xorg.conf for SPARC graphics [PSARC/2008/251 FastTrack timeout 04/16/2008]

[Alan Coopersmith]

I'm on vacation this week, so not following all my e-mail closely, but
I don't see any justification for why SPARC needs an xorg.conf by default
instead of following the x86 model of autoconfiguring by default with no
xorg.conf file.

If you must have an xorg.conf, how are you going to keep it in sync with
changes to Xorg that would require updates to the defaults?

I'd recommend this case be withdrawn, and the defaults set correctly in
the Xorg binary, as we do on x86, and as the X server team has always
believed we'd be doing on SPARC as well, until this case surprised us.
