Steam installs and runs, but RuneScape, while it launches and has audio, the window is completely black

Help

In the last fortnight, I’ve gotten back into running Linux as my daily driver after a break. My Arch Linux is up and running flawlessly, but my NixOS install has two major issues:

  • RuneScape running via Steam, while it launches, the window it launches is pitch black (despite audio playing)
  • VirtualBox, while it launches, virtual machines in it do not. There’s an execution error message that pops up. I’ll address this in another thread.

Needless to say neither of these issues occur under Arch Linux. RuneScape running via Steam actually runs flawlessly on Arch Linux, even better than the native Linux client. Later today, I plan on rebooting into NixOS and trying out any fixes you have to suggest to me. And, of course, gathering any debugging info you need.

Per the Wiki, I have tried adding:

programs.steam = {
  enable = true; # Master switch, already covered in installation
  remotePlay.openFirewall = true;  # For Steam Remote Play
  dedicatedServer.openFirewall = true; # For Source Dedicated Server hosting
  # Other general flags if available can be set here.
};

to my config and rebuilding. I’ve tried launching RuneScape with steam-run, such as with the command:

steam-run steam steam://rungameid/1343400

I think I also tried steam-run steam://rungameid/1343400. Neither fixed the issue. My graphics card is NVIDIA GeForce GTX 1050 Ti. And yes, I have the nvidia driver loaded in my config.

I realized when writing my initial post that I had omitted proprietary NVIDIA drivers from my configuration. Adding them with

hardware.graphics.enable = true;
  services.xserver.videoDrivers = [ "nvidia" ];
  hardware.nvidia.open = true;  # see the note above

Has set my display from 1920x1080 to 1024x768. Any ideas how to fix this?

Never mind, I found the reason. I need to set the final line (hardware.nvidia.open) to false, not true as my card is a bit older. On the bright side, the RuneScape issue is fixed. So I’m marking the previous comment as the solution.
