Subject: xfree86: Remove broken RANDR disabling logic (v4)
Patch-mainline: Upstream
References: bnc#1068961
Signed-off-by: Michal Srb <msrb@suse.com>
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.
v2: Also remove a now entirely pointless log message, telling you to
ignore a line we will no longer print.
v3: Explain the fallback path in InitOutput. (Keith Packard)
v4: Check whether the RANDR private key is initialized before trying to
use it to look up the screen private.

Patch-mainline: To be upstreamed
Author: Michal Srb <msrb@suse.com>
Subject: randr: Do not crash if slave screen does not have provider.
References: bnc#1068961
All GPU screens are attached as unbound GPUs to master, even if they have no
capabilities or the provider field is null. Handle that case in RRTellChanged.
---
This prevents crash in setups with for example two qxl devices, or fbdev and
qxl device. I am not sure if it is a proper fix and not just papering over a
bug somewhere else, but there are more places that test whether the provider
is set, so maybe it is correct way.
I would think that if a slave screen does not have provider, there is no reason
for it to become an unbound GPU in master's slave_list. Similarly if master has
no provider, then having anything in slave_list is useless. But it seems the
AttachUnboundGPU and the rest of the code handling screen to GPU screen
attachments does not know about randr's privates, so it can not check whether
provider is there.
