This patch fixes a bug caused by an incorrect reference to
'nvidiaSettings' rather than 'cfg.nvidiaSettings'. The bug caused
the system to not build when using the nvidia drivers.
Tested on my local machine.
- This is fetched from a different URL, so allow passing that explicitly.
- There also isn't an nvidia-persistenced or nvidia-settings release for
this version, so use 450.57 instead. Also implement passing
persistenced and settings version explicitly.

This fixes a harmless error from systemd-udevd that looks like:
Dec 23 15:35:23 dellbook systemd-udevd[696]:
/nix/store/iixya3ni5whybpq9zz1h7f4pyw7nhd19-udev-rules/99-local.rules:25
Invalid value "..." for RUN (char 101: invalid substitution type),
ignoring, but please fix it.
Using $$ fixes it using the escaping documented at https://www.freedesktop.org/software/systemd/man/udev.html.
The SLIM project is abandoned and their last release was in 2013.
Because of this it poses a security risk to systems, no one is working
on it or picked up maintenance. It also lacks compatibility with systemd
and logind sessions. For users, there liikely isn't anything like slim
that's as lightweight in terms of dependencies.
Invoke xrandr to actually connect the device.
Additionally, we let systemd create the logs directory and use our module loader
instead of handling it manually.
A new internal option `hardware.opengl.setLdLibraryPath` is added which controls if `LD_LIBRARY_PATH` should be set to `/run/opengl-driver(-32)/lib`. It is false by default and is meant to be set to true by any driver which requires it. If this option is false, then `opengl.nix` and `xserver.nix` will not set `LD_LIBRARY_PATH`.
Currently Mesa and NVidia drivers don't set `setLdLibraryPath` because they work with libglvnd and do not override libraries, while `amdgpu-pro`, `ati` and `parallels-guest` set it to true (the former two really need it, the last one doesn't build so is presumed to).
Additionally, the `libPath` attribute within entries of `services.xserver.drivers` is removed. This made `xserver.nix` add the driver path directly to the `LD_LIBRARY_PATH` for the display manager (including X server). Not only is it redundant when the driver is added to `hardware.opengl.package` (assuming that `hardware.opengl.enable` is true), in fact all current drivers except `ati` set it incorrectly to the package path instead of package/lib.
This removal of `LD_LIBRARY_PATH` could break certain packages using CUDA, but only those that themselves load `libcuda` or other NVidia driver libraries using `dlopen` (not if they just use `cudatoolkit`). A few have already been fixed but it is practically impossible to test all because most packages using CUDA are libraries/frameworks without a simple way to test.
Fixes #11434 if only Mesa or NVidia graphics drivers are used.
