So I ended up installing X through debian directly, and everything else with Nix. I think this isn’t going to work either though. Additional details: Optimus (?) laptop with intel/nvidia graphics, installed bumblebee-nvidia since bbswitch with nouveau simply didn’t work (high temperatures, fan constantly on while doing nothing).
So anyways, I installed picom, glxinfo, alacritty, etc with Nix and nothing that uses GLX will work.

These should work - the intel video also supports glx and there are no reported problems.
Since optimus feels like a massive hack I wasn’t expecting this to run, but:
~$ optirun glxgears
glxgears: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
I thought the issues with non-optirun might be related to libglx.so + related libraries which aren’t managed traditionally with optimus. Like, maybe it’s using a different libglx.so file for a driver that isn’t loaded on my system, whereas xdpyinfo which was installed with apt-get was.
I installed mesa-utils (for glxgears) with apt-get this time, and ran:
~$ /usr/bin/glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
1205 frames in 5.0 seconds = 240.932 FPS
So that appears to be the case.
Also, not directly X related but it seems chromium won’t work when installed with Nix on a foreign distro? It complains of a sandbox directory issue.
It’s going to be way too confusing managing some software with apt-get and some with Nix here, so I’m afraid I’m going to have to drop Nix at this point.
) be more in line with the spirit of the rule… but maybe not.
