[SOLVED] cant get extended desktop with intel + radeon cards on xorg

sinoseque · 2016-01-27 20:53:23

Hi guys,

i am not able to get what i want... i have 2 graphic cards and i want to get 1 extended desktop with 2 screens, i have tried ... without xorg.conf, and ... with some options in a xorg.conf but i have failed

my lspi | grep VGA output:

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii PRO [Radeon R9 290]

if i start xorg without any xorg.conf file and i execute xrandr -q i get:

Screen 0: minimum 8 x 8, current 1280 x 1024, maximum 32767 x 32767
HDMI2 disconnected (normal left inverted right x axis y axis)
HDMI3 disconnected (normal left inverted right x axis y axis)
VGA1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm
1280x1024 60.02*
1152x864 75.00
1024x768 75.08 70.07 60.00
800x600 72.19 75.00 60.32 56.25
640x480 75.00 72.81 60.00
720x400 70.08
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

and xrandr --listproviders output:

Providers: number : 2
Provider 0: id: 0x96 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 4 associated providers: 0 name:Intel
Provider 1: id: 0x59 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 6 outputs: 4 associated providers: 0 name:radeon

it shows 2 cards, but only the first one is working

if i use this xorg.conf i get 2 screens up, but it works as separate desktops, i cant drag windows between them:

Section "ServerLayout"
Identifier "Main Layout"
Screen 0 "screen0"
Screen 1 "screen1" RightOf "Screen0"
EndSection
Section "Device"
Identifier "radeon"
Driver "radeon"
BusID "PCI:1:0:0"
EndSection
Section "Device"
Identifier "intel"
Driver "intel"
BusID "PCI:0:2:0"
EndSection
Section "Monitor"
Identifier "mintel"
Option "PreferredMode" "1280x1024"
Option "Position" "1920 0"
Option "Primary" "true"
EndSection
Section "Monitor"
Identifier "mradeon"
Option "PreferredMode" "1920x1080"
Option "Position" "0 0"
EndSection
Section "Screen"
Identifier "screen0"
Device "radeon"
Monitor "mradeon"
EndSection
Section "Screen"
Identifier "screen1"
Device "intel"
Monitor "mintel"
EndSection

and with this xorg.conf if i execute xrandr -q in the screen of radeon device i get:

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)

1920x1080 60.00*+
1680x1050 59.88
1280x1024 75.02 60.02
1440x900 59.90
1280x960 60.00
1280x800 59.91
1152x864 75.00
1280x720 60.00

832x624 74.55
800x600 72.19 75.00 60.32 56.25
640x480 75.00 66.67 60.00
720x400 70.08

and xrandr --listproviders shows:

Providers: number : 1
Provider 0: id: 0x59 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 6 outputs: 4 associated providers: 0 name:radeon

as u can imagin, if i do same in the other screen, i get the output of intel device:

xrandr -q
Screen 1: minimum 8 x 8, current 3200 x 1024, maximum 32767 x 32767
HDMI2 disconnected (normal left inverted right x axis y axis)
HDMI3 disconnected (normal left inverted right x axis y axis)
VGA1 connected primary 1280x1024+1920+0 (normal left inverted right x axis y axis) 376mm x 301mm
1280x1024 60.02*+
1152x864 75.00
1024x768 75.08 70.07 60.00
800x600 72.19 75.00 60.32 56.25
640x480 75.00 72.81 60.00
720x400 70.08
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x96 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 4 associated providers: 0 name:Intel

... i dont know what to do to solve this, driver version and xorg-server are:

Nombre : xf86-video-ati
Versión : 1:7.6.1-1
Nombre : xf86-video-intel
Versión : 1:2.99.917+519+g8229390-1
Nombre : xorg-server
Versión : 1.18.0-4

I would be very grateful if someone can give me some help.

thx in advance.

IT WORKS with:

xrandr --setprovideroutputsource radeon Intel
xrandr --output DVI-1-1 --auto --left-of VGA1

Welcome to Arch. Creating two screens in xorg.conf is not the way to go, because as you say, they will not be connected. Another thread suggests the command "xrandr --setprovideroutputsource 0 1" but I haven't tried this.

sinoseque · 2016-01-27 22:10:34

thx ConnorBehan, i have tried it, but when i do it, nothing happens :_(

sinoseque · 2016-01-27 22:40:37

sorry, something happens... X crashes!!!!

sinoseque · 2016-01-28 00:06:09

I have seen these lines in xorg.log when i try "xrandr --setprovideroutputsource 0 1"

[ 30.678] (II) Loading sub module "fbdevhw"

i have tried start X as root but same problem

sinoseque · 2016-01-28 00:16:05

i have tried with Xwrapper.config

allowed_users=anybody
needs_root_rights=yes

but still doesn't work.

Lone_Wolf · 2016-01-28 09:53:24

[    30.678] (WW) VGA arbiter: cannot open kernel arbiter, no multi-card support

that message can usually be ignored.

You'll have to use xrandr to setup the screens also, Check the PRIME wiki page, section "Reverse Prime"

sinoseque · 2016-01-28 10:38:39

Thx Lone_wolf i though prime was about hybrid cards. But it seems what u say. I have to test it. Thx again.

sinoseque · 2016-01-28 13:33:35

THX BOTH ConnorBehan and Lone_Wolf!!!!

IT WORKS with:

xrandr --setprovideroutputsource radeon Intel
xrandr --output DVI-1-1 --auto --left-of VGA1

Glad it works now.

PRIME indeed has to do with hybrid graphics, but every system with an integrated AND a discrete videocard IS a hybrid graphics system.
