Comment 49 for bug 3731

Bryce: The X autodetection is not a solution for now. It is so poorly designed it is unusable.

It does not work by commenting out sections in the config file. You have to *REMOVE* the config file *COMPLETELY*.

This means that many settings for which there are no reasonable defaults break.

However, I tried it for the sake of experimentation when I was configuring X for Ati Radeon 9200 + Sony G200. The readouts from the card are complete, the monitor is fully identified including all the modes. X says the first detailed timing is the preferred mode in the log but it chooses some 60Hz mode for this CRT monitor. It probably chooses the largest over the one marked preferred or one that has reasonable refresh rate.

Even if it worked this way of configuration is useless because it does not allow to specify *anything* in the config file (keyboard layout, server options, dri options, font paths, graphics driver options, ..). Many of these options could be set or worked around in gdm scripts but some cannot.

For one, on Matrox cards the default is hardware cursor which is broken. Another recurring problem is the option to use DDC readings defaulting to off for some drivers.
