Any way to run 2 monitors with linux70 and NVIDIA GeForce GT 1030?

I have a compact PC that has an NVIDIA GeForce GT 1030 discrete graphics card (according to the KDE system info tool). Since the last few updates it has needed the nvidia-575 modules which are not available for the 7.0 kernel.

I operate it with 2 monitors, one connected to the HDMI output and the other to the DVI

When I try to run it with the Nouveau drivers, only the HDMI output is active, and the system info tool says the graphics cards is “llvmpipe”. (Both on 6.18 and 7.0). I do have the nvidia firmware installed (initially I got a missing firmware message when updating grub, but that is fixed).

Is there any way to get dual monitor without remaining on 6.18 in perpetuity? In particular:

  • Probably best is to find a way to configure nouveau to drive both monitors – it is quite possible I’ve missed some config option, but the KDE system settings doesn’t show the existence of another monitor.
  • Alternatively would using the dkms modules to build for 7.0 work? It’s ages since I used dkms modules, so a pointer to a guide would be appreciated.

The 580 series is the latest for that card, 575 is long EOL.

Why then did nvidia-driver-assistant say I needed the 575 drivers?

Will try using 580 and report what happens in the next few days?

nvidia-driver-assistant is a bit behind, unfortunately.

EDIT: As of nvidia-driver-assistant 0.23.48.01-7, it will recommend the 580xx series.

However, MHWD has been updated. You can auto install the proprietary driver with Manjaro Settings Manager or via the CLI tool.

If this works for your needs, you can tunnel video through USB with version 3 and up.

Does the PC have USB 3.X or better?

You can see, sort of, with:

lsusb -t

Look for the highest numbers in M (Mbps).

On mine, I have a couple ports like:

/:  Bus 006.Port 001: Dev 001, Class=root_hub, Driver=xhci_hcd/4p, 10000M

Even on my older Xen 3 system, I can do 10000M (Mbps). But only through two of my ports.

If you have USB 4/Thunderbolt, I can’t help you here. I haven’t had the pleasure yet.

sudo boltctl list

I think you start here?

An inxi -zv8 would have helped some too.

With my laptops where one output is the only option, I just buy an extra video port via USB. These are generally reasonably priced devices.

They are incorrectly advertised as things like:

  • USB-C to HDMI adapter
  • USB 3 video cable
  • USB Type-C display adapter

We most likely just want ones that support DisplayPort Alt Mode. But you won’t find that in the description usually. Cheap ones should be under €25. (And many are a USB hub additionally.)

Getting the usual advertised 2160p @ 60Hz may be tough through some hardware, but 1080p @ 60Hz (or somewhere in the middle) I found to be always snappy.

And whether it’s USB 3, or 4/Thunderbolt, they both use a driver from the official kernel for video, so no proprietary modules.
