui to choose something *close* without having to generate an Xorg.conf.
To address the minimum criteria for a complete bug report, I reiterate from my initial post: 1) I created a system that used a DP->DVI adapter. No EDID info was generated. 2) I expected to be presented with a list of common resolutions in the gui. 3) The list of default resolutions topped out at 1024x768. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/769366 Title: Monitor prefs: poor resolution options when EDID fails Status in “gnome-control-center” package in Ubuntu: Incomplete Bug description: Binary package hint: gnome-control-center If EDID/DDC fails, the resolution options are too restrictive; an exhaustive list of resolutions should be available. Use case: I run my third monitor through a DisplayPort-->DVI adapter, so no EDID information is returned. I cannot find any way to set the correct resolution short of generating an xorg.conf.
