However, if sax2 wasn't used from the beginning, there would be no static configuration for the better monitor, X would automatically determine the (probably) right settings instead. And if you change the monitor, X simply picks fresh settings appropriate for the new monitor.
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 native screen resolutions until I tell xrandr about it with gtf, --newmode and -- addmode.
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?
Most likely a driver issue.
Unlikely unless you already use KMS, i.e. you load i915 module with option "modeset=1" ("i915.modeset=1" as boot option).
