4 days ago Yes, this looks look like a GPU drivers problem. As said above nixGL should fix that. https://geospatial-nix.today/ has built in support for nixGL (enable openGL in OTHER tab).

3 days ago I got the following set-up from geospatial-nix:
geopkgs = inputs.geonix.packages.${pkgs.system};
in {
packages = [
geopkgs.gdal-minimal
];
applications.qgis = {
enable = true;
package = geopkgs.qgis;
withGrass = false;
pythonPackages = p: [ ];
plugins = p: [ ];
};
nixgl.enable = true;
}When I start the shell some kind of massive compilation starts, it goes on for several hours until it exhausts RAM and crashes. I have 16 GB on chip plus 8 GB in swap.
Is there any alternative?

There should be no compilation. Everything should be downloaded from geospatial-nix binary cache. Did you accept it during the first start of geospatial-nix environment (Nix is asking few Yes/No questions) ?

I did not get any question from Nix. Is there any flag or parameter I could use to prevent compilation?

1 day ago You can try to remove ~/local/share/nix/trusted-settings.json file and run nix command again.
Also, you can try to use --accept-flake-config flag.

I just tried both things, but Nix still goes into compilations (see below). Is there any way to limit the number of cores and the RAM the compiler uses?

That's the issue. You are not trusted Nix user. Let me check how to fix it on Ubuntu.

Add yourself as user to /etc/nix/nix.conf.
trusted-users = <USERNAME>and restart nix-daemon sudo systemctl restart nix-daemon.service

1 day ago I expanded the Swap file quite a good deal and the compilation succeeded. At some point it took 22 GB of RAM. However, I still get the same exception when I start QGis (see below).
In the meantime I will add myself to the trusted users.

That's the issue with GPU driver which should be fixed using nixGL .
Describe the bug
QGis does not start, reporting an exception in the command line. Both from the main and from "unstable".
Steps To Reproduce
Expected behavior
The programme should start without exceptions.
Additional context
Nix 2.24.5 on Ubuntu 24.04.
