Motivation for this change

We need a newer linuxPackages.evdi as well as an xorg.conf fragment in order for things to work with kernel 5.3.

Written from a USB3.0 connected displaylink screen, so this works.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nix-review --run "nix-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

This works with kernel 5.3.x

@GrahamcOfBorg build linuxPackages.evdi

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.
