I'm trying to set up a xinerama arrangement over two graphics cards
(Intel + Radeon), taking advantage of xrandr 1.4's features which
(I understand, perhaps mistakenly, to) support this configuration.
I'm running xorg server 1.13.4 on Gentoo. It might be useful for
you to know in addition that I'm running a barebones KDE 3.5.10
desktop on it.
If I do --listproviders, I get both cards listed:
# xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x87 cap: 0xb, Source Output, Sink Output, Sink
Offload crtcs: 3 outputs: 3 associated providers: 0 name:Intel
Provider 1: id: 0x57 cap: 0xd, Source Output, Source Offload, Sink
Offload crtcs: 6 outputs: 2 associated providers: 0 name:radeon
However no use of --setprovideroutputsource or
--setprovideroffloadsink (with arguments "0 1" or "1 0") will do
what I want. Am I completely misunderstanding this?
One monitor is connected to VGA output of integrated Intel GPU, and
the other to DVI output of Radeon (HD 7570) PCI card. I think kernel
stuff is set up properly:
# lsmod | grep radeon
radeon 858404 1
cfbfillrect 3714 2 i915,radeon
cfbimgblt 2039 2 i915,radeon
ttm 58739 1 radeon
cfbcopyarea 3350 2 i915,radeon
drm_kms_helper 26569 2 i915,radeon
fb 33637 6
i915,fbcon,drm_kms_helper,radeon,softcursor,bitblit
backlight 4248 2 video,radeon
Please document this functionality more clearly! Any help with this
will be much appreciated. I can try to end-run the problem by asking
my boss to buy me an HDMI-capable monitor, to plug into the second
port of Intel card, but I've already got the Radeon, and I'd rather
try to figure this out before throwing money at it :-) Thx.
So.... I've left this sit for a while and it doesn't look like there's
anyone here able to help.
Is there a better place to ask for help with xrandr? Have I left out
some crucial information?
I find config files easier to work with than xrandr. You might want to try.
My last dual head session with Intel and Radeon left these behind:

https://01.org/linuxgraphics/documentation/how-set-dual-head-intel-graphics-randr-1.2
Something else to consider:
KDE 4.11 has KScreen, which is supposed to provide easy management of multi
screen configuration.
