stuck creating nixos packages

[benneti]

I am trying to get breezy running on nixos, based on the aur package and the PR here.
I think I got everything building and starting, I also think both the gnome extension (shows as loaded in extensions) and the xr-driver.service (shows as active).
However when I start breezydesktop, I get

/nix/store/lxjfcdsyn5jnysl9l04mw47lbxigspvc-python3.12-pygobject-3.50.0/lib/python3.12/site-packages/gi/_gtktemplate.py:186: Warning: value "((GtkOrientation) 2)" of type 'GtkOrientation' is invalid or out of range for property 'orientation' of type 'GtkOrientation'
  base_init_template(self)
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:763: FINISHME: support YUV colorspace with DRM format modifiers
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:794: FINISHME: support more multi-planar formats with DRM modifiers

and the applications main window stays empty.
In .local/state/breezy_gnome/logs/ui/breezy_desktop.log I get
breezy_ui - ERROR - Could not verify your Breezy GNOME installation. Please ensure that Breezy GNOME is installed.
Note, I had to disable the verify process, because I did not figure out how to make it work with the different FS layout in nixos.
To this end I modified verify.py, where I removed the exit(1).

Any Idea what is going wrong / missing?
Also if I can provide any further information, let me know!

correction, I figured, I can just start with skipping the check using -sv

creating virtual monitors is still a bit funky, but I think this is due to get_bin_home(), is there a reason to not accept PATH. In nix it is quiet common, to have different programs in different places, due to how it tries to package stuff independent of each other.

Setting the BINDIR I got everything working now I'll share the config such that @shymega and others can take a look, after I had some time to extract it from my full config.

These are the files I used. I think they should compile everything from source, and don't require to copy anything to home manually. However, they are not of a particularly high quality and might contain unused dependencies.

breezy-gnome.nix.txt
default.nix.txt
xrlinuxdriver.nix.txt

as the package above works I'll close the issue
