i915 dual head configuration (FC5 – F7 doesn’t work yet)

I posted some queries about getting dual head working with my laptop, which uses the Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller, aka i915GM.  Under FC5 the i810 X.org driver supported dual head AND TV-out.  But I’m having a problem getting dual head working under F7 with either the i810 driver or the experimental intel driver (see my previous post). 

One of the folks on the Boulder Linux User Group mailing list asked if I could post my config files for dual head that worked under FC5, so here there are:

xorg.conf.lcd-only
xorg.conf.lcd-and-lcd
xorg.conf.lcd-and-tv

In reality, these are all just slight variations on the xorg.conf.lcd-only configuration, with a different ServerLayout defined to get the configuration of interest.  I’ve heavily commented these config files for use with the i810 driver.  I don’nt know why they don’t work with the F7 version of the i810 driver.  At the moment, the best I’m getting from them is segfaults from the X server.

Right after posting this I went to the MythTV Users mailing lits and searched for i915.  Turned up a bunch of information that might be useful to get this working:

It just sorts itself out. If you look through the X log you will see it sorting itself out, figuring out what the monitor can do and generating possible modelines for itself.

I'm only interested in doing the native resolution of my panel so I haven't been motivated to do any more futzing with it.

Remove your xorg.conf file entirely and see what happens.

So maybe I need to give these a try.
