Upgrade to NixOS 24.11 - display manger fails to start

Help
1

I attempted to upgrade to the 24.11 branch (314e12ba369ccdb9b352a4db26ff419f7c49fa84) but
rebooting fails because the display manager fails to start.

My configuration is standard:

  services.xserver.windowManager = {
      xmonad.enable = true;
      xmonad.enableContribAndExtras = true;
    };

  services.xserver.enable = true;
  services.xserver.displayManager.lightdm.enable = true;
  services.displayManager.defaultSession = "none+xmonad";
  services.xserver.xkb.layout = "gb";
  services.xserver.videoDrivers = ["intel"];
  services.xserver.xrandrHeads = [ "HDMI1" "HDMI2" ];

Does anyone have any ideas about what the problem might be?

It seems that it is segfaulting.

What is your services.xserver.videoDrivers ? This looks like issue #342763.

EDIT: I missed you had alrady posted it. Yes, you’re using the intel driver which is currently broken.

Thanks, I resolved this problem by looking at this issue. Xorg crashes at startup, starting graphical session impossible · Issue #352328 · NixOS/nixpkgs · GitHub
