In the absence of XCURSOR_PATH, the function XcursorLibraryPath in libXcursor will return a hardcoded value unsuitable for NixOS. Some desktops as well as display managers in NixOS currently do set XCURSOR_PATH, but there are combinations where neither does (e.g. SDDM+XFCE), resulting in no cursor themes being available. The new definition if XCURSOR_PATH is effectively the same as what KDE's startkde currently does. Fixes issue #21442.
*** NixOS *** NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at http://nixos.org/nixos and in the manual in doc/manual.
