Xorg fails to start with 4 monitors (nvidia)

English Hardware
1

Hi,

I tried to upgrade from Leap 42.3 to 15.2 (new install).

I can get two monitors working. X seems to crash when I enable all 4 monitors with the same conf as was used in 42.3.

Graphics cards:
02:00.0 VGA compatible controller: NVIDIA Corporation GF114 [GeForce GTX 560 Ti] (rev a1) (prog-if 00 [VGA controller])
03:00.0 VGA compatible controller: NVIDIA Corporation GF114 [GeForce GTX 560 Ti] (rev a1) (prog-if 00 [VGA controller])

I have two 1920x1200 DVI monitors on each graphics card.

The Xorg logfile looks OK just almost until the end:

Are you referring to a configuration file? If so, please share that information.

Some more detailed information about your graphics card and drivers in use…

My preliminary finding with two old NVidia cards and the default Modesetting DDX is that Xorg does not find any outputs on the second card. Using instead the Nouveau DDX all four displays work, but I haven’t yet tested configuring their positions. It’s Easter today, so it will be some time yet before I can spend more time on this.

Thanks for your reply!

Here is my working /etc/X11/xorg.conf.d/20-nvidia.conf from Leap 42.3:

There’s not enough context in that log snippet to suggest to me what lead to the backtrace.

My post #3 should be disregarded. I didn’t spend enough time on the issues before writing, and TW behavior isn’t really applicable anyway.

xorg.con* files generated by nvidia-settings are intended only for use with NVidia’s own proprietary drivers. They usually include elements not applicable to FOSS drivers. Nvidia-settings’ xorg.conf* should be renamed to something not ending in .conf, or removed entirely, for FOSS drivers to do their job competently in expected fashion. FOSS graphics drivers virtually always work automagically, unusually needing any configuration in /etc/X11/ anywhere. Xinerama, as you have configured, and is off by default, would be one of the exceptions.

On upgrade to 15.2 from something older, NVidia’s drivers should be removed prior to the upgrade, and reinstalled, if necessary, only after the upgrade is otherwise successful. A successful removal usually requires following exactly the removal instructions that were supposed to be, and may in fact have been, provided with the installed proprietary drivers.

I found a motherboard here that works with 2 old NVidia PCIe cards. Whether using the Modesetting DDX or the Nouveau DDX, Plasma is using all 4 displays in 15.2. Using Modesetting DDX:

I conclude your problem must be either:

  1. remnants of NVidia proprietary drivers have survived the upgrade, or
  2. NVidia proprietary drivers for 15.2’s kernel are improperly installed, or
  3. Your NVidia cards are not supported by NVidia’s proprietary drivers in 15.2, or
  4. Some other problem specific to use of proprietary NVidia drivers, or
  5. there is a problem with your display manager (SDDM or LightDM, which might be solved by switching to the other of the two, or some other), or
  6. Your quad Xorg “screens” have a problem that a single Xorg “screen” as I used does not have.[1]

Note I have used systemsettings5 > Startup & Shutdown > Background Services to disable KScreen2, and use an xrandr script to position the outputs instead. Arandr can be used to configure such a script, or it can be done as I have, manually. This configuration method may be automatically applied regardless of Xorg session type.

[1] I tried using an adapted version of your 20-nvidia.conf, but need sleep before further proceeding further…

Hi
The G04 rpms should work? The other option is to try the hard way…

I would have thought the Desktop takes care of any configuration, I’ve not created an xorg file in a long time… I use the GNOME DE it takes care of any monitor configuration and layout (monitors.xml).

@OP, have you created a test user and logged in as the test user, do things start to function?

I did a fresh install of 15.2 on a new SSD so I would be surprised if something old could jump on it except for my old 20-nvidia.conf that i tried to get it working as before. I include the full Xorg.0.log in my next post (size limit reached) I’ll play with your suggestions later when i can boot into the new install (this is my main workhorse machine).

I conclude your problem must be either:

  1. remnants of NVidia proprietary drivers have survived the upgrade, or Don’t think so
  2. NVidia proprietary drivers for 15.2’s kernel are improperly installed, or Took Zypper commands from SDB, 2 monitors working
  3. Your NVidia cards are not supported by NVidia’s proprietary drivers in 15.2, or 2 monitors working fine
  4. Some other problem specific to use of proprietary NVidia drivers, or Could be. it has always been a pain in the arse
  5. there is a problem with your display manager (SDDM or LightDM, which might be solved by switching to the other of the two, or some other), or I thought it would be using kdm? how can i check?
  6. Your quad Xorg “screens” have a problem that a single Xorg “screen” as I used does not have.[1] As long as i can get a workspace of all 4 displays side by side I don’t care how to achieve it :wink:

Note I have used systemsettings5 > Startup & Shutdown > Background Services to disable KScreen2, and use an xrandr script to position the outputs instead. Arandr can be used to configure such a script, or it can be done as I have, manually. This configuration method may be automatically applied regardless of Xorg session type.

[1] I tried using an adapted version of your 20-nvidia.conf, but need sleep before further proceeding further…

I probably need some help doing that as I am not deep enough into the X topic to even know the precise meaning of all the acronyms used in your post. I did try nuveau and vesa-fb configurations both with more or less catastrophic outcomes. Seems I have chosen a very rare hardware configuration but I could always somehow get it to work up until Suse 42.3.

Yes they do work, but only for two displays on 1 GPU. I haven’t found a way to get the other two displays on the second GPU enabled. The nvidia applet can handle them just fine but the only option it offers is writing an xorg.conf file.

@OP, have you created a test user and logged in as the test user, do things start to function?

I don’t fully understand this instruction. I get automatically logged in as the user I created during installation. Should I create another user?

11

Hi
Yes, a test user to see if the issue duplicates. Is there not some desktop tool in the desktop environment to enable the cards/displays?

What does the output from the following show in both current user and test user?


xrandr --listproviders 
xrandr --listmonitors
xrandr --listactivemonitors
12

Thanks, Malcolm.

I created a user “test” and ran all commands for both users. Results are 100% identical for both users.


xrandr --listproviders 

Providers: number : 1
Provider 0: id: 0x279; cap: 0x1 (Source Output); crtcs: 2; outputs: 5; associated providers: 0; name: NVIDIA-0

    output DVI-I-1
    output DVI-I-2
    output HDMI-0
    output DVI-I-3

xrandr --listmonitors

There is a KDE applet called “System Settings->Display Configuration”. It shows only two displays. Nothing to enable there.

13

Hi
So if you move your xorg.conf file so there is no nvidia configs around, you have nouveau blacklisted and as an additional check rebuild initrd with mkinitrd and reboot, what happens?

If you get to a tty, then just copy your xorg.conf file back.

14
  • removed my 20-nvidia.conf
  • Nuveau was already blacklisted in /etc/modprobe.d/nvidia-default.conf
  • ran mkinitrd
  • rebooted
  • got KDE on 2 displays
  • restored my 20-nvidia.conf
  • rebooted

Result: X crashes with the same messages.

15

Hi
Can you logout and select iceWM and login as your test user, does it see all displays?

Can you also show the output from;


/sbin/lspci -nnk | egrep -A3 "VGA|Display|3D"
/sbin/modinfo nvidia | grep "filename:"
16

Thanks, Malcolm.

  • logged in as user test (iceWM)
  • sees only 2 displays

/sbin/lspci -nnk | egrep -A3 "VGA|Display|3D"

Hi
I’m really not sure if the weak-updates location is the issue. I’d be tempted to install the hard way and see if that helps…

https://en.opensuse.org/SDB:NVIDIA_the_hard_way

18

Thanks, Malcolm.
I don’t think that the location is an issue because it seems to be the standard location where it gets installed. My working 42.3 installation returns

/sbin/modinfo nvidia | grep "filename:"
filename:       /lib/modules/4.4.180-102-default/weak-updates/updates/nvidia.ko
19

Hi
Well the only way to confirm any further is to switch to nouveau or modesetting driver… one thought if you boot with the nomodeset option in grub, does that make a difference?

Here on Tumbleweed, no issues with multiple cards/displays but again, no X configuration at all for the nvidia card… just plug and play with my quick tests as don’t use them except for offload.

I have a feeling that xrandr doesn’t like exactly identical port names.

Are your displays on ports with potentially ambiguous names?

Do you have multiple nvidia GPU’s installed? Are these cards identical or different models?
