Plans for dynamically re-configurable X server

[Alex Deucher]

Has anyone started working on this?  Is there an API in the works? 
Perhaps something like Xv attributes, only for the Xserver itself
rather than overlay specific?  The last time I brought this up was
prior to xorg, and as I recall, some of the powers that be at the
time, said there was something in the works, but I haven't heard
anything since.  xrandr covers some of the functionality, but it's not
fully functional, and it'd be nice to support more chip specific stuff
like enabling/adjusting/disabling tv-out, dualhead, power management,
re-run DDC, and other tweakable settings.  Most drivers could handle
it with fairly minimal work, but we need a system to interact with the
X server.   I guess one of the issues in memory management.  Ian is
working on a DRI memory manager and I think Alan H was working on one
as well.  While the current system isn't great, I don't think it
should be an impediment to adding configuration support.  All we would
really need is a current configuration validation function that would
enable/disable memory dependant features like the DRI, Xv, certains
depths/modes, etc. if there wasn't enough memory in the new
configuration.  Has anyone done any work on this?  Any thoughts? 
Ideas?  Let's kick off some discussion.

Thanks,

Alex
