Not sure what exactly is going on. I have a new install of CachyOS, 565.77 Nvidia driver. I have 3 displays. Center display is hooked into the Nvidia RTX 3050 6GB Desktop card, outer displays are hooked into the onboard UHD 630. I have tried both displayport ports on the 3050 and both are doing this:
Both monitors hooked to the UHD 630 work fine.
Please try the closed modules
sudo pacman -S linux-cachyos-nvidia
I will definitely try this when I can, but I’ve hit another issue now. I tried installing Bazzite Nvidia to see if I had the same problem there (I did) - and a command I found there shows that the Nvidia GPU was not being used at all despite being set to “hybrid”. Decided to reinstall cachyOS at that point, but now I can’t get cachy to boot into the live USB anymore to install, it gives me a blank screen after loading similar to this post: 7900 XTX can't boot into liveUSB or distro
I thought maybe it was because I tried bypassing the iGPU by plugging all monitors into the 3050, but plugging one back into the UHD 630 onboard gives a similar result (though with no _ now, and the 2 monitors that are on the Nvidia card show nothing at all so they turn themselves off), where the _ shows on all 3 monitors at the freeze with all 3 plugged into the 3050.
Going to try the live USB using the closed Nvidia driver this time and see where that gets me.
Okay, that worked. I’m back in CachyOS now - same issues as before, though I don’t know if using the nvidia closed option on the live installer means I have nvidia closed drivers on the actual install or not. I can see that like Bazzite, it shows off for my 3050 when I use the nvidia-smi command:
I’ll add that I don’t think I need the iGPU - should I try disabling it in BIOS to see what happens? Or is there another way to force CachyOS to ignore it?
same issue, maybe a little worse actually, after this:
sudo pacman -S linux-cachyos-nvidia
happen to know the command to go back to open drivers? I think the problem is probably related to the 3050 showing as Off with nvdia-smi?
Thanks!
sudo pacman -S linux-cachyos-nvidia-open
Yeah sure, but you need to plug in the monitor to the NVIDIA GPU first.
Success! I couldn’t find anything to disable the UHD 630, but there was an option to choose which card is the default controller when there are multiple. I switched it to Nvidia from Auto. Works great on both open and closed drivers now. Thanks!! Just gotta get bluetooth sorted now and I’m off to the races.
