What about "special" cases, were I need xorg.conf, e.g. support for
stereo or dual monitor layout?

How is that a special case? My T60p has two external monitors attached
to it, and the gnome display properties applet shows the two external
displays as well as the internal LCD. All without any xorg.conf

Of course there are probably corner cases where the settings picked by X
aren't optimal. I guess the argument is that in these *specific* cases,
it should be possible to hand-tune the configuration using the existing
GUI tools, and that cases where manual configuration change is necessary
are rare enough for that to be a sufficient solution.

I have to say here that the auto tools are working VERY well for me on
11.2. I've tried various monitors, and even a projector (some call
them beamers), and it got it right every time. When I wanted to
adjust the auto selected resolution to something different, I just had
to use the Display settings in the KDE4 Configure Desktop and I could
select alternate resolutions. I've even had the case where a game
crashed and left the desktop at a low resolution... setting it back to
the correct resolution wasn't hard at all.

I do have one more acid test for it though :-P My LCD TV which in
theory can run at high resolutions... 1900x1040 or something like
that, but sax2 could never configure higher than 1024x768 no matter
what I did with it. Maybe I'll try it this coming weekend.

I have a similar experience when using my external digital monitors via the
VGA port of my X60 (i945GM). xrandr and the GUI tools never report the
screen resolutions until I tell xrandr about it with gtf, --newmode and --

Is there an established way to troubleshoot this?

Is it a bug in...

a) my monitors (no EDID?)

b) the intel driver?

c) Xorg?

Is it my fault because xrandr can't detect monitor resolution when using the
external monitor?

Is it ?
