This probably was asked countless times already, but given the amount of possible combinations of all the hardware and software, this is probably not surprising.

So, I do have some experience with linux. I ssh into my ubuntu server a lot, I do many bash/terminal tricks, so can’t really call myself a newbie in Linux. However, for gaming I would use Windows for as long as I remember myself. With the release of KDE Plasma 6 and Vulkan support getting better, I was thinking about giving it a go, but I’m stuck.

When launching a game that natively supports linux (Dota 2) from Steam, pretty much nothing happens. I see in terminal that there are some errors, but archwiki states that this is normal:

Wrong ELF class

If you see this message in Steam’s console output

ERROR: ld.so: object '~/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

you can safely ignore it. It is not really any error: Steam includes both 64- and 32-bit versions of some libraries and only one version will load successfully. This “error” is displayed even when Steam (and the in-game overlay) is working perfectly.

Other than that I see no errors or anything.

I’m running Arch linux with KDE Plasma 6.0.1, with default Wayland session. My laptop is an Acer Nitro 5 with NVIDIA GPU and I guess also Intel integrated video card. Here are the details:

I have no idea honestly about which driver I have installed, but I did install nvidia package. I’m not sure if it’s being used. I also don’t know anything about Mesa. Also, this is from my Info Center:

I don’t even know what is Xwayland and why I have it installed, probably some dependency of KDE.

At this point I’m not even sure what I’m using (is it pure wayland, or x11, or some hybrid of using both), if I have correct GPU drivers (do I have correct drivers for just one of the two video cards, for both, or none at all), if my NVIDIA GPU is even working, if it’s being used to run a game or not, and if I have all necessary packages to run Vulkan.

At this point, how do I troubleshoot all of this mess?

      I might try this as a last resort, but why would I use some emulation shenanigans for running something that is native to my platform? It would be easier to just reboot into windows and run dota 2 there instead.

        I have read on more than one occasion that Wine is becoming the “Linux Gaming ABI.” It’s no longer just about Windows. With the huge variety presented by distros, Wine is simply a nice stable target that never moves.

          This is an interesting thought, but I’ll try to have it working natively first.

        I think Dota doesn’t run on proton, i had no problems running the native linux version with my laptop intel i7 + nvidia 1050ti, but it was on X11, u can probably choose that on login screen.

        What i think you need from a fresh install (i don’t remember exactly what i did at the time):

        • enable multilib
        • install nvidia package or nvidia-lts depending on which kernel you’re using, or nvidia-dkms plus headers of your kernel
        • install nvidia-settings nvidia-utils lib32-nvidia-utils nvidia-prime (never used bumblebee i just use prime-run)
        • install steam or steam-native-runtime
        • install game on steam, change launch command to prime-run %command%

          I have all of this (nvidia, steam, nvidia-settings nvidia-utils lib32-nvidia-utils nvidia-prime) and nothing works yet. I’m still trying to figure out what I can do.
