LD_DEBUG_OUTPUT isn't going to tell you anything new. The .NET runtime failed to load glfw, since it was linked against a glibc that was too new. Downgrading glfw probably won't be enough. At least the sqlite and openal libraries that come with Vintage Story were linked against more recent glibc versions (meaning they won't work on your system). If you have Slackware 15 versions for these installed, that may work. (Try "ldd ..." against all the files in the Lib dir with .so in their name.)

IMO, Slackware is an expert-only distribution. It has the worst package management / dependency tracking out there and has a tiny user base these days. It's extremely easy to end up with a broken system with incompatible or missing dependencies. No offense to OP, but he is running VS as root and very clearly not in the target audience. While I've been using Linux for 3 decades, I'm also aware of the fact that distributing software for it is a nightmare with dozens of distributions doing weird incompatible crap. The kernel itself has rather good backwards compatibility, pretty much everything else doesn't. Even if the libraries are compatible, there is a huge amount of "minor" surrounding things that aren't compatible between different versions, let alone different distributions. The error handling and reporting in the Linux graphics stack is absolutely atrocious.

Trying out that mod on some experimental save would be very enlightening. Most resources that people claim are rare are in fact extremely common and abundant. That specifically includes clay, bees and halite.

IME, iron is a lot easier to find than large amounts of copper and the other components for bronze. The iron deposit size is huge. I wouldn't go for bismuth bronze, unless I stumbled upon deposits. The alloy component deposits for tin/bismuth/zinc are small and you need a lot more for bismuth bronze compared to tin bronze. You only need small amounts of tin to progress to the iron age and buying it from a commodities trader is a very viable option. Meteoric iron is also very easy to find, if you know what to look for. I'm sitting on 250 ingots worth in my current game. You need an iron anvil to process meteoric iron and an iron pick-axe to mine it, but you get to skip the bloom processing stuff with meteoric iron. In terms of digging mining shafts down, you only need a ladder every other block. You should be placing ladders while you dig, otherwise you will hit and fall into a cave sooner or later with decent chance of dying.

Recent Vintage Story versions (including 1.21.6) come with the glfw library included (as Lib/libglfw.so.3). It gets properly loaded and used on my systems. The version that comes with Vintage Story is used, even if a system version of glfw is also installed. What does "ldd Lib/libglfw.so.3" run from the Vintage Story directory say? (glfw/libglfw is the same library it's trying to load using different possible names.) Does "glxgears" work and give you the spinning gears window?

That inxi output does look ok. The kernel i915 driver is used and X11 uses the correct modesetting driver. Do you have "glxinfo"? What does "glxinfo -B" say? Do you have the libraries from the files list of this package (I don't know if that binary package is trustworthy): https://slackware.pkgs.org/15.0/slackware-x86_64/mesa-21.3.5-x86_64-2.txz.html What does "LIBGL_DEBUG=verbose glxgears" say?

BTW, choosing Slackware this day and age seems like a very odd choice. I've used it 25+ years ago, but nowadays I can't think of a good reason to use it (and the current user base is TINY). If I wanted to tinker with stuff, I would use Arch (binary packages with no distro-tweaks and it's the base for SteamOS) or Gentoo (build from source). If I wanted something that most of time works well out of the box, I would choose some Debian or Ubuntu derivative. There is a variant for whatever desktop environment you want. Most Linux OS ISOs can be used as Live images booted from USB sticks without installation, so you can easily experiment with stuff.

You have glxgears, so you do have Mesa installed. Something is wrong with your graphics drivers. E.g., you might be using the generic VESA kernel module, instead of the proper i915 driver. The VESA driver works for basic things, but doesn't support graphics acceleration or 3D stuff like OpenGL. You have to install Perl for "inxi" to work. It can tell you your driver situation, without having to dig through other stuff. The output of "inxi -G" for a properly working setup would look something like this: Graphics: Device-1: Intel HD Graphics 620 driver: i915 v: kernel Display: x11 server: X.Org v: 21.1.11 with: Xwayland v: 23.2.6 driver: X: loaded: modesetting unloaded: fbdev,vesa dri: iris gpu: i915 resolution: 1920x1080~60Hz API: EGL v: 1.5 drivers: iris,swrast platforms: gbm,x11,surfaceless,device API: OpenGL v: 4.6 compat-v: 4.5 vendor: intel mesa v: 25.0.7-0ubuntu0.24.04.2 renderer: Mesa Intel HD Graphics 620 (KBL GT2) (Your integrated GPU is a HD Graphics 620.)

Your comment doesn't make any sense. A streamer who wants to cheat can trivially copy the save file (getting exactly the same world gen including ores) and explore the copy in creative mode and/or use a mod like Block Overlay.

Are you saying, you don't have Mesa installed (that would be rather surprising)? It should come with a tiny OpenGL demo app "glxgears". Do you have that? Does it work? What does "inxi -G" say?

My high-end system can start the game and load a save in 25 seconds. Your CPU isn't too bad, if your laptop has decent cooling and doesn't thermally throttle. Your 8GB RAM is very little and may be the reason for your bad performance. Performance absolutely tanks, when there isn't enough RAM and the system starts using swap.

Nobody has mentioned StepUp yet: https://mods.vintagestory.at/stepupcontinued It allows you to automatically and smoothly climb a single block without having to jump (a perfectly executed jump is slightly faster).

This should be impossible in Vanilla. It's not a predator. For something like a bear or wolf, the info text would be: "Partially eaten by another creature. Large bite marks.". It's not a rust creature, the info text would say "vile creature". It's not a player, the info text would say that. It's not lightning, the info text would say that. Your info text would correspond to another non-predator animal like a moose, but they don't attack pigs or sheep. The victims are aromatically tagged as partially eaten, when they are killed by a bear or wolf.

Have you looked at the Wiki? https://wiki.vintagestory.at/Temperature There is a pretty significant variation in local climate based on the noise map. There is also noise for the daily temperature. https://github.com/anegostudios/vsapi/blob/master/Common/Climate.cs#L50 For the actual temperature calculation, look at: https://github.com/anegostudios/vssurvivalmod/blob/master/Systems/Temperature.cs

IME, that's 100% nonsense. Terrain mods don't effect resource spawns beyond their expected effect on local climate. Elevation does effect climate and spawn conditions. Quite a lot of spawns depend on elevation.
