This is a modified version of a patch we've been carry-ing in Fedora and
RHEL for years now. This patch automatically adds secondary GPUs to the
master as output sink / offload source making e.g. the use of
slave-outputs just work, with requiring the user to manually run
"xrandr --setprovideroutputsource" before he can hookup an external
monitor to his hybrid graphics laptop.
There is one problem with this patch, which is why it was not upstreamed
before. What to do when a secondary GPU gets detected really is a policy
decission (e.g. one may want to autobind PCI GPUs but not USB ones) and
as such should be under control of the Desktop Environment.
Unconditionally adding autobinding support to the xserver will result
in races between the DE dealing with the hotplug of a secondary GPU
and the server itself dealing with it.
However we've waited for years for any Desktop Environments to actually
start doing some sort of autoconfiguration of secondary GPUs and there
is still not a single DE dealing with this, so I believe that it is
time to upstream this now.
To avoid potential future problems if any DEs get support for doing
secondary GPU configuration themselves, the new autobind functionality
is made optional. Since no DEs currently support doing this themselves it
is enabled by default. When DEs grow support for doing this themselves
they can disable the servers autobinding through the servers cmdline or a
xorg.conf snippet.

DGAShutdown() walks every screen and attempts to reset the mode. That's
maybe a reasonable thing to do, although the explicit loop is certainly
a bad smell.
In ddxGiveUp it's called after we've torn down the vga arbiter - and in
fact most of the rest of screen state - which is... very very bad. The
other place it's called is from the Control-Alt-BackSpace handler, where
we don't even attempt to do vga arb setup, and where in any case we're
going to escape the main loop eventually anyway.
Move all that cleanup work inside DGACloseScreen. This means it happens
earlier in server teardown than previously, but not in a way you're ever
going to be upset about.

The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.
Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.
v2: Update to match v2 of the vnd import, and remove more redundant work
like request length checks.

The only way to get at xf86Info.disableRandR from configuration is
Option "RANDR" "foo" in ServerFlags, which probably nobody is using
seeing as it's not documented. The other way it could be set is if a
screen supports RANDR 1.2, in which case we set it to avoid trying to
use the RANDR 1.1 compat code. If the second screen is not 1.2-aware
then this would mean we don't do RANDR setup on the second screen at
all, which would almost certainly crash the first time you try to do
RANDR operations on the second screen.
Fix that all by deletion, and just check whether the screen already has
RANDR initialized before installing the stub support. If you want to
disable RANDR, use the Extensions section of xorg.conf instead.

Any code called from the driver ScreenInit may want to refer to

the DDX sees a new screen, the generic code needs to make sure that

initialization code.
This was found by running a driver which didn't bother to set this
value when the initial colormap was installed; xf86RandR12LoadPalette
tried to use pScrn->pScreen and crashed.
