I use home-manager to configure my keyboard shortcuts via dconf. This used to work fine but since a recent update on unstable I am seeing my keyboard shortcuts forgotten when I restart my machine (doesn't happen on just a log out, will check a restart of just gnome shortly...)

If I diff using the dconf2nix2 tool before and after I get:

❯ diff dconf-before.nix dconf-after.nix
110,111c110,111
<       sources = [ (mkTuple [ "xkb" "gb" ]) ];
<       xkb-options = [ "terminate:ctrl_alt_bksp" ];
---
>       sources = [ (mkTuple [ "xkb" "gb" ]) (mkTuple [ "xkb" "es" ]) ];
>       xkb-options = [ "terminate:ctrl_alt_bksp" "compose:ralt" "lv3:rwin_switch" ];
460a461
>       screensaver = [ "<Super>Escape" ];
553a555,556
>       toggle-message-tray = [ "<Super>v" ];
>       toggle-overview = [];

I use <Super>s and <Super>m for tiling window manager shortcuts which is what notice.

They are each mapped by default to one of toggle-message-tray, toggle-overview (forget which way around) so I remove each from the list to override.

Does anyone have any idea why my dconf settings are not persisting?

Silas Davis: you might want to try the "not-working" settings in services.xserver.desktopManager.gnome.extraGSettingsOverrides

In reply to @jtojnar:matrix.org
“so I remove each from the list to override” what list? How are you doing that? If you want to unset the keybinding, you will need to explicitly set it to empty list.

so...

I've taken a look at this file: /nix/store/22dzv5x7q98c890f67ilia4vwmhgxjzq-hm-dconf.ini

Which is referenced by /nix/store/rqyhp24x4cha7qx70i71rq0s32sd7hs1-home-manager-generation/activate:

$DRY_RUN_CMD $DCONF_DBUS_RUN_SESSION /nix/store/d9zam93fa4mj43fz3h09cajh81vgpqvn-dconf-0.40.0/bin/dconf load / < /nix/store/22dzv5x7q98c890f67ilia4vwmhgxjzq-hm-dconf.ini

It contains most of my custom settings, but where I have:

      "org/gnome/shell/keybindings" = {
        open-application-menu = [];
        toggle-overview = [];
        # Gnome tries to grab Super+m for this, the bastard
        toggle-message-tray = [ "<Super>v" ];
      };

It has:

$DRY_RUN_CMD $DCONF_DBUS_RUN_SESSION /nix/store/d9zam93fa4mj43fz3h09cajh81vgpqvn-dconf-0.40.0/bin/dconf load / < /nix/store/22dzv5x7q98c890f67ilia4vwmhgxjzq-hm-dconf.ini

gnome-settings-daemon is the component responsible for managing keybindings. For example, I get Failed to grab accelerator for keybinding when I switch to a home-manager config with conflicts.

Okay so nixos-rebuild --switch as ever restores my keys. Finding activate script:

systemctl show home-manager-silas.service | grep Exec

❯ cat activate | grep dconf
_iNote "Activating %s" "dconfSettings"
  /nix/store/83mizl0zb58zzyby47rk7iafa1mrrrmr-dconf-cleanup \

Now my settings are back:

[org/gnome/shell/keybindings]
open-application-menu=@as []
toggle-message-tray=@as ['<Super>v']
toggle-overview=@as []

After restart, broken:

❯ systemctl show home-manager-silas.service | grep ExecStart=

After nixos-rebuild --switch (working):
