xorg.conf without resolution modes?


After a few months without having any need to do it, I recently made a couple of fresh FC6 installations. When, as usual, I opened xorg.conf to edit the resolution modes, I found that they were not there at all.
Have I been missing something in Xorg's recent evolution?

How can the X server know the resolutions at which to work since they are NOT specified in its main configuration file? Have those informations been moved somewhere else? Where?

Thanks a lot for any help

Xorg now gets it's information from the EDID data returned by the monitor, and calculates valid modes. The only time you need to override that is when the EDID data is invalid (some manufacturers put screwy information in the PROM) or non-existing (old monitor).

I thank you for your kind answer.
Now I understand the reason for such a slim xorg.conf.
However I don't think Xorg actually gets those EDID data from the monitor at every boot.
Can you tell me WHERE those information get saved in the system?
I know there is no need to edit them, just a curiosity of mine...

Thanks again

Yes, the data is read every time X starts. If you'd like to see the data retrieved (in human readable form), you can start X with:

Xorg -logverbose 5

The /var/log/Xorg.0.log will report the EDID data retrieved.
