I'm using Mint21.3 Cinammon as well and have compiled and packed it with this version. This runs perfect on Mint21.3 Cinammon (my PC) itself but also on unmodified Mint22.3 live session and on Ubuntu 26.04 Desktop-amd64 live session if you install libsdl2-dev, both tested under Oracle Virtual box.

@matherp I tried both of the environment settings and still seg faulted. The gdb output refers to a library for the nvidia card driver I have in that box. I am trying to revert to the standard xserver and will give that a try. In the mean time I have installed on my Win11 box and that works fine. I will keep trying to sort this out. I take some comfort from @dddns that this is possible so I will try again with a clean install on another system.

I can report that reverting to the standard xserver solved the problem. The emulator works amazingly fast, which could be a real challenge for developing animations to run on the actual Pico Computer 3. I know that Nvidia drivers are not supported well on older versions of Linux and especially for older graphics cards (In my case an NVIDIA GEForce GTX 1050Ti). There is obviously some incompatibility in the libraries for those cards. It's a shame as I use those older machines running Linux for experimenting with CUDA to take advantage of the compute power in the GPU. My Win11 desktop has a RTX5060 Ti with 16GB memory for playing around with local AI models and the emulator under WSL and Ubuntu26.04 works great there.

I have test it on Fedora 44. It ran without any issues.

like @okwatts, built from source, but emulator crashed despite any startup options. MicroPython thread crashed in gdb, with similar nvidia library yelling.
I'm running current Debian with Wayland, and won't be going back to X11 to try other options. It was enough work getting this new(ish) machine working with the latest nvidia graphics that I don't want to mess with it any further.

Too many different distros, multiple releases LTS/current etc., totally impossible to ship an executable that just works. The source is there, if you can make it work fine, if not sorry but nothing I can do. If you use windows and follow the WSL instructions it will work and I've also tested building on a basic Ubunbtu machine and that also worked perfectly. Various users above have made it work on various flavours of Linux as reported above so there is clearly nothing fundamentally wrong. All I can suggest if it doesn't work is to use a VM with a known good environment and build within that
