I wish I could have gotten a screen scrape. Some error happened during software update after fresh install of CachyOS on new AMD 6-core. The really befuddling thing is I don’t even see 580 listed in package installer. As a result of this Einstein (sp?) will not work under BOINC and only one monitor will work. Not normally an Arch user, I was hoping to go into package install and “force re-install” like we can with other distros. Not saying it would work, but I could scrape the error.
Do the new “open” drivers allow BOINC to use CUDA? I have a dozen or so extra video cards that will run two monitors just fine. Only reason I have this one is Nvidia uncerimoniously dropped support for all of them. Open drivers for those don’t let BOINC use CUDA. Not a gamer. I write books and develop embedded systems, mostly medical devices. I can get by with an ancient Lenovo dual display port card but when machines aren’t in use I want BOINC to find cures for things.
While there are issues building that driver, I think I need to pursue a firmware update with the card vendor. When I booted Ubuntu 24.04 and a few other “live” thumb drives, they all only found one monitor. All three ports do work, one at a time. I just cannot get two to work. Gotta be some diagnostics or something I can get from MSI.
This is un-tested by me, But CUDA can work with the NVIDIA open-source driver (nvidia-open) on Arch Linux.
The nvidia-open driver provides the kernel components of the GPU stack, while the userspace components, including CUDA libraries, compilers, and other tools, remain proprietary and are separate from the open-source driver.
Therefore, installing CUDA alongside the nvidia-open driver is feasible and does not require the proprietary nvidia driver.
Please ensure the following packages are installed:
nvidia-open for the open-source kernel driver
nvidia-utils for userspace utilities
cuda for the CUDA toolkit
nvcc --version

I’m not sure how well it works so you’ll have to check it out.
This warning occurs because the consolefont hook is enabled in the mkinitcpio configuration but no specific font is set in the configuration file. Nothing to worry about.
One monitor suggests a hardware or as you pointed out firmware issue. (Cable, or Port)
Well, I have to re-install. Machine will no longer boot. Once it starts loading the graphics (judging by the screen) it crashes to recovery mode. Didn’t know about the 3 packages that were needed.
Is there a link to what video cards nvidia-open supports accessing the CUDA on? I have some older ZOTAC cards with 384 CUDA core that used to reliably run BOINC, then Nvidia kicked all previously paying customers to the curb. Got some Quadro and K2000 cards too. All worked well until a couple of years ago when they were abandoned.
Has to be firmware, OR, despite no documentation stating it and all of the online testimony as to never needing to plug in the 4-pin MOBO plug, this card needs the extra juice from the MOBO.
Individually all 3 ports work. Just cannot make two work at the same time. Going to open support ticket with MSI as the user forum just has a bunch of people reading my post without any suggestions or “me to” comments.
Since I have to wipe and re-install, will try LMDE 7 (latest Mint based on Debian instead of Ubuntu because they and many others believe Ubuntu is about to go bye-bye. Appears Fuchsia will be their forward direction pretty soon.)
As always, I will report back. Just busy with corn harvest and land tillage for next few days.
seems CachyOS dropped closed Nvidia Drivers Support when the dkms not sucessfuly builds after a Kernel Upgrade. You can check this by execucuting pacman -U nvidia-dkms-xyz in a Terminal. The exact Packaga Names you find with “ls /var/cache/pacman/pkg” - there should be located 3 Packages: nvidia-utils, lib32-nvidia, nvidia-dkms
Just to round it out, this wasn’t a driver problem. You can read about the saga here. Admittedly 580 didn’t work with Cachy when I tired this, but the problems were:
I bought a video card that didn’t have only Display Port on it just because it was on sale.
Video cables only work in one direction. Something I knew then promptly forgot because I only bought Display Port cards.
When I tested I was testing each port directly with a monitor one at a time with same connection on both ends. My primary desk has a Display Port based KVM because multi-tasking means multiple machines. That’s where the wheels came off the cart.
Now I remember why I only buy Display Port computers and video cards . . . until I forgot and bought this one.
