Hello, I chose to revert to Linux (Solus: Mate) because the game support has improved significantly. I have two GPUs: one is a GTX 580 ASUS 1.5GB GDDR5 (main GPU), and the other is a GT 730 EVGA 1GB GDDR5. On Windows, the second GPU worked and displayed output, but with Linux it doesn’t seem to function. Can anyone confirm if it’s possible to use a second GPU and if so, how would I set it up? PC specs: CPU FX 8150, RAM 12GB DDR3 1600MHz, Sound Card ASUS GDX.

I wonder why that second GPU exists at all. Besides, it's the pleasure of Linux and its driver capabilities handling things. If fixing this didn't take days, I'd be right there on Linux with you.

Well, the situation turned into a bit of a tale. I owned a spare GPU called the GT 730, while my main one was the GTX 580 which only came with a few ports—just one HDMI, two DVI-I, and one Display Port. I didn’t have the necessary cables, but I had an extra GPU. I connected it to my PC and the issue disappeared until I switched to Linux. I assumed Linux would handle multiple GPUs well, since it leads in servers. However, my monitors didn’t support DisplayPort or DVI-I, so even with an adapter from DVI-I to VGA, Linux couldn’t display the right resolution. I tried using xrandr to manually adjust settings, but kept getting errors. It’s frustrating; I feel like the only options are buying another GPU or reverting to Windows. I’ve looked everywhere online for a fix and found some solutions. I also experimented with different distros—Ubuntu 16.04.3, Antergos GNOME, Solus Mate—but it seemed the problem might lie in the distribution itself.

previously they kept using VGA in the server environment, and only heavy GPUs were used for custom rendering tasks. Additionally, while NVIDIA's Linux drivers perform reasonably well in terms of speed, they come with a limited feature set. I’m sure it can be made to function, but currently I’ve disabled the dedicated GPU on my home server since Intel graphics aren’t as much of an issue, and I don’t need any graphics work.
