+=== Double suspend after GNOME automatic/idle suspend (systemd v258 regression) ===
+Some users have reported a "double suspend" / "suspend loop" on Framework Laptop 16 (notably with GNOME and the NVIDIA dGPU module): after the machine suspends due to *automatic idle suspend* and is resumed, it may suspend again ~20-30 seconds later (sometimes repeating multiple times). Manual suspend and lid-close suspend may still behave normally.
+Upstream tracking:
+* https://github.com/systemd/systemd/issues/40078
+* https://github.com/systemd/systemd/issues/39259
+==== Workaround 1: add a post-resume sleep inhibitor ====
+Add this snippet to configuration.nix:
+<syntaxhighlight lang="nix">
+systemd.services.inhibit-sleep-after-resume = {
+  description = "Temporary sleep inhibitor after resume (workaround for double-suspend)";
+  wantedBy = [ "post-resume.target" ];
+  after = [ "post-resume.target" ];
+  serviceConfig.Type = "oneshot";
+  script = ''
+    ${pkgs.systemd}/bin/systemd-inhibit \
+      --mode=block \
+      --what=sleep:idle \
+      --why="Workaround: avoid immediate second suspend after resume" \
+      ${pkgs.coreutils}/bin/sleep 60
+  '';
+};
+</syntaxhighlight>
+==== Workaround 2: disable GNOME idle-suspend (low risk; lid-close suspend still works) ====
+===== Quick (imperative) test =====
+Disable idle suspend on AC power:
+<syntaxhighlight lang="sh">
+gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'nothing'
+gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 0
+</syntaxhighlight>
+Optionally also disable it on battery:
+<syntaxhighlight lang="sh">
+gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type 'nothing'
+gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 0
+</syntaxhighlight>
+===== Declarative configuration (recommended) =====
+<syntaxhighlight lang="nix">
+{ lib, ... }:
+{
+# Declaratively set GNOME dconf defaults.
+programs.dconf.enable = true;
+programs.dconf.profiles.user.databases = [
+  {
+    settings = {
+      "org/gnome/settings-daemon/plugins/power" = {
+        # Disable idle-suspend on AC power (keeps lid-close suspend behavior):
+        sleep-inactive-ac-type = "nothing";
+        sleep-inactive-ac-timeout = lib.gvariant.mkUint32 0;
+        # Optional: also disable idle-suspend on battery:
+        # sleep-inactive-battery-type = "nothing";
+        # sleep-inactive-battery-timeout = lib.gvariant.mkUint32 0;
+      };
+    };
+  }
+];
+}
+</syntaxhighlight>
+After applying, log out and log back in (or reboot) to ensure GNOME picks up the updated settings.
+==== Workaround 3: pin nixpkgs to pre-systemd-v258 for the affected machine (higher impact) ====
+If you prefer to keep GNOME idle-suspend enabled, another workaround is to pin the affected system to a nixpkgs revision before systemd v258 landed.
+* Commit that introduced systemd v258: https://github.com/NixOS/nixpkgs/commit/70ca21d3c4982d7f95e48688d02cd9ef6b1347f5
