config VS home-manager

Yes, that's correct. That's one of the tricky things with tmpfs roots. I had to do it in my configuration too.

To address the mouse travel in GNOME issue: you're right. What I did when I used GNOME 40 was a combination of hitting the super key to get to the exposé view, (hopefully that still works) and the hot edge extension which creates a more ergonomic way to reach it with the mouse. I had it installed declaratively with home-manager, but you can also do it manually.

Long answer: Even if it's just a colorscheme change, you still need to recompile because that's how DWM works. I happened to do exactly that with dmenu (and probably DWM soon) yesterday. Build dwm.src to see what you're patching, run diff to get the patch and presto.

To set up your VM, I would recommend libvirt, which serves as a graphical front-end to QEMU/KVM. I use it, I know other people use it and there are a lot of resources about setting up GPU VT-d on it out there. It's not significantly different under NixOS than it is under other distros. Here's how I declared it.

I really am at lost rn, foud this github issue tried the solution and it didn't work.

{ config, pkgs, ... }: { imports = [ (import "${builtins.fetchTarball https://github.com/rycee/home-manager/archive/master.tar.gz}/nixos") ]; users.users = { jdoe = { isNormalUser = true; initialPassword = "1234"; extraGroups = [ "wheel" ]; }; }; home-manager.useUserPackages = true; home-manager.users.jdoe = { home.stateVersion = "21.11"; programs.home-manager.enable = true; programs.git.userName = "John"; programs.git.userEmail = "Doe"; programs.zsh.zplug = { enable = true; plugins = [ { name = "zsh-users/zsh-autosuggestions"; } { name = "romkatv/powerlevel10k"; tags = [ as:theme depth:1 ]; } { name = "ohmyzsh/ohmyzsh oh-my-zsh"; } { name = "ajeetdsouza/zoxide"; } { name = "marlonrichert/zsh-autocomplete"; } { name = "marlonrichert/zsh-edit"; } { name = "zsh-users/zsh-autosuggestions"; } { name = "ptavares/zsh-exa"; } { name = "zsh-users/zsh-syntax-highlighting"; } { name = "mbenford/zsh-tmux-auto-title"; } { name = "zsh-users/zsh-history-substring-search"; } ]; }; services.gpg-agent = { enable = true; defaultCacheTtl = 1800; enableSshSupport = true; }; }; }

There are multiple ways of managing declarative profiles. 1) Attrset, compatible with imperative use of nix-env https://git.io/fAQHW ; 2) buildEnv, providing more control over the paths that are linked into the profile https://git.io/fp0aU ; 3) home-manager, providing nixos-like config for your ~ https://github.com/rycee/home-manager
