gnome-display-properties does not display EDID info

[CatKiller]

Binary package hint: gnome-control-center

The majority of resolution problems in the Ubuntu forums appear to be caused by incorrect or missing EDID information. Either the monitors are not generating this information or the graphics cards are not passing it on. Having a simple display of the information that is being used to calculate the available resolutions would help the user to determine the cause of their resolution problem.

Ideally, this information should be editable, to enable the user to put in the values from their monitor manual. This should automatically set HorizSync and VertRefresh values in the Monitor section, and set UseEDID to False in the Device section, of xorg.conf, or wherever the new tools set X configuration values.

For the majority of users, this information would not be necessary, and would simply be informative, since their resolutions will have been automatically picked up and set. For those users where this had not happened, it would be an invaluable tool to troubleshoot their problem and to fix it without having to learn about manually configuring X or interpreting the text of the log files.

Displaying the EDID is pretty trivial, but probably wouldn't be very meaningful to most users. It can also be obtained via xrandr --verbose, or via the /var/log/Xorg.0.log, or via read-edid. I'm not convinced there's much value to also having it available via the GUI, but wouldn't turn aside a patch that implemented it.

Changing your EDID settings on the fly is a different problem, and covered by other feature requests elsewhere, and needn't be considered to add to gnome-control-center (indeed, it has no facilities for modifying xorg.conf).

the request is not specific to edid and a duplicate of bug #240916
