Motivation for this change

This pull request fixes default xorg.conf file, so xorg does not crash when starting and finds required modules. It also removes unnecessary xf86videodummy package and uses one from xorg.

Fixes #81425

Currently there is still another issue when starting xpra, so when starting you need to use: xpra start --daemon=no --fake-xinerama=no.

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 nixpkgs-review --run "nixpkgs-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.

Sorry, no idea about any of this X.org stuff, only touched the wrapGAppsHook parts.

@mjlbach do you have xpra in path on remote machine? I never tried it over ssh, only using locally over socket.

mjlbach commented Apr 3, 2020

Yes, it should be on the path of both, I can attach xpra from the client (my mac) to a remote ubuntu server, but not nix for some reason (see above error). Maybe should make a tracking issue for xpra problems...

Maybe issue would be good, so we someone can solve some other time when playing with xpra again.
