Workstation, not server, so I need one gpu for displays, the rest for compute.
6.1.55-1-MANJARO (Arch) system, either Xorg or Wayland
I want to use an old Quadro nvs450 but it needs old 340xx driver, while the other gpu(s) need new drivers.
I could perhaps also use a generic driver like modesetting, but I can’t get Xorg to load up modesetting for the quadro.
How can this be done? Can I somehow have several nvidia drivers installed without conflict? Do I need to use some generic driver? How do I set that up?
This only works with a lot of hassle. First of all, it absolutely doesn’t work by loading two different nvidia proprietary driver versions. Then, the 340 driver is out of support for years now, I doubt you wil find a working one. What works to some degree is using the nouveau driver+nvidia driver. In short, blacklist nouveau, let the nvidia driver load, possibly using the NVreg_ExcludedGpus to not try the old gpu, then manually loading the nouveau driver to override the blacklist, then starting X/wayland. Or use no driver and deal with simpledrm/framebuffer device without accel. Or buy a simple, modern graphics card.
you make good points except I just looked up newer graphics cards and none are as good as this old one: 4xdisplayport, fanless, compact, low energy, $ = free since I own it. If you know of one that would be great, 2x ports is okay.
I did try nouveau and it wouldn’t display unfortunately.
Is there are guide to use it with no driver, curious about that.
UPDATE: okay pcpartpicker shows cards with multi displayport and even fanless options.So there’s that. It would be good to have more control over a system and the drivers though
