 Posted: Mon May 20, 2019 6:47 pm Post subject: 2 gpu + 2 monitors not working |
 |
|
So I have 2 gpu in my PC (Intel onboard and Nvidia GeForce GT 710) and 2 monitors and can't get them working at the same time.
In BIOS, I set the onboard gpu as the default.
In my make.conf, I got:
| Code: |
VIDEO_CARDS="intel nouveau"
|
My /etc/X11/xorg.conf.d/40monitor.conf looks like:
| Code: |
Section "Device"
Identifier "Intel"
Driver "intel"
EndSection
Section "Device"
Identifier "Nvidia"
Driver "nouveau"
EndSection
Section "Monitor"
Identifier "HDMI0"
EndSection
Section "Monitor"
Identifier "HDMI1"
Option "RightOf" "HDMI0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Intel"
Monitor "Monitor0"
EndSection
Section "Screen"
Identifier "Screen1"
Device "Nvidia"
Monitor "HDMI1"
EndSection
|
But xrandr --query says HDM1 is disconnected:
| Code: |
Screen 0: minimum 8 x 8, current 2560 x 1440, maximum 32767 x 32767
HDMI1 disconnected primary (normal left inverted right x axis y axis)
HDMI2 connected 2560x1440+0+0 (normal left inverted right x axis y axis) 550mm x 310mm
2560x1440 59.95*+
2048x1080 60.00 24.00
1920x1080 60.00 50.00 59.94
1920x1080i 60.00 50.00 59.94
1600x1200 60.00
1280x1024 75.02 60.02
1152x864 75.00
1280x720 60.00 50.00 59.94
1024x768 75.03 60.00
800x600 75.00 60.32
720x576 50.00
720x576i 50.00
720x480 60.00 59.94
720x480i 60.00 59.94
640x480 75.00 60.00 59.94
720x400 70.08
VGA1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
|
And even in arand I cant select HDMI1.
On the second monitor, I get "no input source" (and I did set input to HDMI).
What did I mess up?
Xorg.0.log
kernel config
dmesg

vlynd,
| Code: | Section "Device"
Identifier "Nvidia"
Driver "nvidia"
EndSection |
To be consistent with | Code: | | VIDEO_CARDS="intel nouveau" |
The Driver in that Device section should be "nouveau". "nvidia" means the evil binary blob.

Thanks. I edited the file /etc/X11/xorg.conf.d/40monitor.conf but the problem did not disappear.
Also, I edited my original post with nouvea as driver. |

vlynd,
Make friends with wgetpaste.
Use it to put dmesg, /var/log/Xorg.0.log and your kernel .config onto a patebin site.
Post the three links so we can find them.

vlynd,
dmesg shows i915, nouveau and nvidia-drivers loading.
nouveau and nvidia-drivers are fighting over your nVidia card.

nvidia drivers lost.
From Xorg.0.log
| Code: | [ 8.389] (II) intel: Driver for Intel(R) Integrated Graphics Chipsets
[ 8.389] (II) NOUVEAU driver for NVIDIA chipset families : |
both loaded.
The Intel card says
| Code: |
[ 8.438] (II) intel(0): EDID for output HDMI2
[ 8.438] (II) intel(0): Manufacturer: DEL Model: 40e1 Serial#: 875706188

[ 8.442] (EE) intel(0): Cannot position output HDMI1 relative to unknown output HDMI0
|
The nouveau driver says
| Code: | [ 8.609] (II) NOUVEAU(G0): EDID for output HDMI-1-3
[ 8.609] (II) NOUVEAU(G0): Manufacturer: ACR Model: 2607 Serial#: 5024
[ 8.609] (II) NOUVEAU(G0): Year: 2018 Week: 39
..
[ 8.621] (II) NOUVEAU(G0): Virtual size is 1024x768 (pitch 0)
[ 8.621] (**) NOUVEAU(G0): Mode "2560x1440": 312.2 MHz (scaled from 0.0 MHz), 89.5 kHz, 60.0 Hz
|
So Xorg sees both displays. That much works. Having nvidia-drivers installed is just untidy.
Remove it when you got the chance.
| Code: | | [ 8.442] (EE) intel(0): Cannot position output HDMI1 relative to unknown output HDMI0 |
suggests that Xorg cannot understand your ServerLayout section.
Your kernel config must be OK. Both Intel an Nouveau are working correctly.
Back to dmesg
| Code: | | [ 0.074934] [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x22 (or later) |
Updatingyour microcode would be a good thing.
| Code: | | [ 1.981978] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 |
Thats only needed for WiFi.
Ignore the message if you don't have WiFi.

NeddySeagoon,
thanks for your time.
I updated my BIOS and installed the sys-firmware/intel-microcode package but the message still exists in dmesg:
| Code: |
[ 0.074878] [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x22 (or later)
|
I completely removed the nvidia blob drivers.
But still I only get one monitor working.
full dmesg
/var/log/Xorg.0.log
/etc/X11/xorg.conf.d/40monitor.conf
Edit:
This is my Xorg.0.log when I comment everything in 40monitor.conf out. |

vlynd,
The easy one first.
| Code: | [ 1.948932] microcode: sig=0x306c3, pf=0x2, revision=0x19
[ 1.950069] microcode: Microcode Update Driver: v2.2. |
You need a newer microcode. The kernel knows that 0x22 is out there.
Back to your dual monitors.
The xorg.config is stuck together with all the fragments in /etc/X11/xorg.conf.d/ by following the and
It can all be in a single file. is worth a read.
Somewhere, you need a | Code: | | Section "ServerLayout" |
that describes how to put it all together.
In particular, You need to describe how your multiple displays are arranged with respect to one another.
The Section "ServerLayout" is described almost at the end of the man page.

thanks again.
Fixed the microcode stuff:
| Code: |

|
Added a ServerLayout section to my 40monitor.conf file, but still,

Second monitor is on and connected. 
Edit: what is the preferred image upload service around here?
Edit 2: Ah, I think I found something:

VGA1 is taking the Monitor from HDMI1.

vlynd,
The nVidia card found this display.
| Code: | [ 468.287] (II) NOUVEAU(G0): EDID for output HDMI-1-3
[ 468.287] (II) NOUVEAU(G0): Manufacturer: ACR Model: 2607 Serial#: 5024
[ 468.287] (II) NOUVEAU(G0): Year: 2018 Week: 39 |
but
| Code: | [ 468.299] (II) NOUVEAU(G0): Virtual size is 1024x768 (pitch 0)
[ 468.299] (**) NOUVEAU(G0): Mode "2560x1440": 312.2 MHz (scaled from 0.0 MHz), 89.5 kHz, 60.0 Hz
[ 468.299] (II) NOUVEAU(G0): Modeline "2560x1440"x60.0 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync (89.5 kHz)
[ 468.299] (==) NOUVEAU(G0): DPI set to (96, 96) |
Where did it get get that modeline?
Its not in the EDID data from the display and will probably cause the displaf to output Video Out of Range.
What else do you have in /etc/X11/xorg.conf.d/ ?
| Code: | | cat /etc/X11/xorg.conf.d/* |
would be good.
The Intel driver is not as talkative
| Code: | [ 468.121] (II) intel(0): Output VGA1 using monitor section Monitor1
[ 468.121] (II) intel(0): Enabled output VGA1
...
[ 468.314] (II) intel(0): switch to mode 2560x1440@60.0 on HDMI2 using pipe 0, position (0, 0), rotation normal, reflection none
[ 468.315] (II) intel(0): Setting screen physical size to 677 x 381 |
but VGA cannot support that resolution ...
Which display work?
The one on the intel card or the one on the nvidia card?
At face value, frow that log, I would say neither.
What are the native resolutions of the two displays?
How are they actually connected to the computer video outputs?

There are just two files in /etc/X11/xorg.conf.d/ :
20opengl.conf (I did not create this):
| Code: |
Section "Files"
EndSection
|
And 40monitor.conf.
I don't know where it gets the resolution from, but that's completely wrong. The max resolution for the second monitor (connected to the Nvidia card) is 1920 x 1.200.
The native resolution for the first (connected to intel) monitor is: 2560 x 1440
Actually, I don't have anything connected to VGA. Both connectors are HDMI.
After initialising the second monitor (connected to the Nvidia card) with:
| Code: |
xrandr --setprovideroutputsource 1 0
|
Both monitors are working simultaneously. But the image on the second monitor is completely screwed up.
You can see it here: https://i.imgur.com/MjpcC5q.jpg (better photo)
(Don't know if imgur is accepted here, I could also upload it somewhere else)

vlynd,
Thats an image I have not seen for a long time.
Its what happens when the the display is given an out of range video signal and doesn't blank it.
It looks ugly but its harmless to flat panel displays. It can destroy a CRT display.
The next step is to track down where that rogue modeline comes. from.
From the log
| Code: | [ 1438.346] (II) NOUVEAU(G0): Supported detailed timing:
[ 1438.346] (II) NOUVEAU(G0): clock: 154.0 MHz Image Size: 0 x 0 mm
[ 1438.346] (II) NOUVEAU(G0): h_active: 1920 h_sync: 1968 h_sync_end 2000 h_blank_end 2080 h_border: 0
[ 1438.346] (II) NOUVEAU(G0): v_active: 1200 v_sync: 1203 v_sync_end 1209 v_blanking: 1235 v_border: 0
[ 1438.346] (II) NOUVEAU(G0): Ranges: V min: 24 V max: 120 Hz, H min: 15 H max: 100 kHz, PixClock max 175 MHz
[ 1438.346] (II) NOUVEAU(G0): Monitor name: ACER H6521ABD
[ 1438.346] (II) NOUVEAU(G0): Serial No: JQ61100L5900 |
So the display tells nouveau h_active: 1920, v_active: 1200 and that's the preferred mode.
Then at the last minute the wheel comes off with
| Code: | [ 1438.358] (**) NOUVEAU(G0): Mode "2560x1440": 312.2 MHz (scaled from 0.0 MHz), 89.5 kHz, 60.0 Hz
[ 1438.358] (II) NOUVEAU(G0): Modeline "2560x1440"x60.0 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync (89.5 kHz) |
What happens if you swap the video connectors over to the PC.
The nVidia card will make a much better job of 2560x1440 than the intel card anyway.

I'm completely re-writing this post.
So after much tinkerin around, I got both monitors to work. There's a setting in my BIOS where I can enable multihead when I pick the exteranl gpu as the default one.
But: I only get a completely distortion-free (not like in my previous linked image) without a manual xorg.conf-configuration. Even in full resolution 1920x1200.
But then (with no manual configuration) the second monitor is the default one. This is bad since the beamer is not always turned on.
So with the following configuration I get the onboard gpu to work as the default one, but the beamer image is out of range.
How do I get the image distortion-free? I tried so many variations of hz/vsync/etc and checked out the projector manual. Howevery, nothing worked, except when I dont write anything in the xorg.conf (which is a little bit ironic).
Maybe I'm stuck in the tunnel. Howevery, thanks again for your help, NeddySeagoon. |

vlynd,
You can try writing a modeline for the projector.
The best way to do that is to cheat.
Run the system so it works and look at what Xorg is using. I'll guess that its
| Code: | [ 1438.346] (II) NOUVEAU(G0): clock: 154.0 MHz Image Size: 0 x 0 mm
[ 1438.346] (II) NOUVEAU(G0): h_active: 1920 h_sync: 1968 h_sync_end 2000 h_blank_end 2080 h_border: 0
[ 1438.346] (II) NOUVEAU(G0): v_active: 1200 v_sync: 1203 v_sync_end 1209 v_blanking: 1235 v_border: 0 |
That translates to | Code: | | modeline "1920x1200@60Hz" 154 1920 1968 2000 2080 1200 1203 1209 1235 |
"1920x1200@60Hz" is the identifier I made up.
154 is the pixel clock
1920 1968 2000 2080 is the description of a line in terms of pixel counts, so a line time is 2080pixels/154MHz That's 13.506493506 microseconds.
1200 1203 1209 1235 is the description of a frame in terms of lines, so the frame time is 16680.519480519 microseconds
That's 59.95 frames per sec.
Having defined your modeline you tell Xorg to use it.
The modeline definition goes in the Section "Monitor" where it will be used. This means that its only available for this monitor.
xorg.conf also supports a Section "Modes" so you can use the modelines on any number of displays.
In the Section "Screen", that calls up the Section "Monitor" that contains the modeline, you need a
| Code: | Subsection "Display"
Depth 24
Modes "1920x1200@60Hz"
EndSubsection |
that tells Xorg to actually use the modeline.
Heres the hard bit. Some drivers will ignore the emergency manual override described above.
Most but not all in that group have an option to give you control. Its not documented in
Try it and see.

Did I mess something up with the ModeLine?
The horizontal stripes still exist.

Some drivers will ignore the emergency manual override described above.

So the second monitor works when Xorg configures itself but not when I do it?
Edit:
What I noticed: Starting X without any config is different than running "X -configure" and starting X with the resulting config.
Also, starting with that generated config also has the horizontal stripes on the second monitor.
But I couldn't find any other way to dump the current config (when starting without any config file). |

vlynd,
I apologise for my creative use of English.
The automatic set up has become so good in most situations that some video drivers ignore manual configuration settings totally.
Others need a special option, to tell them that you really want to use a manual configuration.
Yet others will use the manual configuration when its given.
I have no idea which group nouveau falls into. Hence try it and see.
Manual settings are colloquially known as "the emergency manual override" since many early flat panel displays shipped with faulty EDID data, which meant that the automatic set up operated correctly on incorrect data. The fix, providing a modeline, was known as "the emergency manual override".
I thought that had been broken for years.
Please pastebin the Xorg.0.log when it attempts to use your modeline. Your .config file looks good. I may have messed up, there may be a hint in the log.
Also provide the Xorg.0.log generated with no .config. The differences between the two may help.

NeddySeagoon,
I think it has more to do with my lack of knowledge when it comes to graphics and drivers.
With /etc/X11/xorg.conf: /var/log/Xorg.0.log.
Without /etc/X11/xorg.conf: http://dpaste.com/08N2FQF.
Another idea that I had: starting without any xorg.conf.
Then, only the second monitor is active (which is by default turned off).
Login via xdm and put
| Code: |
xrandr --setprovideroutputsource 1 0
xrandr --output HDMI2 --auto
|
in my xinitrc.

vlynd,
Did I miss this?
| Code: | | [ 84013.490] (==) Using config file: "/etc/X11/xorg.conf" |
You have been posting fragments from /etc/X11/xorg.conf.d/ up until now.
Your modeline identifier "1920x1200@60Hz" should have been listed in Xorg.0.log.
Use either /etc/X11/xorg.conf or /etc/X11/xorg.conf.d/ but not both.
Your links both point to the same paste.

NeddySeagoon,
yes, for the latest reply I was using a xorg.conf file which was generated by X -configure.
For this, I moved the directory xorg.conf.d so that only the file xorg.conf was used.
This is the logfile with xorg.conf:

This is the logfile without:

Why let you think that? user want use nouveau for whatever reasons he had. It doesn't mean nvidia drivers cannot do it too.
And users with optimus are doing it |

If you want to use multiple graphics cards from multiple vendors to drive multiple displays at the same time, then the old wisdom is no. nVidia proprietary drivers (And AMD/ATi if you want to use a very old AMD card or a former ATi card) replace much of the graphics stack and cannot be used at the same time as an AMD, ATi, Intel, or other GPU.
If you want to do this with ONLY nVidia cards, and you have two nVidia cards of a similar age so they can use the same proprietary driver version, then you might actually have an easier time getting it to work that way.

I have tried getting a system with two GPUs to output to two monitors at the same time in the past. It was hot garbage. Once I finally got it working there were severe glitches with the mouse cursor that made it unusable.
More importantly, it was far enough in the past that the rule was still you cannot combine proprietary drivers with free drivers on the same system. It just didn't work at all. This MIGHT have changed with better support for multi-GPU laptops (I vaguely remember a news article that nVidia would change the driver to replace less of the graphics stack), but this isn't necessarily the same thing because the second GPU in a laptop is usually used only for accelerating games and doesn't drive a second monitor. |
