# Home Manager Config

## Systems

Current available systems are:

* `pc`  
My workstation PC running NixOS.
* `laptop`  
My laptop, a Thinkpad X1 Carbon Gen 7, also running NixOS.

After

## dconf

It is possible to observe live changes to dconf via `dconf watch /`.
If you want to convert the current dconf to a nix expression enter the dev shell with `nix develop` and do

```txt
dconf dump / | dconf2nix > dconf.nix
```

Build with

```txt
home-manager switch --flake .#[configuration]
```

After first deployment it suffices to do `hms` for `home-manager switch ...`.
This relies on the flake being saved to `$HOME/.config/home-manager`.

## Laptop

Specific instructions for the `Lenovo Thinkpad Yoga C13 (Morphius)`

Install Mr.Chromebox's [Firmware Utility Script](https://mrchromebox.tech/#fwscript).

Download [Fedora Workstation](https://www.fedoraproject.org/en/workstation/download).
Boot the Live USB in `minimal graphics mode`.
Install like usual but before restarting do edit the machine's kernel boot params like so:

```txt
sudo nano /mnt/sysroot/etc/default/grub
```

Add `iommu=pt` to `GRUB_CMDLINE_LINUX`.
Example:

```txt
GRUB_CMDLINE_LINUX="rd.luks.uuid=luks-6ee676a5-8f57-4400-bde6-2f5ff7c1260d nomodeset rhgb iommu=pt quiet"
```

Disable SELinux, as Nix does not work with it enabled

```txt
sudo nano /etc/selinux/config
```

and change `SELINUX=enforcing` to `SELINUX=permissive`

Resize the `/tmp` directory to allow for building large packages like `nerdfonts`

```txt
mount -o remount,size=25G /tmp
systemctl daemon-reload
```

Download the current home-manager config from <https://git.krsnik.at/Kristian/home-manager>.

```txt
cd home-manager
nix shell nixpkgs#home-manager --extra-experimental-features "nix-command flakes"
home-manager switch --flake .#laptop --extra-experimental-features "nix-command flakes"
```

Configure the following:

* syncthing
* gpg

In case ssh does not work work do

```txt
gpgconf --kill gpg-agent
```
