What I’ve done so far on this attempt

Fresh manjaro install with free drivers. All monitors working.
sudo pacman -Syyu - rebooted
Did the auto install proprietary driver – rebooted
Benq monitor (primary) on the 2080 card comes up. Others do not.
Tried activating other monitors through Display Configuration utility, nothing happens when I apply changes and when I reopen it changes were not saved.
Tried activating other monitors through nvidia-settings utility ran under sudo. Saved X configuration to file in my home directory and copy-paste replaced the contents of /etc/X11/xorg.conf.d/0-mhwd.conf with it… I noticed that file was symlinked to /etc/X11/mhwd.d/nvidia.conf so I was hoping that would do the trick. No dice.

Contents of that file:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 470.57.02

Oh I had Xinerama turned off cause I thought it was for spanning a single “screen” over multiple displays. I’ll look into it. ty

NotGovernor · 25 July 2021 23:45

No change with the above – still just the main monitor on.

Question: Whats the best way to restart X without restarting the whole computer after I’ve made a conf change? I’ve been CTRL-ALT F#'ing to a terminal pgrep’ing the Xorg and killing it… But I’m not sure that reloads the config.

Question #2: How do I know it’s looking at this /etc/X11/xorg.conf.d/0-mhwd.conf symlinked to /etc/X11/mhwd.d/nvidia.conf ? Changes I’m making arent having any affect so this seems like something to check.

NotGovernor · 26 July 2021 00:23

I’m adding a $50 reward if someone wants to screen share with me to:

Get my multihead working.
Teach me about this pluming and whats going wrong.

Contact me on Telegram @NotGovernor if interested. Thanks! <3

chris_jung · 26 July 2021 07:57

Use Manjaro Settings Application, check your used Kernel. If it’s linux513, install 512, uninstall 513. Reboot.

pux · 26 July 2021 14:04

Interesting that it works with free drivers

Maybe it’s worth a try to update your bios since it is pretty old.

openminded · 26 July 2021 14:58

Ctrl + Alt + Backspace should restart X server but I’m not sure if new settings would be picked without reboot though…
As for the other question, to answer that we need to see what else is there in /etc/X11/xorg.conf.d/ exactly.

NotGovernor · 28 July 2021 20:33

It was 5.10.53-1 LTS. But I just tried both 512 and 513 just to see if it resolved it. Unfortunately it didnt.

Going to try the 514 rc3 experimental right now as well just to see. I’m running out of ideas.

EDIT: It didnt.

philm · 28 July 2021 20:46

Did you ever tried to swap the monitors on the cards. For me it looks like that only the primary card gives out some picture signal.

NotGovernor · 28 July 2021 21:01

Thanks for the recommendation. Done.

No change unfortunately.

NotGovernor · 28 July 2021 21:04

The CTRL+ALT+Backspace doesnt appear to do anything for me.

Heres my listing:

Yes, that appears to be the case – I’m trying to get the second card working with the monitors plugged into it.

openminded · 29 July 2021 03:00

OK, so what does your /etc/X11/mhwd.d/nvidia.conf looks like at the moment?

NotGovernor · 29 July 2021 18:07

I’ve tried about 20 different configs at this point… And strangely nothing I’ve done to this file has had any effect whatsoever.

But here’s the current one:

As far as I can see “it should just work” because:

Added support for PRIME Display Offload where both the display offload source and display offload sink are driven by the NVIDIA X Driver.

is mentioned in the 472.42.01 changelog.

Have you tried getting rid of all video related Xorg configuration files, rebooting, and just running

xrandr --setprovideroutputsource NVIDIA-G0 NVIDIA-0

?

Thank you for the suggestion –

Done – deleted all the related files and the symlink and rebooted. Here’s my listing now:

After the reboot I logged in – still just the main monitor working. Opened terminal and executed your command. No change unfortunately.

What does xrandr --listproviders show?

NotGovernor · 30 July 2021 23:56

Same as in OP.

xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x1b8 cap: 0x1, Source Output crtcs: 4 outputs: 8 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x377 cap: 0x2, Sink Output crtcs: 4 outputs: 7 associated providers: 1 name:NVIDIA-G0

Question – as a compromise – Can I run the nvidia drivers on my main card/monitor and the free drivers that work on the 2nd card and its monitors? Is that a thing that can be configured?
